II. Attacks and Defences A. First Attack by Boneh Initially published in 1997 by Boneh et al [3], a fault-based attack can be easily performed on the CRT based RSA algorithm. The idea here is that given a faulty mes-
WebAug 28, 2011 · RSA–CRT fault attacks have been an active research area since their discovery by Boneh, DeMillo and Lipton in 1997. We present alternative key-recovery attacks on RSA–CRT signatures: instead of targeting one of the sub-exponentiations in RSA–CRT, we inject faults into the public modulus before CRT interpolation, which makes a number … Weban RSA implementation using the Chinese remainder theorem, RSA-CRT, and is known as the Bellcore attack. The Bellcore attack aroused great interest and led to many publications about fault attacks on RSA-CRT,e.g., [1,6,9,11,22]. Countermeasures to prevent the Bellcore attack can be categorized into two families: the rst one relies on a modi ...
