Abstract
According to the distribution of IoT nodes and the characteristics of information transmission, the traditional cross-domain signature scheme cannot meet the requirements of real-time information confidentiality in the IoT. Based on this, this paper proposes a cross-domain based on CLPKC and IDPKC. Signcryption authentication mechanism, which is based on the computational Diffie–Hellman problem (CDHP, Computational Diffie–Hellman problem) and the modification of Diffie–Hellman (mICDH, modification Inverse Computational Diffie–Hellman) under the random oracle model Under the assumption of the problem, the scheme satisfies confidentiality, is not styling and anonymity. The scheme has a fast computing speed, realizes fast identity authentication under the premise of satisfying data confidentiality, and supports different encryption system environments in which the communication parties are located, which is more suitable for the actual communication characteristics of the IoT environment.
