We introduce (i) a general class of security protocols with private channel as cryptographic primitive and (ii) a probabilistic epistemic logic to express properties of security pr...
Body Area Networks (BAN) is a key enabling technology in E-healthcare such as remote health monitoring. An important security issue during bootstrap phase of the BAN is to securely...
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...
Distributed key generation is one of the most challenging tasks for threshold cryptosystems. Designing such a protocol and proving its security against a malicious, adaptive adver...
Public key based authentication and key exchange protocols are not usually designed with privacy in mind and thus involve cleartext exchanges of identities and certificates before ...
