Multi-receipt Proxy Signcryption Scheme from Pairings Based on Self-certified Cryptosystem

By merging the theory of proxy signcryption and self-certified signcryption, a multi-receipt proxy signcryption scheme from pairings based on self-certified cryptosystem is constructed.The public key of the user has self-certified characteristic, the system authority (SA) does not require to sign and issue the certificate, simultaneously only the user knows his own private key.The constructed has better security and more practical value than the existing literatures.
