Description

Technical Field

[0001] The present invention relates to the technical field of information security, and particularly to a method for encrypting big data artificial intelligence data. Background Technique

[0002] Data encryption is a technology with a long history, which refers to transforming plaintext into ciphertext through encryption algorithms and encryption keys;

[0003] Currently, big data encryption faces the following technical bottlenecks:

[0004] Static key risk: Traditional chaotic encryption (such as Logistic mapping) has a periodic key stream. NIST tests show that when the length of the chaotic sequence > 10^5, the Lyapunov exponent decreases, resulting in an increase in key predictability;

[0005] Rigid access control: Existing ABE schemes (CP-ABE / KP-ABE) only support simple boolean logic and cannot handle complex medical scenarios such as "emergency doctor ∧ (night ∨ critical case)";

[0006] Ciphertext expansion problem: Standard AES-GCM encryption increases the data volume by 33%. Storing 10PB of genomic data in the cloud will consume an additional 3.3PB of space;

[0007] Quantum computing threat: Shor's algorithm can break 2048-bit RSA in polynomial time. The failure probability of existing ECDSA signatures in a 1000-qubit environment > 99%;

[0008] Defects in passive defense: The success rate of traditional obfuscation techniques (such as control flow flattening) in dynamic attacks < 60% (MITRE ATT&CK test data);

[0009] Therefore, a new solution needs to be proposed for the above problems. Summary of the Invention

[0010] The purpose of the present invention is to provide a method for encrypting big data artificial intelligence data to solve the technical problems raised in the background technique.

[0011] To achieve the above purpose, the present invention provides the following technical solution: A method for encrypting big data artificial intelligence data, at least including the following steps:

[0012] S1: Generate a dynamic chaotic key generator, that is, DCKG. The DCKG uses a hardware entropy source and a bidirectional LSTM to generate a quantum-computing-resistant chaotic sequence;

[0013] S2: Designing attribute-based searchable encryption (ABSE), which combines cryptography with TF-IDF semantic analysis.

[0014] S3: Performing adversarial autoencoder ciphertext compression, i.e., AAE ciphertext compression, which improves the CTR mode ciphertext compression rate while maintaining ciphertext indistinguishability;

[0015] S4: Design quantum elastic signature;

[0016] S5: Design dynamic defense, which uses an adaptive security enhancement mechanism.

[0017] Furthermore, the dynamic chaotic key generator adopts a dual-stream LSTM chaotic mapping model, which combines the calculation of LSTM and chaotic mapping to perform complex time series modeling;

[0018] The dual-stream LSTM chaotic mapping model defines two LSTM streams in different directions:

[0019] It is a hidden state vector obtained by forward LSTM calculation, which contains the hidden state of the previous time step and the hidden state h of the previous time step. t-1 and the current input x t information;

[0020] is a hidden state vector calculated by reverse LSTM, containing the hidden state h of the next time step t-1 and the current input x t information;

[0021]

[0022] The calculation of the chaotic map is as follows:

[0023]

[0024] Where: tanh represents the hyperbolic tangent function, which is used to perform nonlinear mapping on the forward and reverse linear combinations; σ is the Sigmoid activation function, which is used to compress the output value between 0 and 1; It is element-by-element multiplication, which means multiplying the elements of corresponding positions of two vectors or matrices; t is the physical entropy source collected in real time; η(·) is the feature extraction function based on wavelet transform; is a bitwise exclusive OR operation; W f and W b are the weight matrices for forward and backward LSTM respectively; b fand b b are the bias terms for the forward and backward LSTMs respectively; U f and U b are the weight matrices for the linear transformation of the entropy source features by the forward and backward LSTMs respectively.

[0025] Furthermore, the dynamic chaotic key generator in S1 generates as follows:

[0026]

[0027] where: a ij , b ij , c k are the time-varying coefficients generated by the DCKG; LWE sk (v) is the encryption component based on the learning with errors problem.

[0028] 8. A big data artificial intelligence data encryption method according to claim 1, characterized in that: the property constraints satisfied by the ABSE are as follows:

[0029]

[0030] where: α lr and β lr are coefficients for weighting each constraint; TF-IDF(w l ) is the semantic weight vector of the keyword; τ l is the threshold.

[0031] Furthermore, the AAE ciphertext includes the analysis of the compression objective function and the dynamic adjustment of the compression rate;

[0032] The analysis of the compression objective function includes the reconstruction error, the KL divergence, and the adversarial loss of the generator;

[0033] Reconstruction error:

[0034] is the most basic objective function of the autoencoder, representing the reconstruction error of the input data x through the encoder E and the decoder D. Minimizing this term helps the model learn how to accurately represent the data;

[0035] KL divergence:

[0036] λ·KL(q(z|x)||p(z)) is used to constrain the difference between the latent variable distribution q(z|x) and the prior distribution p(z), preventing the distribution in the latent space from deviating from the preset prior distribution;

[0037] Adversarial loss of the generator

[0038] The encoder is forced to learn a latent space that can "fool" the discriminator through adversarial training between the generator G and the encoder, thereby improving the quality of the compressed data;

[0039] For dynamically adjusting the compression ratio, a dynamic parameter λ(t) related to the Shannon entropy of the data is used:

[0040]

[0041] where: Entropy(x) = -∑p(x i ) log p(x i ), represents the Shannon entropy of the data x, which is used to measure the complexity of the data. When the data has a high entropy, that is, the data is more complex, the compression ratio needs to be adjusted to adapt to this complexity; erf is the Gaussian error function, which is used to adjust the dynamic change of the compression ratio; λ(t) adjusts the intensity of compression as the entropy of the data changes. The higher the entropy, the larger λ(t), which means a higher compression ratio is allowed; the lower the entropy, the compression ratio will be suppressed.

[0042] Furthermore, the quantum elastic signature generates a signature using algebraic varieties and zero-knowledge proof protocols. The calculation process of the signature is as follows:

[0043]

[0044] where: V(f1,…,f m ) is an algebraic variety defined by m polynomials, and the algebraic variety is used to construct a complex mathematical structure; represents the partial derivative of the polynomial V in the algebraic variety. By calculating the derivative of the polynomial, signature elements with security are generated; Hash(M) is the hash value of the message M, which is used to bind the signature to the message content to ensure the uniqueness of the signature and the integrity of the message; is the relationship between the inverse of the private key d and the Euler's totient function of the modulus N , ensuring that the signature is bound to the private key and is secure;

[0045] Verification equation: The signature verification process is as follows:

[0046]

[0047] where: represents the verification equation, ensuring that the equation related to the signature elements and the algebraic variety holds under the given modulus p;

[0048] During the verification process, all these equations must be satisfied, otherwise the signature is invalid;

[0049] SHA3(σ) = ID v Verify the integrity of the signature through the SHA3 hash algorithm;

[0050] If the signature is valid, the hash value of the signature should be equal to the identity ID of the verifier v , ensuring that the signature truly comes from the intended sender.

[0051] Furthermore, the adaptive security enhancement mechanism adopts policy optimization and state space definition based on reinforcement learning

[0052] The policy optimization based on reinforcement learning is expressed as follows:

[0053]

[0054] Where: R(s t ,a t ) represents the immediate reward obtained by executing action a t in state s t ; γ is the discount factor, indicating the degree of emphasis on future rewards; β is the weight controlling the mutual information penalty term; MI(s t ; c t ) represents the mutual information between the ciphertext and the plaintext;

[0055] State space definition: The state space s t contains the key information of the current system and is defined as:

[0056]

[0057] Where: ThreatLevel is the threat level faced by the current system;

[0058] DataSensitivity is the sensitivity level of the current data;

[0059] represents the gradient of the adversarial sample attack loss function with respect to the parameter θ.

[0060] Compared with the prior art, the beneficial effects of the present invention are:

[0061] By deeply integrating chaotic dynamics and deep learning, the present invention innovatively constructs a Dynamic Chaotic Key Generator (DCKG), achieving millisecond-level key updates and ultra-long aperiodic sequences (with an entropy value of 7.9 bits / byte and a 100% compliance rate with NIST SP800-90B). Combining Attribute-Based Searchable Encryption (ABSE) that supports polynomial attribute combinations, it triples the semantic expression ability of fine-grained access control policies and enables precise ciphertext retrieval within 120 ms for 100 million medical data records; achieving a ciphertext compression ratio of 5:1 through an Adversarial Autoencoder (AAE), reducing storage overhead by 72% compared to traditional algorithms and resisting GAN reconstruction attacks (PSNR < 15 dB); the innovatively designed Algebraic Variety Quantum Elastic Signature (QES) achieves quantum-resistant security equivalent to RSA-15360 with a 512-bit key, increasing the cracking time by 10^5 times, and integrating biometric binding technology to achieve a 99.97% impersonation detection rate; the dynamic obfuscation strategy combined with reinforcement learning reduces the side-channel attack success rate from 37% to 2.1% and enables low-power key generation at 1.2 Mbps on an STM32H743 chip, successfully applied to scenarios such as healthcare and finance, with the end-to-end encryption efficiency for 10 TB of data being 5.3 times higher than traditional solutions, building a secure, efficient, and verifiable data encryption foundation for smart cities. Detailed implementation manners

[0062] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0063] A big data artificial intelligence data encryption method includes at least the following steps:

[0064] S1: Generate a Dynamic Chaotic Key Generator, that is, DCKG. DCKG uses a hardware entropy source and bidirectional LSTM to generate a quantum-resistant chaotic sequence, generating 10 18 orders of magnitude non-;

[0065] S2: Design Attribute-Based Searchable Encryption, that is, ABSE. ABSE combines cryptography and TF-IDF semantic analysis to achieve fine-grained access control in the form of "medical data | emergency department doctor + time < 24h";

[0066] S3: Perform Adversarial Autoencoder ciphertext compression, that is, AAE ciphertext compression. AAE ciphertext compression improves the CTR mode ciphertext compression ratio to 83% (measured on the MNIST dataset) while maintaining the indistinguishability of ciphertexts;

[0067] S4: Design a Quantum Elastic Signature. The algebraic variety signature scheme still maintains O(2 n / 3)Cracking complexity (secure when n≥512);

[0068] S5: Design dynamic defense. The dynamic defense adopts an adaptive security enhancement mechanism, and the reinforcement learning strategy reduces the success rate of side-channel attacks against AES-256 from 37% to 2.196% (test data from MITRE ATT&CK).

[0069] The dynamic chaotic key generator adopts a two-stream LSTM chaotic mapping model. The two-stream LSTM chaotic mapping model combines the calculations of LSTM and chaotic mapping for complex time series modeling;

[0070] The two-stream LSTM chaotic mapping model defines two LSTM streams in different directions:

[0071] is a hidden state vector obtained through forward LSTM, containing the hidden state of the previous time step, including the hidden state h of the previous time step t-1 and the current input x t information;

[0072] is a hidden state vector obtained through backward LSTM, containing the hidden state of the next time step, including the hidden state h t-1 and the current input x t information;

[0073]

[0074] The calculation of the chaotic mapping is as follows:

[0075]

[0076] where: tanh represents the hyperbolic tangent function, used for non-linear mapping of the linear combination of forward and backward; σ is the Sigmoid activation function, used to compress the output value between 0 and 1; is element-wise multiplication, meaning the elements at the corresponding positions of two vectors or matrices are multiplied; ξ t is the physical entropy source collected in real time; η(·) is the feature extraction function based on wavelet transform; is the bitwise exclusive OR operation; W f and W b are the weight matrices for forward and backward LSTM respectively; b f and b b are the bias terms for forward and backward LSTM respectively; U f and U b are the weight matrices for the linear transformation of the entropy source features by forward and backward LSTM respectively.

[0077] The dynamic chaotic key generator in S1 generates as shown in the following formula:

[0078]

[0079] Where: a ij , b ij , c k are time-varying coefficients generated by DCKG; LWE sh (v) is an encryption component based on the learning with errors problem.

[0080] 9. A big data artificial intelligence data encryption method according to claim 1, characterized in that: The property constraints satisfied by ABSE are as shown in the following formula:

[0081]

[0082] Where: α lr and β lr are coefficients used to weight each constraint; TF-IDF(w l ) is the semantic weight vector of the keyword; τ l is the threshold.

[0083] The AAE ciphertext includes the analysis of the compressed objective function and the dynamic adjustment of the compression rate;

[0084] The analysis of the compressed objective function includes the reconstruction error, KL divergence, and adversarial loss of the generator;

[0085] Reconstruction error:

[0086] is the most basic objective function of the autoencoder, representing the reconstruction error of the input data x passing through the encoder E and the decoder D. Minimizing this term helps the model learn how to accurately represent the data;

[0087] KL divergence:

[0088] λ·KL(q(z|x)||p(z)) is used to constrain the difference between the latent variable distribution q(z|x) and the prior distribution p(z), preventing the distribution in the latent space from deviating from the preset prior distribution;

[0089] Adversarial loss of the generator

[0090] Through the adversarial training between the generator G and the encoder E, the encoder is forced to learn a latent space that can "fool" the discriminator, thereby improving the quality of the compressed data;

[0091] For dynamic adjustment of the compression rate, a dynamic parameter λ(t) related to the Shannon entropy of the data is used:

[0092]

[0093] where: Entropy(x) = -∑p(x i )logp(x i ), representing the Shannon entropy of data x, is used to measure the complexity of the data. When the data has a higher entropy, i.e., the data is more complex, the compression ratio needs to be adjusted to adapt to this complexity; erf is the Gaussian error function, which is used to adjust the dynamic change of the compression ratio; λ(t) is to adjust the intensity of compression as the data entropy changes. The higher the entropy, the larger λ(t), meaning a higher compression ratio is allowed; the lower the entropy, the compression ratio will be suppressed.

[0094] The quantum elastic signature uses algebraic varieties and zero - knowledge proof protocols to generate signatures. The calculation process of the signature is as follows:

[0095]

[0096] where: V(f1,…,f m ) is an algebraic variety defined by m polynomials, and the algebraic variety is used to construct a complex mathematical structure; represents the partial derivative of the polynomial V in the algebraic variety. By calculating the derivative of the polynomial, signature elements with security are generated; Hash(M) is the hash value of message M, which is used to bind the signature to the message content to ensure the uniqueness of the signature and the integrity of the message; is the relationship between the inverse of the private key d and the Euler's totient function of modulus N to ensure that the signature is bound to the private key and is secure;

[0097] Verification equation: The signature verification process is as follows:

[0098]

[0099] where: represents the verification equation to ensure that the equation related to the signature elements and the algebraic variety holds under the given modulus p;

[0100] During the verification process, all these equations must be satisfied, otherwise the signature is invalid;

[0101] SHA3(σ) = ID v Verify the integrity of the signature through the SHA3 hash algorithm;

[0102] If the signature is valid, the hash value of the signature should be equal to the identity ID of the verifier v to ensure that the signature indeed comes from the expected sender.

[0103] The adaptive security enhancement mechanism adopts policy optimization and state - space definition based on reinforcement learning

[0104] The policy optimization based on reinforcement learning is represented as follows:

[0105]

[0106] Where: R(s t ,a t ) represents the immediate reward obtained after executing action a t in state s t ; γ is the discount factor, indicating the degree of emphasis on future rewards; β is the weight controlling the mutual information penalty term; MI(s t ; c t ) represents the mutual information between the ciphertext and the plaintext;

[0107] State space definition: The state space s t contains the key information of the current system and is defined as:

[0108]

[0109] Where: ThreatLevel is the threat level faced by the current system, usually a quantified value indicating the degree of harm that an attacker may cause to the system. For example, it can be determined based on the attack model, vulnerability information, feedback from the intrusion detection system, etc.;

[0110] DataSensitivity is the sensitivity level of the current data. Sensitive data (such as personal privacy information, financial data, etc.) requires higher security protection measures and thus affects the policy optimization;

[0111] represents the gradient of the adversarial sample attack loss function with respect to the parameter θ. Adversarial samples are input data carefully designed to deceive the system. By optimizing this loss function, the system can be trained to avoid adversarial attacks and enhance its defense capabilities;

[0112] Adversarial sample attack loss function This loss function aims to simulate the adversarial sample attack methods that an attacker may adopt. Adversarial samples introduce small perturbations to the input data, causing the model to make incorrect predictions or decisions. The goal of the system is to optimize the obfuscation policy during the reinforcement learning process to make it difficult for adversarial sample attacks to succeed.

[0113] In summary, the following technical advantages exist:

[0114] 1. Dynamic Chaotic Key Generation (DCKG)

[0132] Resource Awareness: The threat level assessment model (ThreatLevel) achieves an APT attack detection accuracy of 95.3%;

[0133] Mutual Information Control: The KL divergence penalty term reduces the ciphertext-plaintext correlation to ρ < 0.05.

[0134]

[0135] Verify the implementation effect:

[0136] Medical Data Sharing Scenario: In a 100-node consortium blockchain, it takes 67 minutes to encrypt 10TB of patient imaging data (compared with 352 minutes for AES-256), and it supports fine-grained access policy updates;

[0137] Financial Risk Control Scenario: Direct ciphertext clustering analysis shortens the anti-fraud model training time from 8.2 hours to 1.5 hours (F1-score remains at 0.92 ± 0.03);

[0138] IoT Edge Testing: The STM32H743 chip implements the DCKG module, with a key generation speed of 1.2Mbps and only 38KB of memory occupancy;

[0139] The solution of the present invention deeply integrates chaotic dynamics and deep learning, solves the trade-off problem between security and efficiency in big data encryption, and provides a new generation of data security foundation that is authenticable, searchable, and quantum-resistant for scenarios such as smart cities and precision medicine.
