Webb19 aug. 2024 · Cyber security has drawn more attention in the research of intelligent and unmanned ships. The remote control command transmitted in time sequence has a high similarity. This makes the ships more vulnerable to cyber-attacks, especially when they are controlled remotely. Aiming at the defense of Differential Fault Attack (DFA), this paper … WebbIt has the same key block length as the AES algorithm, and the security is higher than that of the 3DES algorithm. Compared with other encryption algorithms, the SM4 encryption … The SM4 algorithm was drafted by Data Assurance & Communication Security Center, CAS, and Commercial Cryptography Testing Center, National Cryptography Administration. It is mainly developed by Lü Shuwang (Chinese: 吕述望). The algorithm was declassified in January, 2006, and it became a … Visa mer ShāngMì 4 (SM4, 商密4) (formerly SMS4) is a block cipher used in the Chinese National Standard for Wireless LAN WAPI (WLAN Authentication and Privacy Infrastructure) and also used with Transport Layer Security Visa mer On March 21, 2012, the Chinese government published the industrial standard "GM/T 0002-2012 SM4 Block Cipher Algorithm", officially renaming SMS4 to SM4.
