摘要

The Industrial Internet of Things (IIoT) involves the real-time gathering of information from physical devices and technologies for improved perception and management. To ensure information transmission security, an efficient and secure cryptography scheme is needed, especially for devices under resource constraints. In this paper, a heterogeneous signcryption (HSC) scheme is designed to meet security requirements in the IIoT environment. This construction employs a heterogeneous system, with the sender using certificateless cryptography (CLC) to effectively solve the key escrow problem in identity-based cryptography (IBC) and the certificate management problem in public key infrastructure (PKI). The receiver, on the other hand, uses IBC to settle the certificate management issue in PKI. The scheme supports formal security proof in the random oracle model (ROM). Furthermore, the detailed performance analysis demonstrates that the scheme has advantages in terms of energy consumption and computation overhead, making it suitable for the IIoT environment.
