Abstract
This paper analyzes three identity-based signcryption schemes, attacks the first two schemes using Indistinguishability under Chosen Ciphertext Attack(IND-CPA), attacks the last one using IND-CPA and forgery attacks method and provides improved schemes respectively. Analysis results show that the improved schemes maintain higher efficiency while satisfying confidentiality, unforgeability, nonrepudiation, public verification and forward security.关键词
