Secure and efficient communication approaches for Industry 5.0 in edge computing

With the rapid development of the new generation of information technology and the deep integration with industry, Industry 5.0 systematically puts forward the consumer-centric industrial production core, and emphasizes the sustainable and resilient technologies. Industry 5.0 considers the development of industry not only from the technical aspect, but also from the economic, social and environmental aspects, and studies how to use technological innovation to support the production of consumer electronics. In order to achieve interconnection, collaboration and sustainable communication, the integration of Industry 5.0 and edge computing not only reduces the computing bottleneck and communication bottleneck, but also reduces the delay, which helps to transform the industrial process model from centralized to distributed. However, a large number of privacy sensitive data in Industry 5.0 need to interact through the network, which also makes it possible for malicious network attackers to take advantage of it. Therefore, this paper proposes a secure and effective communication approach based on edge computing in Industry 5.0. This approach introduces three-factor authentication and elliptic curve cryptography to ensure the anonymity, confidentiality and integrity of the message. Based on the security proof, the proposed approach meets the security requirements. Through performance analysis, compared with other related schemes, this approach provides better security, and has obvious advantages in computation and communication efficiency.
