Abstract: Based on the identity-based signcryption, this paper proposed a multi-receiver identity-based proxy signcryption scheme, in which some good characteristics of bilinear pairing are used. The new scheme offers a good solution to the problem of signature with a lot of multi-receiver. Additionally, this scheme which can achieve confidentiality, public verification and high security, was simply designed and easily implemented. Only one pairing computation is needed in it to signcrypt a single message for all receivers. As a result, the efficiency gain of the new scheme is huge especially when there are a large number of recipients.
