    摘要: The present invention discloses an INS network-based anti-fault attack method of random infection, comprising the steps of sending the plain-text into an encryption processor, wherein two groups of cipher text are outputted through temporal or spatial redundancy; conducting XOR operation) on the two groups of said cipher text output to obtain the output difference; sending the said output difference into an infection function module to initiate an infection operation to obtain the infection result; conducting XOR operation on any of said groups of cipher text output to generate the final output. The present invention can realize the randomization of infection function in infection countermeasures, reduce the successful probability of fault attack and improve the safety of the circuit.
