可实现隐私保护的多接收者异构聚合签密方案
Privacy-preserving multi-recipient aggregate signcryption for heterogeneous cryptography systems
摘要
Abstract
Taking into account the secure communication and privacy protection in heterogeneous cryptography systems,we propose a heterogeneous aggregate signcryption scheme from certificateless cryptosystems to identity-based cryptography systems,which allows multiple senders to communicate securely with multiple recipients.The scheme makes the senders anonymous in the system,and only trust agencies can track the senders' real information.For the receivers,the disclosure of the legitimate recipients' user information to unauthorized users is prevented by applying the Lagrange interpolation formula.In the random oracle model,it is proved that the scheme possesses indistinguishability against adaptive chosen ciphertext attacks and existential unforgeability against adaptive chosen-message attacks.Experimental results show that the scheme effectively improves the computational efficiency of the system.关键词
