摘　　要：Dear editor,Implementation attacks such as fault attack(FA)[1]and side-channel analysis(SCA)[2]are significant threats to the cryptographic device security.Infective countermeasure is a promising strategy to resist FAs.Its principle is to scramble the data path of the encryption and make the faulty ciphertext useless in the key retrieval.The scrambling here is called infection.It can be executed either once at the end of the algorithm or multiple times between different encryption operations.

关 键 词：operations multiple FAULT
