[0059] Example 1

[0060] Reference Figure 1 to Figure 3 , which is the first embodiment of the present invention, provides a protection control method for vectorized cryptographic operations, including:

[0061] S1: Use SIMD technology to build cryptographic algorithms and complete multi-channel data synchronization operations through cryptographic algorithms.

[0062] Among them, SIMD technology includes using SIMD instructions to control multiple transmission data at the same time, and the transmission data includes image information, audio information and text signal information.

[0063] Furthermore, the cryptographic algorithms include TDES algorithm, DES algorithm and AES algorithm, and the transmission channels of audio information, text signal information and image information are fitted using a data fitting model to obtain an encrypted channel;

[0064] The specific calculation formula of the TDES algorithm is:

[0065]

[0066] Among them, V represents the number of samples after the image information is fitted, Represents the features of the kth sample in the image sample V after the model output, represents the label corresponding to the kth sample feature in the image sample V, and α represents the image information data after fitting by the TDES algorithm;

[0067] The specific calculation formula of the DES algorithm is:

[0068]

[0069] in, Represents the features of the kth sample in audio sample A output by the model, represents the label corresponding to the k-th sample feature in audio sample A, β represents the audio information data after fitting by the DES algorithm, and g(·) represents the multi-classification cross entropy loss function;

[0070] The specific calculation formula of the AES algorithm is:

[0071]

[0072] in, Represents the features of the kth sample in the text signal information sample T after the model output, represents the label corresponding to the kth sample feature in the text signal information sample T, g(·) represents the multi-classification cross entropy loss function, and γ represents the text signal information data after fitting by the AES algorithm;

[0073] When the loss function is lower than the preset threshold, the data fitting model begins to take effect.

[0074] The threshold is an important parameter in the data fitting model, which is used to determine when the data fitting model begins to take effect. Specifically, when the value of the loss function is lower than the preset threshold, that is, the value of the loss function is less than a preset threshold, the data fitting model will begin to take effect.

[0075] For example, if the threshold is set to 0.05, when the value of the loss function drops to less than 0.05, the data fitting model will be activated and begin to fit the transmission channels of audio information, text signal information, and image information to obtain an encrypted channel. The setting of this threshold can be adjusted according to specific application scenarios and security requirements. It is usually optimized according to actual conditions to ensure the accuracy and effectiveness of the data fitting model. The comparison of the preset thresholds is shown in Table 1 below:

[0076] Table 1 Preset threshold comparison data table

[0077] Threshold describe 0.01 Very low threshold, high accuracy required 0.03 Lower threshold, moderately accurate 0.05 Medium threshold, balance between accuracy and efficiency 0.08 Higher threshold, acceptable accuracy 0.10 Relatively high threshold, low accuracy

[0078] The above table compares the impact of different loss function thresholds on the effectiveness of the data fitting model. By comparing the performance of 0.05 and other values, 0.05 was determined as the final threshold.

[0079] S2: Perform vectorization design of data blocks according to the results of data synchronization operations, and perform vectorization processing on data blocks according to the operation rules of the cryptographic algorithm and the SIMD data input requirements.

[0080] The vectorization design includes obtaining a time-frequency diagram by pre-emphasis, framing, windowing, calculating the power spectrum and filter bank of the audio information and text signal information, and adjusting the resolution of the time-frequency diagram. The specific steps are as follows:

[0081] Use SIMD instructions to collect the characteristics and advantages of cryptographic algorithms;

[0082] Determine the optimization strategy and deploy the optimized algorithm to the actual environment for maintenance and testing;

[0083] The testing involved using SIMD instructions to operate on multiple cryptographic algorithms in small groups simultaneously, using compact data structures to reduce the storage space requirements for data during the operations.

[0084] Furthermore, the text describes the vectorization design process for audio information and text signal information. First, the audio and text information are converted into time-frequency diagrams through pre-emphasis, framing, windowing, calculation of power spectrum and filter bank, and the resolution of the time-frequency diagram is adjusted. Then, SIMD instructions are used to collect the characteristics of the cryptographic algorithm, determine the optimization strategy, and apply the optimized algorithm to the actual environment and test it. During the testing phase, SIMD instructions are used to operate multiple cryptographic algorithms simultaneously, and compact data structures are used to reduce the data storage space requirements during the operation. This process takes advantage of the parallelism and efficiency of SIMD technology and improves the performance and efficiency of vectorized cryptographic operations.

[0085] S2.1: performing vectorized processing on a data block includes performing secondary operations on multiple cryptographic algorithms using SIMD instructions, the secondary operations include combining the results of multiple independent operations into one operation using SIMD instructions, storing the combined cryptographic algorithms using SIMD data structures, and performing secondary vectorized design on the algorithms based on the stored results and using SIMD instructions, the secondary vectorized design includes determining whether the cryptographic operations support SIMD instructions according to the system processor;

[0086] If the processor supports SIMD instructions, the data blocks are re-vectorized according to data synchronization operations;

[0087] Otherwise, an extraction is performed and secondary storage is performed using SIMD data structures;

[0088] The secondary vectorization design of the data block includes optimizing the algorithm that can reuse SIMD instructions according to the usage scenarios adapted to the characteristics and advantages of the cryptographic algorithm. The specific optimization steps are as follows:

[0089] Calculate the structure size of the transmitted data to determine the data block size;

[0090] Create SIMD data structures that conform to storage.

[0091] Furthermore, in the process of performing secondary vectorization on data blocks, first, SIMD instructions are used to perform secondary operations on multiple cryptographic algorithms, the results of multiple independent operations are merged into one, and the merged cryptographic algorithms are stored using SIMD data structures. Based on the storage results, SIMD instructions are used again to perform secondary vectorization design on the algorithm. In this process, whether the cryptographic operation supports SIMD instructions is determined based on the support of the system processor. If supported, the data block is secondary vectorized according to the data synchronization operation; if not supported, the SIMD data structure is used for secondary storage. According to the characteristics of the cryptographic algorithm and the usage scenario, the algorithm that can reuse SIMD instructions is selected for optimization, the data block size is determined by calculating the structure size of the transmitted data, and a SIMD data structure that meets the storage requirements is created. This process fully utilizes the advantages of SIMD instructions and data structures to achieve efficient processing and storage of cryptographic algorithms.

[0092] S3: Design algorithm branching based on the processed data blocks and perform verification to complete the protection control of vectorized cryptographic operations.

[0095] Encrypting the processed data block using the first key to obtain first encrypted data;

[0096] Decrypting the first encrypted data using the second key to obtain second encrypted data;

[0097] The second encrypted data is encrypted using the third key to obtain encrypted transmission data.

[0098] Furthermore, the verification includes using a verification algorithm to verify the data integrity of the encrypted transmission data. The specific calculation formula of the verification algorithm is:

[0099]

[0100] Where f(n) represents a linear function, w represents the weight coefficient of a single byte, and I (f) (w) represents the output value of the data integrity check result, n represents the number of data bytes, and m represents the number of byte characteristic elements;

[0101] Verify whether the encrypted transmission data is complete according to the above calculation formula;

[0102] If it is incomplete, the data information is prohibited from being transmitted to the data information receiving end, and an early warning signal is issued for early warning;

[0103] If complete, the data information is decrypted.

[0111] Reference Figure 1 to Figure 3 , which is the second embodiment of the present invention, and this embodiment provides a protection control method for vectorized cryptographic operations. In order to verify the beneficial effects of the present invention, scientific demonstration is carried out through simulation experiments.

Through experiments, it is found that merging the results of multiple independent operations into one can significantly improve the efficiency of the algorithm. In the experiment, different merging times are compared, and it is found that when the merging times reaches 3 times, the algorithm performance is optimal.

[0115] According to the support of the system processor, the data block is re-vectorized. On the processor that supports SIMD instructions, the data synchronization operation is re-vectorized to determine the size and storage structure of the data block. On the processor that does not support SIMD instructions, secondary storage is performed and a suitable data structure is used for storage.

[0116] The optimized cryptographic algorithm was experimentally verified. By testing the running time and efficiency of the algorithm under different data volumes, the performance improvement of the optimized algorithm was verified. The experimental results show that the proposed vectorized cryptographic operation scheme has higher efficiency and performance when processing large-scale data. Compared with traditional methods, it can significantly reduce the consumption of computing time and storage space. Different types of data sets are shown in Table 2 below:
