A post quantum secure multi-party collaborative signature with deterability in the Industrial Internet of Things

Industrial Internet-of-Things (IIoT for short) which is the basis of Industry 4.0, extends Internet connectivity beyond traditional computing devices, for example, smartphones, computers, laptops, webcams, etc., to the physical world for improving accuracy and efficiency while reducing the production cost. However, there exists large numbers of security threats, such as data leakage and privacy threats. To solve these issues, we first present a system model, security requirements and then proposed a post quantum secure multi-party collaborative signature with deterability in the IIoT environment. In this scheme, formal security proofs are given in the random oracle assuming that AMLWE and AMSIS problem are hard. We also demonstrate the potential utility of our proposed scheme by evaluating its performance.
