Security for signcryption : the multi-user model

Abstract

This chapter presents security models for confidentiality and unforgeability of signcryption schemes in the multi-user setting. A family of security models for signcryption in both two-user and multi-user settings was presented by An et al. [10] in their work on signcryption schemes built from black-box signature and encryption schemes—see Chap. 2.11 page(s
