A Proxy signature scheme enables a proxy signer to sign a message on behalf of the original signer. In this paper, we propose efficient and secure Proxy multi-signature scheme based on elliptic curve cryptosystem. Our scheme satisfy all the proxy requirements and require only elliptic curve multiplication and elliptic curve addition which needs less computation overhead compared to modular exponentiation also our scheme is withstand against original signer forgery and public key substitution attack. © 2012 Springer-Verlag.
