ID-based threshold ring signcryption scheme
摘要
Abstract
An ID-based threshold ring signcryption scheme is proposed.It is based on the concepts of ID-based ring signcryp-tion scheme and threshold signature schetne.The scheme not only has the properties of signcryption: confidentiality and authentication, but also has the properties of ring signcryption and threshold signature.The existential unforgeability against adaptive chosen message attacks is proved to depend on the hardness of CDHP.The indistinguishability against adaptive chosen ci-phertext attacks is proved to depend on the hardness of DBDHP.关键词
