| 摘 要： | Introduction Since Boneh et al1]announced a model forbreaking public key cryptographic schemes by tak-ing advantage of random hardware faults in 1996,fault analysis has become an important aspect ofcrypto-analysis method. Fault analysis inducesfaults in tamper-resistant chips by means of radia-tion, X-rays, micro-probing or cut wires, so thatsome information of keys could leak from chips. Biham &Shamir applied fault attack to the ex-tension of block cipher cryptosystems such asDES, and call…

| Abstract: | Substitution permutation network (SPN) is one important structure of block cipher cryptosystems. Prior work has shown different fault analyses on SPN. The formalization of fault analysis of both attack and protect on SPN have been given. The overhead and time tolerance of fault detection have been discussed. The pseudo-blinding method to detect fault attack is introduced, and the balance of the security, overhead and time tolerance based on the evaluation could be made. |
