A multi-receiver identity-based signcryption
Chen Qi-feng · Computers & Security · 2009
Based on the identity-based signcryption,this paper proposed a multi 一 receiver identity- based signcryption scheme,in which some good characteristics of bilinear pairing are used.The new scheme offers a good solution to the problem of signcryption with a lot of muiti- receiver. Additionally,this scheme which can achieve confidentiality,public verification and high security.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 especiaily when there are a large number of recipients.
