Abstract: Uses SDSoC technology to improve the traditional hash function (Hash Function) algorithm, and proposes an information encryption algorithm optimization model based on SDSoC technology. Algorithms are compared as well. The results show that the throughput of the hash function algorithm based on traditional hardware is lower, while the throughput of the AES algorithm based on SDSoC is higher; when the clock cycle is ap_clk, the target running time is Target, the evaluation running time is Estimated, and the error range time is Uncertainty , the running time of the traditional hash function algorithm is roughly in the range of 8.17±1.26, while the running time of the SDSoC-based AES algorithm is in the range of 8.11±1.20, and the execution speed of the improved algorithm is greatly improved. Therefore, the resource utilization rate of the improved algorithm is significantly lower than that of the traditional algorithm, which can improve the performance of the algorithm well, and the overall performance is higher.
