Abstract
In order to improve communication efficiency and reduce the lost brought by key leakage as much as possible, this paper proposes a novel certificateless multi-proxy signcryption scheme with forward security based on the certificateless cryptography and the ideas of the latest signcryption key. In our proposed scheme, even if the proxy key got lost, attacker could not forge the signcryption key. In the meantime, the proposed scheme can effectively prevent public key replacement and malicious-but-passive KGC（key generation centre）attack. Our paper finally proved that the proposed scheme has decent security, communication efficiency and desirable practicality.
