Description

Technical Field

[0001] The invention belongs to the field of key detection, and in particular relates to a universal key management detection method. Background Art

[0002] There is currently no unified standardized process for key detection, mainly because different software vendors and operating systems may have different key formats and verification mechanisms. The following are some factors that may lead to the lack of standardization of key detection: 1. Different key types: Software products may use different types of keys, and the verification method of each key may be different.

[0003] 2. Different operating systems: Different operating system versions, such as Windows 10, Windows 7, Windows 8, etc., may have different key verification mechanisms.

[0004] 3. Different software products: In addition to operating systems, there are many other software products that may have their own key verification systems.

[0005] 4. Different activation servers: Software vendors may use different activation servers, which may have different verification protocols and processes.

[0006] 5. Security and anti-piracy measures: To protect intellectual property and prevent piracy, software vendors may regularly update their key verification systems, which may result in detection tools needing to be constantly updated to maintain compatibility.

[0007] 6. Third-party detection tools: There are many third-party key detection tools on the market, and the detection methods and accuracy of these tools may vary.

[0008] 7. Regional differences: Laws and regulations in different regions may affect the key activation and detection process.

[0009] Due to the above factors, key detection usually requires relying on detection tools for specific software or operating systems, which need to be updated regularly to adapt to new verification mechanisms and security measures. When using these tools, users need to ensure that they come from trusted sources and understand their detection methods and limitations. Summary of the invention

[0010] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a universal key management detection method.

[0011] The object of the present invention is achieved through the following technical solution: a universal key management detection method, comprising: Determine the key to be tested and the testing tool; Testing the key; Generate a detection conclusion according to the detection result of the key; Among them, detecting the key includes: detecting the cryptographic architecture, the key generation process, the key distribution process, the key storage method, the key usage method, the key update method, the key destruction method, the key backup method and the key recovery method respectively.

[0012] Furthermore, the key architecture is tested, including: Check whether a key hierarchy is established and whether the keys are protected according to the hierarchy; Check whether keys at different levels achieve top-down security protection; Analyze the type and purpose of each key and detect whether the key hierarchy is secure.

[0021] The beneficial effects of the present invention are: (1) The existing key detection method does not have a detection standard corresponding to the entire life cycle of the key, and the key systems of different products do not have unified detection requirements and solutions, and a universal key management detection method has not been formed. In response to these problems, the present invention proposes a universal key life cycle management detection method.

This standardized method makes the detection process more consistent, reduces the detection differences caused by different products or systems, and thus improves the efficiency and accuracy of detection; (2) The present invention does not rely solely on a single detection method, but combines a variety of technologies, tools and methods, such as regular expression matching, static code analysis, log auditing, etc. This multi-dimensional detection strategy can more comprehensively cover various potential security vulnerabilities and risks, thereby improving the comprehensiveness and effectiveness of detection; (3) By providing a simplified user interface and an automated detection process, the present invention reduces the technical threshold and complexity of key management detection.

[0023] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0024] See also Figure 1 to Figure 2 The present invention provides a universal key management detection method: like Figure 1 As shown, a universal key management detection method includes steps S100 to S300.

[0025] Step S100: Determine the key to be tested and the testing tool.

[0026] Specifically, a key to be tested is obtained, a key testing tool is determined, and the key to be tested is input into the key testing tool.

[0027] Step S200: Detect the key.

[0028] Specifically, the detection tool is connected to the server to detect the key.

[0029] like Figure 2As shown, the key is tested, including: testing the cryptographic architecture, key generation process, key distribution process, key storage method, key usage method, key update method, key destruction method, key backup method and key recovery method respectively.

[0030] In some embodiments, the key architecture is detected, including: detecting whether a key hierarchy is established and whether the keys are protected according to the hierarchical relationship; detecting whether keys at different levels achieve top-down security protection; analyzing the type and purpose of each key, and detecting whether the key hierarchy is secure.

[0031] The key architecture is tested according to the application of cryptographic products.

[0032] When testing the key system architecture, if the key system has only one layer, the output is insecure; if the key system only contains symmetric keys, the security of the key system needs to be further verified in combination with the key generation process.

[0033] In some embodiments, the key generation process is detected, including: detecting whether each key generation method is generated through random number generation, key negotiation or derivation; detecting whether the random number generation mechanism complies with relevant standard requirements, whether the key negotiation process is secure, and whether the derivation mechanism complies with relevant standard requirements; detecting whether the key generation process is recorded and audited.

[0034] The generation of keys should be based on sufficient randomness to ensure that the generated keys are unpredictable. A random number generator or entropy source can be used to obtain sufficient randomness, and relevant randomness tests and analysis can be performed.

[0035] The generated key should be strong enough to resist various attacks and cracking attempts. Cryptographic algorithms and evaluation tools can be used to evaluate the strength of the key, such as entropy test and exhaustive search.

[0036] The key generation process should be carried out in a secure environment to prevent the key from being maliciously obtained or tampered with. Physical security measures, access control and encrypted transmission can be taken to ensure the security of the key generation process.

[0037] Detailed recording and auditing of the key generation process is helpful for tracking and analyzing possible problems or anomalies. The recorded information includes the generation time, generator, and generation parameters. Auditing can be carried out through logging, monitoring tools, etc.

[0038] In this embodiment, by detecting the key generation process, it is possible to ensure that the generated key has sufficient strength and randomness, thereby improving the security and reliability of the key.

[0039] When testing the key generation process, if the key is not generated by a random number generator approved by the national cryptography administration, is not generated through key negotiation, or is not externally imported, then the output is unsafe. If the randomness test of the key is not performed, a risk warning is output; if the strength test of the key is not performed, a risk warning is output; if the key generation fails, a risk warning is output.

[0040] In some embodiments, the key distribution process is detected, including: detecting whether the key distribution process is protected by an encryption algorithm or implementing security protection in the key distribution process through a threshold algorithm; detecting whether anti-replay, anti-tampering and anti-interception attack are achieved in the key distribution process, and whether confidentiality, integrity and identity authenticity protection are achieved in the key distribution process.

[0041] For example, check whether public key encryption is used, whether key exchange protocol is used, whether digital signature algorithm is used, whether key distribution center is used, and whether other methods are used to ensure the security of key distribution process.

[0042] Public key encryption: Using the public key encryption algorithm, the communicating party can use the other party's public key to encrypt the key, and then send it to the other party. Only the other party with the private key can decrypt the original key.

[0043] Key exchange protocol: Using the key exchange protocol, the communicating parties can negotiate and generate a shared key by sending some information to each other over an insecure communication channel. This process ensures that the key is known only to the communicating parties.

[0044] Digital signature: Using a digital signature algorithm, the sender can sign the key and the receiver can verify the authenticity of the signature, thus ensuring that the key has not been tampered with during transmission.

[0045] Key distribution center: Use a trusted third-party organization as the key distribution center, through which the communicating parties can obtain keys.

[0046] Other methods: By verifying the key distribution principle and implementation mechanism, and through code review, etc., determine whether the security of key distribution meets the security requirements.

[0047] When checking whether the key distribution complies with the security mechanism, if the key is not distributed through ciphertext, not distributed through threshold algorithm key components, and not distributed using a security mechanism approved by the national cryptography administration department, then the output is unsafe. If the key distribution fails, a risk warning is output.

[0048] In some embodiments, the storage method of the key is detected, including: detecting whether secure storage or encrypted storage is achieved through physical means; detecting whether the encryption protection method complies with relevant standard requirements or meets security requirements.

[0049] For example, the key storage method can be tested from aspects such as key storage security, whether the key is backed up, whether the key is stored separately, key management system and physical security.

[0050] Security of key storage: Keys are the key to protecting communication content, so the security of keys is very important; keys should be stored in a secure place and only authorized personnel can access them; measures such as password protection, access control and encryption can be used to enhance the security of keys.

[0051] Is the password backed up: In order to prevent the loss or damage of the key, the key should be backed up regularly, and the backed-up key also needs to be stored securely to prevent it from being obtained by unauthorized personnel.

[0052] Whether the key is stored separately: To increase the security of the key, the key can be stored separately.

[0053] Key management system: For large-scale key storage and management, a key management system can be used to centrally manage and control keys.

[0054] Physical security: The storage medium of the key should have good physical security.

[0055] When testing the storage method of the key, if the key is not protected by encryption storage, micro-electric protection or other security mechanisms, the output is unsafe. If the key storage does not implement access control, the output is unsafe. If the key used for a long time is not backed up, a risk warning is output; if the key storage fails, a risk warning is output.

[0056] In some embodiments, the usage of the key is detected, including: detecting whether the key has a unique purpose; detecting whether different keys are used according to the designed purpose during use, and whether different key purposes are mixed; detecting whether the key usage authority is determined first during use.

[0057] When detecting the usage of the key, if the key cannot be used normally, a risk warning will be output; if the key is not used for a single purpose, it will be output as unsafe; if the key is not used according to the designed key policy purpose, it will be output as unsafe; if the key usage authority is not verified before use, it will be output as unsafe.

[0058] In some embodiments, the key update method is detected, including: detecting whether the key update cycle is set according to the purpose and frequency of use of the key; detecting whether the key update strategy is secure and whether security is guaranteed during the update process; detecting whether the key is updated in accordance with the security policy when the key is leaked or there is a security risk.

[0059] For example, check whether the key update cycle is set according to the purpose and frequency of use of the key, including: check whether keys with higher usage rates have shorter update cycles; check whether keys used for a long time have an update cycle set, and perform key updates according to the updated strategy.

[0060] For highly sensitive or high-risk keys, updates should be performed more frequently. Ensure that all keys that need to be updated are included in the detection scope.

[0061] When a key update failure or abnormality is detected, it should be handled in a timely manner to ensure the integrity and security of the key.

[0062] When detecting the key update method, if the key update strategy is not designed according to the key purpose and frequency of use, a risk warning is output; if the key cannot be updated normally, a risk warning is output; if a key update failure or abnormality is detected and is not handled in time to ensure the integrity and security of the key, an unsafe output is output; if the key is leaked or there is a security risk and the key is not updated according to the security policy, an unsafe output is output.

[0063] In some embodiments, the method of destroying the key is detected, including: detecting whether the key can be restored after being destroyed; detecting whether the destroyed key can be used; and detecting whether the method of destroying the key meets security requirements.

[0064] Key destruction must ensure that the destroyed key is no longer effective for use.

[0065] When detecting the key destruction method, if the key destruction method is evaluated to be unsafe, the output is unsafe; if the key can still be used after destruction, the output is unsafe; if the key can be recovered after destruction, the output is unsafe; if the key destruction fails, a risk warning is output.

[0066] In some embodiments, the key backup method is detected, including: detecting confidentiality and integrity during the key backup process; detecting whether the frequency of key backup is performed in accordance with the key policy.

[0067] The key should have a backup function when needed.

[0068] For example, based on business needs and security standards, determine the scope of key backup that needs to be tested and the frequency of testing; use key management systems, security tools or manual methods to test key backups; analyze the test results to identify possible problems or deficiencies; based on the test results, optimize the key backup strategy to improve backup efficiency and security; record the test process and results, and generate corresponding reports for subsequent audits and reviews.

[0069] When testing the key backup method, if the key backup frequency is not implemented in accordance with the key policy, the output is unsafe; if the backup does not achieve key confidentiality and integrity protection, the output is unsafe; if the key backup fails, a risk warning is output.

[0070] In some embodiments, the key recovery method is detected, including: detecting whether the frequency of key recovery is performed in accordance with the key policy; detecting whether key recovery is used as a regular security audit activity to ensure the continued effectiveness of the key recovery policy; and detecting whether identity authentication is performed before key recovery.

[0071] Testing the key recovery method is a key step to ensure that the key can be successfully recovered according to the predetermined recovery strategy in the event of key loss or damage.

[0072] During the key recovery test process, ensure that the test keys and recovery strategies are not accessed or leaked by unauthorized personnel, and ensure that the key recovery test does not cause any interference or impact on the production environment.

[0073] Step S300: Generate a detection conclusion based on the key detection result.

[0074] Specifically, based on the detection result of the key, a detection conclusion is generated according to preset rules.

[0075] All the standards involved in this embodiment are corresponding industry standards or national standards. For example, whether the random number generation mechanism meets the requirements of relevant standards, whether the key negotiation process is secure, and whether the derivation mechanism meets the requirements of relevant standards are detected. The standards involved in this step are GM / T 0005 Randomness Detection Specification, 7GM / T 0003.3 SM2 Elliptic Curve Public Key Cryptography Algorithm Part 3: Key Exchange Protocol, and GM / T 0091 Password-Based Key Derivation Specification.

It should be understood that the present invention is not limited to the form disclosed herein, and should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be modified within the scope of the concept described herein through the above teachings or the technology or knowledge of the relevant field.
