中文摘要:
      为保障异构环境网络通信安全,借鉴异构签密和数字签名思想,首先提出异构数字签名的概念,然后基于双线性Diffie-Hellman困难问题,提出安全的公钥基础设施PKI与基于身份加密IBC之间的双向异构数字签名方案。该方案支持正确性、不可伪造性和不可否认性。基于双线性Diffie-Hellman困难问题和随机预言机模型,提出不可伪造性的安全证明模型。该模型包含初始化参数阶段、询问阶段和伪造阶段。基于此模型,证明了提出方案的不可伪造性。最后,对性能进行了分析,结果表明,提出方案的计算量少。此外,发现文献[24]中方案的正确性和不可传递性证明存在错误。
英文摘要:
      In order to protect the security of heterogeneous environment communication, borrow the idea from heterogeneous signcryption and digital signature, firstly, we propose the concept of heterogeneous digital signature, and then, based on the Bilinear Diffie-Hellman difficult problem, present a secure mutual heterogeneous digital signature scheme between public key infrastructure PKI and identity-based cryptography IBC, which supports correctness, unforgeability and non-repudiation. In addition, based on Bilinear Diffie-Hellman difficult problem and random oracle model, propose a security model of unforgeability analysis, which consists of three phases: setup, query, forge. Under this model, we prove that the proposed scheme meet unforgeability. At last, we analyze efficiency, and the result shows that the efficiency is better. Furthermore, we found that there are some errors in proving correctness and non-transferability in the scheme in reference [24].
