The objective of this paper is to propose a cryptographic protocol which provides authenticity in the exchange of information between two entities without using any shared secret ...
Group key exchange protocols allow a group of servers communicating over an asynchronous network of point-to-point links to establish a common key, such that an adversary which fu...
We propose an efficient and flexible system for a secure and authentic data exchange in a multiinstitutional environment, where the institutions maintain different databases and p...

Abstract. Many real-world protocols, such as SSL/TLS, SSH, IPsec, IEEE 802.11i, DNSSEC, and Kerberos, derive new keys from other keys. To be able to analyze such protocols in a com...
Secure two-party authentication and key exchange are fundamental problems. Traditionally, the parties authenticate each other by means of their identities, using a public-key infr...
