A desirable goal for cryptographic protocols is to guarantee security when the protocol is composed with other protocol instances. Universally Composable (UC) protocols provide th...

We present a mathematical construct which provides a cryptographic protocol to verifiably shuffle a sequence of k modular integers, and discuss its application to secure, universa...
We study the problem of "privacy amplification": key agreement between two parties who both know a weak secret w, such as a password. (Such a setting is ubiquitous on th...
This paper presents a new identity based key agreement protocol. In id-based cryptography (introduced by Adi Shamir in [33]) each party uses its own identity as public key and rece...
Information sharing and protection against leakage is a critical problem especially for organisations having sensitive information. Sharing content between individuals in the same...
