Privacy-preserving authentication for general directed graphs in industrial IoT

Achieving trustworthiness, Transferable, Cross-domain Dynamic Accumulator Authentication in Industrial Internet of Things

“…In our scheme, several theoretic definitions also have been based, e.g. Bilinear pairing, Diffie-Hellman Exponent assumption (n-DHE), Strong Diffie-Hellman Problem (n-SDH), Hidden Strong Diffie-Hellman Exponent assumption (n-HSDHE) [16]and a standard digital signature scheme SDS = Gen, Sig, V er [4].…”

“…2. This authentication problem solved in [4] utilizes the transitive authentication relationship between superior and subordinate for a directed tree. However, if node v km wants to access the node v qh , we can see that node v km and node v qh belong to different administrator, that is, in the different administrator domain.…”

“…Since the accumulator add computation, accumulator up-to-date computation and accumulator witness up-to-date operation dominate the computational overhead, we only focus on these operations following estimation. Table I shows computation complexity analysis on the maximum computation cost of one member during the execution between our protocol and literature [4]. In order to easily…”

“…However, the industrial Internet of Things (IIoT) offered interconnection and intelligence to industrial systems through sensing devices and actuators has the potential to change the world as the Internet did [3]. In practice IIoT system, for the purpose of protecting the legitimate access each device has its own unique identity and has the capability to sense, compute, authenticate and communicate [4] [5]. Many existing solutions have been introduced into security and privacy solutions in IIoT, e.g., the data security, wireless power transfer, and the deployment and communication problems of devices [6] [7].…”

“…In a multi-layer distributed IIoT system, the following situations are often encountered: on the one hand the supervisor entity A wants to command the subordinate entity B, A should provide a legal authoritative signature to show the legality of its command [4]; On the other hand, entity A wants to access subordinate entity C of entity B who is in the same regulatory authority as A, A also should provide a legal authoritative signature to illustrate the legality of its command. In this paper, vertices and edges are used to represent company members and the authentication relationship between them, respectively.…”
