In this paper we present a new compression scheme for signature tree structures. Beyond the reduction of storage space, compression attains significant savings in terms of query pr...

The signcryption is a relatively new cryptographic technique that is supposed to fulfill the functionalities of encryption and digital signature in a single logical step. Several ...
For the two last decades, electronic authentication has been an important topic. The first applications were digital signatures to mimic handwritten signatures for digital document...
Abstract--We consider the use of threshold signatures in adhoc and dynamic groups such as MANETs ("mobile ad-hoc networks"). We first show that known threshold RSA signat...

We introduce the notion of hierarchical group signatures. This is a proper generalization of group signatures, which allows multiple group managers organized in a tree with the si...
