基于身份多接收者签密双线性对方案
An efficient identity-based multi-recipient signcryption scheme
摘要
Abstract
Identity-based multi-recipient signcryption (ID-MRSC) is an extension of identity-based signcryption.It enables a user to broadcast a message to multiple receivers in a confidential and authenticated way.The definition and the security model of ID-MRSC was presented. The ID-MRSC scheme was secure against adaptively chosen ciphertext and identity attack in the random oracle model.The ID-MRSC scheme meets the requirements of signature unforgeability,forward security and public verifiability.Furthermore,it is significantly more efficient than currently available identity-based signcryption schemes,which have to re-signcrypt and re-send a message multiple times when involving multiple recipients with respect to computational costs and communication overheads.关键词
