Analysis of Cloud Computing Security Based on SGX Enhanced National Secret Algorithm

摘要

The operation security of national secret algorithm is an important research issue in the field of cloud computing security. This paper studies and proposes a cloud computing security operation scheme for SGX enhanced national security algorithm. Based on the analysis of SGX technology and national security enhanced algorithm, the cloud computing environment for SGX enhanced national security algorithm is constructed. The accuracy rate of SM3 algorithm and HMAC algorithm for SM3 is 100%, both of which can calculate the hash value correctly. When the algorithm runs 800 times, the overall running time of the original SM3 algorithm, the running time of the enhanced SM3 algorithm itself, the running time of the enhanced SM3 initialize Enclave, and the overall running time of the enhanced SM3 algorithm are about 0.1s, 0.5s, 14s, 15s, respectively.
