We present the first cryptographically sound Dolev-Yaostyle security proof of a comprehensive electronic payment system. The payment system is a slightly simplified variant of t...
In this paper we focus on tackling the insecurity problem of security protocols in the presence of an unbounded number of data such as nonces or session keys. First, we pinpoint f...
Meadows recently proposed a formal cost-based framework for analysis of denial of service. It was showed how some principles that have already been used to make cryptographic prot...
This paper presents a new protocol for certified email. The protocol aims to combine security, scalability, easy implementation, and viable deployment. The protocol relies on a li...
In an oblivious transfer (OT) protocol, a Sender with messages M1, . . . , MN and a Receiver with indices 1, . . . , k [1, N] interact in such a way that at the end the Receiver ...
