Abstract. Proactive routing protocols for mobile ad hoc networks currently offer few mechanisms to detect and/or counter malevolent nodes. Stability and performance of most, if not...
We construct efficient universally composable oblivious transfer protocols in the multi-party setting for honest majorities. Unlike previous proposals our protocols are designed in...
Abstract Two protocols for authentication based on symmetric key cryptography are described, where the verifier can be implemented in software completely, without the need for secu...
There are two main ways of defining secrecy of cryptographic protocols. The first version checks if the adversary can learn the value of a secret parameter. In the second version,...
Clustering and data aggregation in wireless sensor networks improves scalability, and helps the efficient use of scarce resources. Yet, these mechanisms also introduce some securi...
