[Free60-Devel] RSA fault attacks

2005-12-21 Thread James Muir
List members who have an interest in cryptography (RSA, in particular) 
may find the following two papers interesting:


1. On authenticated computing and RSA-based authentication
http://portal.acm.org/citation.cfm?id=1102120.1102138

2. Seifert's RSA fault attack:  simplified analysis and generalizations
http://www.ccsl.carleton.ca/~jamuir/papers/rsa-faults.pdf

The papers show that if an adversary can flip a few bits of an RSA 
modulus stored inside a computer, then there is a good chance that they 
can force the computer to accept a signature on an unauthorized message.


The Xbox is mentioned in both papers.
