Abstract: In this paper, we propose the first certificateless multi-proxy signature scheme without pairing. We show our scheme is particularly suitable for practical applications with severely constrained resources due to significant reduction in costs of computation and storage and our scheme is secure against both of the Type I and the Type II adversaries.
