WebbSM4 [ISO.IEC.18033-3.AMD2] is a cryptographic standard issued by the Organization of State Commercial Administration of China as an authorized block cipher for the use … WebbSM4, where r i represents a dual cipher of the SM4 algorithm. The steps of Shi et al.’s white‐box SM4 implementation are as follows. Step 1 Select an arbitrary dual cipher r j from R, and make the corresponding transformation to the i‐th round of the SM4 algorithm: Take the corresponding matrix of r j as

WebbWith the widespread application of power Internet of Things (IoT), the edge IoT agents are often threatened by various attacks, among which the white-box attack is the most serious. The white-box implementation of the cryptography algorithm can hide key information even in the white-box attack context by means of obfuscation. However, under the … Webb20 aug. 2014 · In 2009, Xiao and Lai [12] proposed a white-box SM4 implementation using lookup tables and affine transformations. However, in 2013, Lin and Lai [13] presented an attack on Xiao and Lai's... 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.
