一种有效基于身份的门限环签密方案
Efficient identity-based threshold ring signcryption scheme
摘要
Abstract
In order to design an identity-based threshold ring signcryption, this paper presented an efficient identity-based threshold ring signcryption scheme without random oracles by means of secret sharing and bilinear pairing technique, and ana-Iy2ed the security of the scheme. Finally,It proved this scheme satisfied indistinguishability against adaptive chosen ciphertext attacks and existential unforgeability against adaptive chosen message and identity attacks in terms of the hardness of DBDH problem and CDH problem.关键词
