Description

Technical Field

[0001] This invention relates to the field of information security technology, specifically to a method for constructing a quantum-secure intelligent cloud service system. Background Technology

[0002] The construction of a quantum-safe intelligent cloud service system refers to the design and implementation of a highly secure cloud service system within a cloud computing environment, utilizing quantum communication and quantum encryption technologies. Specifically, this system ensures absolute data security during transmission through quantum encryption technologies such as quantum key distribution (QKD), preventing the vulnerability of traditional encryption methods. Simultaneously, the system integrates intelligent cloud resource management, dynamically scheduling computing and storage resources through artificial intelligence algorithms to optimize system performance and security. Quantum security technology enables cloud service transmission and storage to resist quantum computing attacks, significantly enhancing the system's security against future quantum computing threats, particularly suitable for data requiring high protection, such as in finance, healthcare, and government sectors. In this way, a cloud service system can be built that not only effectively defends against current threats but also resists new attacks arising from the development of quantum computing.

[0003] Existing technologies have the following shortcomings: In the construction of existing quantum-safe intelligent cloud service systems, key management conflicts in quantum key distribution (QKD) within multi-tenant cloud environments can lead to serious security issues. In a multi-tenant environment, multiple tenants share the same cloud platform resources, and each tenant's communication session typically requires an independent encryption key. If the quantum key generation and distribution processes between different tenants are not effectively isolated, it can lead to cross-use, leakage, or malicious tampering of keys. This situation can result in inconsistent key synchronization and may even expose some tenants' data to the risk of quantum computing attacks. Especially when key management and update timing cannot be precisely controlled, if key update delays or mechanisms malfunction, the security of the entire system may be compromised, leading to data leakage or tampering. Such problems are not easily detected in cloud computing environments, but once they occur, they can trigger serious security incidents, which are particularly crucial for data protection in industries such as finance and healthcare.

[0004] The information disclosed in the background section is only intended to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art. Summary of the Invention

[0005] The purpose of this invention is to provide a method for constructing a quantum-safe intelligent cloud service system. By allocating an independent quantum key generation module to each tenant, the method solves the problems of key cross-use and leakage in multi-tenant cloud environments. A quantum key update mechanism and precise synchronization control are introduced to ensure that keys are updated regularly and remain consistent, preventing security risks caused by key aging. Combining the physical principles of quantum indivisibility and superposition properties with quantum channel optimization, the system achieves secure and efficient key transmission. Real-time monitoring and anomaly detection promptly respond to potential security issues, improving the system's resistance to quantum computing attacks and overall security, thus addressing the problems mentioned in the background technology.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a method for constructing a quantum-safe intelligent cloud service system, comprising the following steps:

[0007] In a multi-tenant cloud environment, each tenant is assigned an independent quantum key generation module, and the key generation processes of each tenant are isolated from each other to prevent cross-use of keys;

[0008] In the quantum key distribution process, the generated encryption keys are distributed to the terminal devices of each tenant through a quantum communication network, and the key distribution process for each tenant is executed independently.

[0022] According to the security indicators of the key Adjust the transmission path and encryption algorithm of the quantum channel to ensure the security of the key transmission process;

[0023] By leveraging the indivisibility and superposition properties of quantum mechanics, the key is ensured to be protected from theft and tampering during transmission, and the key transmission rate is adjusted through a channel optimization algorithm.

[0024] Preferably, the quantum key update mechanism updates the key based on periodic time intervals, and an encrypted confirmation mechanism is used during the key update process to ensure that the key update operation is not performed by unauthorized users;

[0025] During key updates, keys are distributed to each tenant’s device via a quantum communication network, and process signaling is encrypted and verified using cryptographic algorithms.

[0026] Preferably, a quantum key authentication algorithm is used to ensure that each tenant's key is generated by a legitimate quantum key generation module, and a quantum key verification system is used to check the continuity and consistency of each key to prevent the key from being attacked or tampered with during storage or transmission.

[0027] Preferably, the monitoring system employs optical quantum detection technology to quickly detect potential key leaks and synchronization inconsistencies by monitoring the key transmission and update status of each tenant in real time.

[0028] The monitoring system combines the cloud platform's adaptive learning algorithm to dynamically adjust monitoring parameters based on the platform's operating status and changes in the network environment, ensuring that security vulnerabilities are detected and alerts are issued in the shortest possible time.

[0029] Preferably, the emergency key reset mechanism has the following specific steps:

[0030] When a key synchronization inconsistency is detected, the number of updated keys and the update rate are calculated using the following expressions:

[0031] In the formula, This refers to the number of keys that need to be updated. It is the first The tenant's old key, It is the first A new key for each tenant, It refers to the number of tenants;

[0032] Based on the update rate and the number of keys, a reset time window is calculated, and an independent key reset time is assigned to each tenant;

[0033] A reset command is sent to each tenant, and the key is updated via the quantum key distribution protocol;

[0034] After the update is complete, verification is performed using a key verification protocol to ensure that all tenants' keys have been successfully updated.

[0035] Preferably, to ensure the timeliness and security of key updates, the specific steps of the key update mechanism are as follows:

[0036] First, calculate the rate of change of the current key:

[0038] Use key change rate To predict future key changes and determine the frequency of the next key update, the following expression is used:

[0039] In the formula, It is the key update frequency. This is the maximum allowed update time;

[0040] Based on update frequency Based on the current tenant's key status, dynamically adjust the key update strategy to ensure that key update operations can be executed in a timely manner, avoiding the risk of key leakage and memory tampering.

[0041] Preferably, the key management system enhances the security of the quantum key through a quantum random walk algorithm, the calculation expression of which is as follows;

[0042] A quantum random path is generated using the quantum random walk algorithm, and the unpredictability of the key is calculated. The calculation expression is as follows:

[0043] In the formula, It is an indicator of the unpredictability of quantum keys. It is the step size of a quantum walk, representing the number of random steps a qubit takes during a quantum random walk;

[0044] Based on key unpredictability Adjusting the quantum key update strategy ensures that the key generation and update process is always in a highly secure state.

[0045] The technical effects and advantages provided by the present invention in the above technical solution are as follows:

[0046] This invention addresses the potential cross-use and leakage issues in key management within multi-tenant cloud environments by allocating an independent quantum key generation module to each tenant and strictly isolating the key generation and distribution processes of different tenants. Through the combination of quantum key distribution protocols (such as BB84) and quantum reflection technology, it ensures that keys are not subject to any interference or attacks during transmission, preventing key tampering and unauthorized access. This solution effectively prevents potential security vulnerabilities, ensuring that each tenant's encrypted information is protected within the cloud platform and avoiding data leakage or unauthorized access.

[0047] This invention introduces a quantum key update mechanism, combined with precise timing control and key synchronization strategies, to ensure that each tenant's encryption key is updated periodically during system operation, and that the updated key remains consistent across all tenants. Through an automated key update and synchronization mechanism, the system can promptly detect and correct inconsistencies in key synchronization and automatically adjust the frequency and timing of key updates, effectively avoiding security risks caused by key aging or delayed updates. This mechanism significantly improves system security and reduces data security vulnerabilities resulting from key expiration or update failures.

[0048] This invention achieves more secure and efficient key transmission by leveraging physical principles such as quantum indivisibility and superposition characteristics, along with quantum channel optimization techniques. Through real-time monitoring and quantum state detection technology, the system can monitor the key transmission status throughout the entire process, promptly detecting any potential key leaks, tampering, or synchronization inconsistencies, and responding immediately through an anomaly handling mechanism. This highly intelligent key transmission and anomaly detection capability ensures a high level of encryption protection for each tenant in the cloud service platform, while enhancing its resistance to quantum computing attacks. This enables the system to meet the challenges of future quantum computing technologies, significantly improving its anti-attack capabilities and stability. Attached Figure Description

However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the examples set forth herein; rather, they are provided so that the description of this disclosure will be more complete and fully convey the concept of the exemplary embodiments to those skilled in the art.

[0052] This invention provides, for example Figure 1 The method for constructing a quantum-safe intelligent cloud service system, as shown, includes the following steps:

[0053] In a multi-tenant cloud environment, each tenant is assigned an independent quantum key generation module, and the key generation processes of each tenant are isolated from each other to prevent cross-use of keys;

[0054] In the quantum key distribution process, the generated encryption keys are distributed to the terminal devices of each tenant through a quantum communication network, and the key distribution process for each tenant is executed independently.

[0055] The quantum key generation module uses a quantum random number generator (QRNG) to generate high-strength quantum random numbers, which are then used to generate initial quantum keys for encryption and decryption operations. This ensures that each tenant's key is unique and non-repeating within the quantum communication network.

[0056] The quantum key generation module uses a quantum optical system to generate keys by utilizing the principles of quantum indivisibility and superposition, thus making the key generation process impossible to steal or recover, and making key theft perceptible.

[0057] The quantum key generation module adjusts the key generation rate according to the needs of each tenant, and uses quantum state measurement technology to verify the key during the generation process to ensure that the key has not been attacked or tampered with.

[0058] The generation and verification process of quantum keys is encrypted to ensure that the keys are not subject to physical attacks or theft during transmission.

[0059] A quantum key update mechanism is adopted to perform key update operations periodically, and precise timing control of key synchronization between tenants is carried out through a quantum communication channel to ensure the timeliness and consistency of key updates.

[0060] The quantum key distribution process uses a quantum key distribution protocol (such as the BB84 protocol), which generates quantum keys between the cloud platform and each tenant's terminal device through photon generation and detection technology.

[0061] Each tenant terminal device receives the quantum key through the quantum key receiving module, ensuring that the key data is not stolen or tampered with during transmission;

[0062] The quantum key distribution protocol employs a quantum key transfer loop mechanism to correct errors in the transmitted qubits, thereby further improving the reliability and security of the quantum key.

[0063] Quantum reflection technology can effectively prevent keys from being attacked or interfered with during transmission, ensuring the stability and consistency of key transmission.

[0064] The specific steps for transmitting keys and maintaining high security through quantum channels during quantum key distribution are as follows:

[0065] In a quantum channel, the security index of the key is calculated using the following expression:

[0066] In the formula, It is an indicator of key security. It is the first The inner product between two quantum states of a qubit It is the quantum state received by the receiver. It is the quantum state sent by the sender. It is the number of qubits;

[0067] According to the security indicators of the key Adjust the transmission path and encryption algorithm of the quantum channel to ensure the security of the key transmission process;

[0068] By leveraging the indivisibility and superposition properties of quantum mechanics, the key is ensured to be protected from theft and tampering during transmission, and the key transmission rate is adjusted through a channel optimization algorithm.

[0069] Strict access control and auditing are implemented for the key management system of each tenant to prevent keys from being accessed or tampered with by unauthorized users;

[0070] The quantum key update mechanism updates the key based on regular time intervals, and uses an encrypted confirmation mechanism during the key update process to ensure that the key update operation is not performed by unauthorized users;

[0071] During key updates, keys are distributed to each tenant’s device via a quantum communication network, and process signaling is encrypted and verified using cryptographic algorithms.

[0072] The encryption confirmation mechanism is based on authentication technology. It uses quantum key authentication steps to ensure the legitimacy of each tenant's key update operation. During the key update process, all key changes are logged to facilitate subsequent auditing and traceability.

[0073] The quantum key authentication algorithm ensures that each tenant's key is generated by a legitimate quantum key generation module, and the quantum key verification system checks the continuity and consistency of each key to prevent attacks and tampering during storage or transmission.

[0074] Monitor and analyze the quantum key transmission and update status of all tenants within the cloud platform, promptly identify potential key management issues, and issue alarms for abnormal behavior;

[0075] The monitoring system uses optical quantum detection technology to quickly detect potential key leaks and synchronization inconsistencies by monitoring the key transmission and update status of each tenant in real time.

[0076] The monitoring system combines the cloud platform's adaptive learning algorithm to dynamically adjust monitoring parameters based on the platform's operating status and changes in the network environment, ensuring that security vulnerabilities are detected and alerts are issued in the shortest possible time.

[0077] When key synchronization inconsistencies or potential quantum computing attack risks are detected, the emergency key reset mechanism is automatically activated to quickly replace all affected encryption keys and restore the security of the cloud platform.

[0078] The specific steps of the emergency key reset mechanism are as follows:

[0079] When a key synchronization inconsistency is detected, the number of updated keys and the update rate are calculated using the following expressions:

[0080] In the formula, This refers to the number of keys that need to be updated. It is the first The tenant's old key, It is the first A new key for each tenant, It refers to the number of tenants;

[0081] Based on the update rate and the number of keys, a reset time window is calculated, and an independent key reset time is assigned to each tenant;

[0082] A reset command is sent to each tenant, and the key is updated via the quantum key distribution protocol;

[0083] After the update is complete, verification is performed using a key verification protocol to ensure that all tenants' keys have been successfully updated.

[0084] To ensure the timeliness and security of key updates, the specific steps of the key update mechanism are as follows:

[0085] First, calculate the rate of change of the current key:

[0086] In the formula, It is a moment Key change rate, It is a moment The key value, It is the key value from the previous moment. It is a moment timestamp, It is the timestamp of the previous moment;

[0087] Use key change rate To predict future key changes and determine the frequency of the next key update, the following expression is used:

[0088] In the formula, It is the key update frequency. This is the maximum allowed update time;

[0089] Based on update frequency Based on the current tenant's key status, dynamically adjust the key update strategy to ensure that key update operations can be executed in a timely manner, avoiding the risk of key leakage and memory tampering.

[0090] The key management system enhances the security of quantum keys through a quantum random walk algorithm, the calculation expression of which is as follows;

[0091] A quantum random path is generated using the quantum random walk algorithm, and the unpredictability of the key is calculated. The calculation expression is as follows:

[0092] In the formula, It is an indicator of the unpredictability of quantum keys. It is the step size of a quantum walk, representing the number of random steps a qubit takes during a quantum random walk;

[0093] Based on key unpredictability Adjusting the quantum key update strategy ensures that the key generation and update process is always in a highly secure state.

[0094] The use of this quantum random walk algorithm can ensure high complexity and unpredictability in the key generation process, thereby enhancing the overall security of the system and effectively preventing quantum computing attacks.

[0095] Implementation Method 1: In intelligent cloud service systems, ensuring the security of quantum key generation and distribution is crucial for guaranteeing the confidentiality of data transmission. This implementation method addresses the potential issues of key cross-use and leakage in multi-tenant environments by providing each tenant with an independent quantum key generation module.

[0096] First, each tenant's key generation module employs a high-strength quantum random number generator (QRNG), utilizing quantum physics to generate unpredictable random numbers, ensuring that the generated keys are unique and non-repeating. The high unpredictability of QRNG-generated random numbers effectively enhances security. Each tenant's key generation process is completely independent, ensuring key uniqueness. This mechanism effectively avoids key cross-referencing or sharing issues that can occur when multiple tenants share a single key generation module, thus guaranteeing complete protection for each tenant's data.

[0097] Next, the generated quantum key will be transmitted via a quantum key distribution protocol (such as the BB84 protocol). The BB84 protocol uses qubits to transmit the key, leveraging changes in the quantum state to ensure the security of the key during transmission. Due to the non-replicability of quantum states and the special properties of quantum measurement, any attempt to intercept the quantum key will corrupt the key state and be immediately detected. Therefore, the BB84 protocol ensures the confidentiality and integrity of key transmission through this characteristic.

[0098] To further enhance the security of the key transmission process, this implementation employs quantum reflection technology and a quantum key transfer loop mechanism. Quantum reflection technology enhances signal security and reduces the risk of signal loss, while the quantum key transfer loop mechanism ensures that the key transmission process for each tenant remains reliable throughout the channel, avoiding interference and potential attacks, and guaranteeing stable key transmission.

[0099] Furthermore, the key generation and distribution process in this implementation is strictly isolated to ensure that each tenant's key generation module is not interfered with by other tenants. The quantum key generation module operates independently in each tenant's environment, avoiding security vulnerabilities that could arise from multiple tenants sharing key generation resources. Through access control and auditing mechanisms, the system ensures that only authorized tenants can access and use their independent key generation modules. This isolation mechanism ensures complete independence of keys among tenants, preventing risks associated with cross-use or leakage of keys.

[0100] In a multi-tenant cloud environment, tenants share the computing and storage resources of the cloud platform, but each tenant's data and keys remain independent and confidential. This implementation solves the key collision and sharing problems that may occur in traditional encryption technologies through a quantum key generation and distribution isolation mechanism, ensuring the data security and privacy protection of each tenant within the cloud platform. This method is particularly suitable for industries requiring high confidentiality, such as finance, healthcare, and government, and can effectively address the new security threats brought about by the quantum computing era.

[0101] Through this independent key generation and distribution mechanism, this implementation method greatly improves the security and reliability of the cloud platform, avoids the potential threat posed by quantum computing to traditional encryption technology, and lays a solid security foundation for cloud service systems in the future quantum computing era.

[0102] Implementation Method Two: With the continuous development of cloud platform services, quantum security has become particularly important in ensuring data protection within cloud services. To address the potential threat to quantum keys during long-term use, this implementation method introduces a dynamic quantum key update mechanism and ensures key consistency among all tenants through precise synchronization control.

[0103] The quantum key update mechanism in this embodiment addresses potential security threats by periodically updating each tenant's encryption key. Key updates for each tenant are centrally scheduled by the system, and a quantum key update protocol ensures the key replacement process is not maliciously tampered with. During each key update, the system first generates a new quantum key and distributes it to each tenant's terminal device via a quantum communication network. To guarantee the security and integrity of the update process, all key update operations undergo cryptographic verification, ensuring that the update operation only applies to authorized tenants.

[0104] During the key update process, this implementation employs a precise timing control algorithm to ensure consistency and timeliness. The system sets an independent key update time window for each tenant to avoid conflicts between key update processes across multiple tenants. Real-time monitoring of each tenant's key ensures that no synchronization inconsistencies occur during the key update process. If any anomalies or potential security threats are detected during the update process, the system will immediately issue an alarm and automatically take emergency measures to ensure that all tenants' keys are updated in the shortest possible time, thereby restoring system security.

[0105] Furthermore, this implementation includes an emergency key reset mechanism. When the system detects key synchronization inconsistencies or an attack, this mechanism is automatically activated to quickly replace the keys of all affected tenants. This mechanism ensures that the security of the cloud platform is not severely compromised in the event of key leakage or tampering, and minimizes potential losses. The key reset operation is completed quickly, preventing the system from being exposed to potential risks for an extended period.

[0106] To improve the flexibility of key updates, this implementation introduces a two-way authentication mechanism based on a quantum key verification protocol. During each key update, the system rigorously verifies the new key to ensure its correctness and validity. The verification process employs quantum state measurement technology to check each bit of the key, ensuring that the updated key has not been tampered with and meets predetermined security standards. This verification mechanism prevents the forgery or malicious tampering of keys.

[0107] This implementation effectively avoids potential security threats to quantum keys during long-term use through this quantum key update and synchronization control mechanism. This mechanism not only ensures timely key updates but also guarantees the consistency of keys across all tenants through precise synchronization control, thus ensuring the encryption security of the entire cloud platform. This technical solution is significant for enhancing the cloud platform's resistance to attacks and mitigating the risks of quantum computing, and is particularly suitable for industries with extremely high data protection requirements, such as finance, healthcare, and government.

[0108] Implementation Method 3: In this implementation method, the present invention proposes a comprehensive solution to address the security issues in quantum key transmission, aiming to ensure high security and reliability of quantum keys throughout the entire process from generation to transmission and use. To cope with the parallel operation of multiple tenants in a cloud platform, this implementation method employs physical principles such as quantum indivisibility and superposition characteristics, quantum channel optimization technology, and real-time monitoring and anomaly detection mechanisms to solve potential security risks in key transmission, particularly preventing quantum computing attacks, key leakage, tampering, and synchronization inconsistencies.

[0109] First, during the transmission of the quantum key, quantum encryption technology is used to encrypt the key. Quantum encryption utilizes the principles of quantum mechanics to generate keys that possess inherent security and resistance to attacks. This is because any measurement of the key will cause an instantaneous change in its state, making any external monitoring attempt undetectable. This ensures a high level of security in quantum key transmission. Through this encryption method, the security of the key is fully guaranteed, avoiding the risk of leakage or tampering during transmission.

[0110] Furthermore, to further improve the transmission rate and stability of quantum keys, this implementation introduces quantum channel optimization technology. Quantum channel optimization technology maximizes signal quality and reduces signal loss by adjusting the transmission path of the quantum channel, thereby improving the integrity and effectiveness of the quantum bits during transmission. Through quantum channel optimization, the system can achieve faster and more stable quantum key transmission without compromising key security. Especially in long-distance transmission, quantum channel optimization effectively avoids transmission quality degradation caused by signal attenuation, thus ensuring that the quantum key is not lost or tampered with during transmission and maintains its encryption effect.

[0111] During quantum key transmission, the security of the cloud platform relies on the effective operation of the real-time monitoring module. This implementation integrates an advanced real-time monitoring system that can monitor the quantum key transmission process of each tenant in real time and track the key transmission status. By continuously collecting key data during the key transmission process, the real-time monitoring system can analyze any anomalies in the quantum channel in real time and react quickly based on the analysis results. Specifically, the system monitors key indicators such as the noise level, signal strength, and bit error rate of the quantum channel. Abnormal changes in these indicators can promptly reflect potential security risks during quantum key transmission.

[0112] Once the system detects a potential security issue, such as key leakage, tampering, or key synchronization inconsistency, the real-time monitoring system will immediately issue an alert and activate the anomaly handling mechanism. This mechanism responds to and resolves the issue through the following steps: First, the system performs an emergency check to confirm the occurrence of the security incident; second, the system automatically halts the currently affected quantum key transmission process and isolates the threatened key to prevent further spread; finally, the system initiates a key reset procedure, regenerating and transmitting a new key using the quantum key distribution protocol to ensure the restoration of security for each tenant's encrypted communication. This real-time monitoring and anomaly response mechanism ensures that the system reacts quickly to potential security threats and takes effective measures to prevent data leakage or tampering.

[0113] To further enhance the security of quantum key transmission, this implementation also employs quantum state detection technology to monitor the entire key transmission process. Quantum state detection technology utilizes the observation principle in quantum mechanics to detect the qubits in real time during transmission. By detecting the quantum state of each tenant's key transmission, the system can instantly detect whether the quantum key has been subjected to external interference or eavesdropping during transmission. This detection method has extremely high precision and accuracy because any measurement of a qubit will have an immediate impact on its state; therefore, the system can immediately detect any unauthorized measurement attempts.

[0114] Specifically, during quantum key transmission, the system monitors the quantum state changes of each qubit in real time and determines whether the key has been tampered with or stolen by comparing these changes with predetermined security standards. If an anomaly in the quantum state is detected, the system immediately initiates the corresponding security verification mechanism, confirming whether the key has been attacked by comparing its integrity. If verification fails, the system activates the key reset function to promptly replace the affected key, ensuring that the system's security is not compromised.

[0115] By combining physical principles such as quantum indivisibility and superposition, quantum channel optimization technology, real-time monitoring and anomaly detection mechanisms, and quantum state detection technology, this implementation method effectively addresses multiple security vulnerabilities in quantum key transmission. The physical principles of quantum indivisibility and superposition provide inherent resistance to eavesdropping; quantum channel optimization improves transmission rate and stability; real-time monitoring and anomaly detection ensure the system can quickly respond to and handle security incidents; and quantum state detection further ensures that every detail of the key transmission process is rigorously monitored. This organic combination of technologies significantly enhances the security of data within the cloud platform, enabling it to effectively defend against potential threats from future technologies such as quantum computing.

[0116] In summary, this implementation method constructs a complete quantum key transmission and anomaly detection mechanism through highly integrated quantum security technology. This not only ensures the secure encrypted transmission of each tenant's data within the cloud platform but also enhances the cloud platform's defense capabilities against future quantum computing attacks. Through the comprehensive application of the aforementioned technologies, this invention achieves end-to-end security during quantum key transmission, effectively improving the overall system's resistance to attacks and ensuring that the cloud platform maintains a high level of security and reliability even when facing new security challenges.

[0117] This invention addresses the potential cross-use and leakage issues in key management within multi-tenant cloud environments by allocating an independent quantum key generation module to each tenant and strictly isolating the key generation and distribution processes of different tenants. Through the combination of quantum key distribution protocols (such as BB84) and quantum reflection technology, it ensures that keys are not subject to any interference or attacks during transmission, preventing key tampering and unauthorized access. This solution effectively prevents potential security vulnerabilities, ensuring that each tenant's encrypted information is protected within the cloud platform and avoiding data leakage or unauthorized access.

[0118] This invention introduces a quantum key update mechanism, combined with precise timing control and key synchronization strategies, to ensure that each tenant's encryption key is updated periodically during system operation, and that the updated key remains consistent across all tenants. Through an automated key update and synchronization mechanism, the system can promptly detect and correct inconsistencies in key synchronization and automatically adjust the frequency and timing of key updates, effectively avoiding security risks caused by key aging or delayed updates. This mechanism significantly improves system security and reduces data security vulnerabilities resulting from key expiration or update failures.

[0119] This invention achieves more secure and efficient key transmission by leveraging physical principles such as quantum indivisibility and superposition characteristics, along with quantum channel optimization techniques. Through real-time monitoring and quantum state detection technology, the system can monitor the key transmission status throughout the entire process, promptly detecting any potential key leaks, tampering, or synchronization inconsistencies, and responding immediately through an anomaly handling mechanism. This highly intelligent key transmission and anomaly detection capability ensures a high level of encryption protection for each tenant in the cloud service platform, while enhancing its resistance to quantum computing attacks. This enables the system to meet the challenges of future quantum computing technologies, significantly improving its anti-attack capabilities and stability.
