WebbA key leakage Trojan circuit was designed and the original circuit was SM4, a Chinese block cipher algorithm standard, and the trigger part is composed of sequential and combinational circuits, so the hardware Trojan would be triggered only when the conditions are met for both two kinds of circuits. 1 WebbSM algorithm constraints: SM2, SM3, and SM4 are Chinese national cryptography standards. To avoid legal risks, these algorithms must be used together. If you specify the SM4 algorithm to encrypt CEKs when creating a CMK, you must specify the SM3 and SM4 algorithms (SM4_SM3) to encrypt data when creating CEKs.
