Certificate-Based Signcryption Scheme for Securing Wireless Communication in Industrial Internet of Things

Abstract

The Industrial Internet of Things (IIoT) community is concerned about the security of wireless communications between interconnected industries and autonomous systems. Providing a cyber-security framework for the IIoT offers a thorough comprehension of the whole spectrum of securing interconnected industries, from the edge to the cloud. Several signcryption schemes based on either identity-based or certificateless configurations are available in the literature to address the IIoT’s security concerns. Due to the identity-based/certificateless nature of the available signcryption schemes, however, issues such as key escrow and partial private key distribution occur. To address these difficulties, we propose a Certificate-Based Signcryption (CBS) solution for IIoT in this article. Hyperelliptic Curve Cryptosystem (HECC), a light-weight version of Elliptic Curve Cryptosystem (ECC), was employed to construct the proposed scheme, which offers security and cost-efficiency. The HECC utilizes 80-bit keys with fewer parameters than the ECC and Bilinear Pairing (BP). The comparison of performance in terms of computation and communication costs reveals that the proposed scheme provides robust security with minimal communication and communication costs. Moreover, we used Automated Validation of Internet Security Protocols and Applications (AVISPA) to assess the security toughness, and the results show that the proposed scheme is secure.
