Protocols proven secure within the universal composability (UC) framework satisfy strong and desirable security properties. Unfortunately, it is known that within the “plain” m...
Abstract. A (k; n)-robust combiner for a primitive F takes as input n candidate implementations of F and constructs an implementation of F, which is secure assuming that at least k...
A large number of vulnerabilities occur because protocol implementations failed to anticipate illegal packets. rfcs typically define what constitute “right” packets relevant ...
The recently proposed universally composable (UC) security framework for analyzing security of cryptographic protocols provides very strong security guarantees. In particular, a p...
Abstract. Oracle separation methods are used in cryptography to rule out blackbox reductions between cryptographic primitives. It is sufficient to find an oracle relative to whic...
