Description

technical field [0001] The invention relates to the security field, in particular to a device and method for resisting electromagnetic analysis attacks of security equipment. Background technique [0002] When a cryptographic algorithm is implemented on a certain physical device, various bypass information may be leaked, such as running time, power consumption, electromagnetic radiation, and so on. Attackers can use the part of these bypass information related to the key used by the cryptographic algorithm to crack the cryptographic system. Side-channel attack is an attack method to crack the cryptosystem by using the bypass information leaked when the cryptographic algorithm is implemented, such as time analysis attack, power consumption analysis attack, and electromagnetic analysis attack. [0003] Among them, electromagnetic analysis attack, as one of the most effective side-channel attack technologies for cryptographic algorithm chips, especially smart card chips, poses...
