Ad hoc networks are dynamic networks formed "on the fly" by a set of nodes. Achieving secure routing in such networks is a big challenge. Asymmetric signature schemes pr...

We propose the first forward-secure signature scheme for which both signing and verifying are as efficient as for one of the most efficient ordinary signature schemes (Guillou-Qui...

We propose a new notion of cryptographic tamper evidence. A tamper-evident signature scheme provides an additional procedure Div which detects tampering: given two signatures, Div...

In earlier work, we described a “pathological” example of a signature scheme that is secure in the Random Oracle Model, but for which no secure implementation exists. For that...

Abstract. Recently we showed how to justify a Dolev-Yao type model of cryptography as used in virtually all automated protocol provers under active attacks and in arbitrary protoco...
