SM4 is a commercial block cipher standard, so it is very important to protect SM4 in WBAC and prevent malicious users illegally benefiting from distributingits key. In 2009, Xiao and Lai made the first and so far the only attempt to design a white-box SM4 implementation (WBSM4) 18 , 19 . WebbFor a more detailed introduction to SM cryptographic algorithms, please see Section 1.1.These cipher suites follow the TLS 1.3 requirements. Specifically, all the cipher suites use SM4 in either Galois/Counter (GCM) mode or Counter with CBC-MAC (CCM) mode to meet the needs of TLS 1.3 to have an encryption algorithm that is Authenticated … notion self care https://jamconsultpro.com
