....scheme, and the DSA. We also present some possible methods to counter the attack. 1 Introduction In September 1996, Boneh, DeMillo and Lipton from Bellcore announced a new type of cryptanalytic attack against RSA like public key cryptosystems on tamper resistant devices such as smart card [4]. However, technical details of the Bellcore attack were withheld in that announcement and was released only at the end of October 1996. On 18th October 1996, Biham and Shamir published their attack, called Differential Fault Analysis (DFA) to secret key cryptosystems [5] such as DES. Some ....
....world and the latter can be achieved by introducing some randomness in the intermediate stages of the cryptographic computation. a) The attacks may be avoided by calculating the output 2 times and matching the two results. However, this approach doubles the computational time. As pointed out in [4], this double computation method also avoids their attack. The weakness of this counter measure is that it slows down the computation by a factor of 2, which is not accepted for some applications [4] b) In many cases, the encryption key e is usually small. So we can verify the result by checking ....
