J. Malone-Lee, Signcryption with Non-Interactive Non-Repudiation. CSTR-02-004, Department of Computer Science, University of Bristol. May 2004. PDF, 223 Kbytes.


Signcryption is a public-key cryptographic primitive that combines the functionality of a digital signature scheme and a public-key encryption scheme. We propose a model of security for signcryption schemes that offer non-interactive non-repudiation. In addition we propose a scheme and give a full analysis in this model.
