一种基于身份的广义签密方案
Identity-based Generalized Signcryption Scheme
摘要
Abstract
Generalized signcryption not only fulfills both the functions of signature and encryption, but also provides confidentiality or authenticity separately under specific inputs.This paper presents an identity-based generalized signcryption scheme based on bilinear pairing, in which three modes are realized through changing input's identities, i.e.signcryption mode, signature-only mode and encryption-only mode.The proposed scheme has improved the drawbacks of receiver verifying signature after decrypting in the traditional signcryption shceme.Anyone can identify the source of the ciphertext without the plaintext.The scheme is safe and also efficient regarding the computation costs after analyzing other schemes.关键词
