原始签密同时提供真实性和隐私性。本文提出了传统公钥密码系统（TPKC）和基于身份的密码系统（IDPKC）之间的高效签密方案。相反，据我们所知，文献中现有的所有签密方案都局限于一种类型的密码系统。我们还讨论了他们在多接收机设置。在随机预言机模型下，在双线性Diffie-Hellman困难问题下，给出了方案的形式化安全性证明。
The primitive signcryption provides authenticity and privacy simultaneously. In this paper, we present efficient signcryption schemes between the traditional public key cryptosystem (TPKC) and the identity based cryptosystem (IDPKC). In contrast, all the existing signcryption schemes available in the literature, to our knowledge, are limited to within one type of cryptosystem. We also discuss them in the multi-receiver setting. Formal security proofs are provided to guarantee the security for our schemes, in the random oracle model, under the hardness of the bilinear Diffie-Hellman problem.
