Abstract

As various applications of ad hoc networks have been proposed, security has become an important research issue. ID-based signcryption is very suitable to provide security solution for ad hoc networks. In multi-domain ad hoc networks, we should use identity-based sign cryption with multiple private key generators. Recently, two such schemes were proposed. However, we find that both schemes are not secure. In this paper, we propose a new identity-based sign cryption with multiple private key generators. We prove its semantic security and existential unforgeability in the random oracle model. Compared with the existing two schemes, our scheme is more secure and efficient.
