A transitive signature scheme allows to sign a graph in such a way that, given the signatures of edges (a, b) and (b, c), it is possible to compute the signature for the edge (or ...
Optimistic fair exchange (OFE) is a protocol for solving the problem of exchanging items or services in a fair manner between two parties, a signer and a verifier, with the help o...

Since the Diffie-Hellman paper, asymmetric encryption has been a very important topic, and furthermore ever well studied. However, between the efficiency of RSA and the security of...
An untraceable fair network payment protocol is proposed by Wang in Asiacrypt’03, which employs the existent techniques of the offline untraceable cash and a new technique calle...
In this paper, we propose a notion of threshold tag-based encryption schemes that simplifies the notion of threshold identity-based encryption schemes, and we show a conversion fro...
