The aim of this paper is to provide an overview for the research that has been done so far in signcryption area. The … paper also presents the extensions for the signcryption scheme and discusses the security in signcryption. The main … contribution to this paper represents the implementation of the signcryption algorithm with the examples provided. …

This article presents two new signcryption schemes. The first one is based on Schnorr digital signature algorithm and … the second one is using Proxy Signature scheme introduced by Mambo. Schnorr Signcryption has been implemented in a program … for Shortened Digital Signature Standard, being part of a new Proxy Signcryption scheme. …
