摘要: The international standard signature algorithm DSA has been guaranteed its security based on discrete logarithm problem. Recently, the was known to be vulnerable some fault analysis attacks in which secret key stored inside of device can extracted by occurring faults when performs algorithm. After analyzing an existing attack presented Bao et al., this paper proposed a new disturbing random number. Furthermore, we countermeasure compute that immunity two types attacks. and efficiency were verified computer simulations.
