Security Attack Detection Method Combining Side Channel with Fault Injection

Thereare still many problems in the actual deployment of both masking technology and out-of-order technology. In this paper, the typical SCA (Side channel attack) technology is studied, and an improved side channel analysis method is designed. From the perspective of coding mode, a security attack detection method combining side channel and fault injection is proposed. After obtaining the leak, the attacker needs to combine the known plaintext and ciphertext information according to the leak model, and extract the key information hidden in the leak information by using certain analysis methods. The faults in the words sensitive to faults are dispersed in a plurality of words insensitive to faults, and the number of faults in each word is odd as far as possible, thus improving the fault detection rate. The experimental results show that when there is no fault injection in all paths except the fault-sensitive path, the fault detection rate can be obtained with less resources by using word recombination parity, and SCA detection under SDN can be well realized.
