A New Multi-Receiver ID-Based Anonymous Signcryption
Pang Liao · Chinese Journal of Computers · 2011
Aiming at the receiver privacy exposure and de-signcryption unfairness problems that exist in the existing multi-receiver ID-based signcryption schemes,a fair multi-receiver ID-based anonymous signcryption scheme is proposed.The Lagrange interpolating polynomial is adopted to achieve the anonymity,which can not only solve the problem that the existing schemes cannot protect the privacy of receivers,but also meet the fairness of de-signcryption so that it can prevent the possible cheating behavior of the sender effectively.Finally,the proof of correctness and security is provided in details,and the performance comparison between the proposed scheme and other correlative schemes are given in succession.Analysis results show that this scheme is a secure and effective signcryption scheme and it can be used to broadcast sensitive information in unsafe and open network environment.
