Notes on Proxy Signcryption and Multi-proxy Signature Schemes
並列摘要
Proxy signcrytipn scheme allows an original signer to dele- gate his signing power to a proxy such that the latter can signcrypt a message on behalf of the former. Recently, Lin et al. [10, 11] proposed a proxy signcryption with CCA and CMA security. Jin and Wen et al. [8, 12, 13] proposed a multi-proxy signature scheme in certificate-less setting. In this work, we indicate that the Lin et al.'s proxy signcryption scheme does not hold the security of indistinguishability against adaptive chosen-ciphertext attacks and existential unforgeability against adaptive chosen-message attacks. Also, we show that the Jin-Wen's certificateless multi-proxy signature scheme does not hold the security of existential unforgeability against adaptive chosen-message attacks.
