签密是由郑提出的，是一种密码原语，它同时完成了数字签名和加密的功能，并以更有效的方式保证了机密性、完整性和不可否认性。针对不同的应用，提出了基于身份的密码体制中的无证书签密和代理签密。这些方案大多是由椭圆曲线上的双线性对构造的。然而，最近提出的一些方案没有配对。本文提出了一种无双线性对的无证书代理身份签密方案，该方案是高效和安全的。
Signcryption, which was introduced by ZHENG, is a cryptographic primitive that fulfils the functions of both digital signature and encryption and guarantees confidentiality, integrity and non-repudiation in a more efficient way. Certificateless signcryption and proxy signcryption in identity-based cryptography were proposed for different applications. Most of these schemes are constructed by bilinear pairings from elliptic curves. However, some schemes were recently presented without pairings. In this paper, we present a certificateless proxy identity-based signcryption scheme without bilinear pairings, which is efficient and secure.
