Research on Fault Attack Against Software Application of RSA
Fang Yu-qi · Jisuanji gongcheng · 2011
The object of former RSA fault attack is the software ran in hardware,such as smartcard.In order to research on fault attack against software implementation of RSA,the software implementation algorithm of Chinese Remain Theorem(CRT) is analyzed,the fault attack algorithm against OpenSSL's implementation of RSA is proposed.It proposes an advanced attack scheme which only needs once faulty signature.Simulation results show that the proposed algorithm has feasibility to break the RSA's signature key,and some countermeasures are presented to defend this kind of attack.
