The article proposes a simple, scalable and robust scheme for the distribution of revocation information in mobile ad hoc networks (MANETs). The scheme is intended for ad hoc netwo...
It has been said that quantum cryptography in general o ers a secure solution to the problem of key enhancement. This means that two parties who already share a small secret key, ...
We introduce the novel concept of coprivacy or co-operative privacy to make privacy preservation attractive. A protocol is coprivate if the best option for a player to preserve her...
We introduce a protocol, that we call Human Key Agreement, that allows pairs of humans to establish a key in a (seemingly hopeless) case where no public-key infrastructure is avail...
We propose a generalization of Paillier's probabilistic public key system, in which the expansion factor is reduced and which allows to adjust the block length of the scheme e...
