Dynamic Multiparty Authentication using Cryptographic Hardware for the Internet of Things

The rapid development of various emerging technologies such as cloud computing and the Internet of Things (IoT) presents significant security and privacy challenges. In particular, complex and challenging applications involving various business parties have the requirement to delegate access control mechanisms securely to one or more parties, who in turn can govern methods that enable multiple other parties to be authenticated in relation to the services that they wish to consume. Moreover, modern integrated design and manufacturing follows a business model where different third-party vendors provide hardware, software, and manufacturing services, making it hard to ensure the trustworthiness of the entire process. The emergence of IoT has led to our use of Field Programmable Gate Array (FPGA) devices with Dynamic Partial Reconfiguration (DPR) abilities, which allows for modifications to the hardware implemented to undergo changes and incorporate dynamic addition/deletion of access using security protocols. We use, Physically Unclonable Functions (PUF), cryptographic hardware primitive which are based on a physical system having easy to evaluate, hard to predict and manufacturer resistant properties in developing a security protocol. In this paper, we combine the concepts of hardware security through PUFs and hardware evolution through DPR in providing dynamic secure multiparty authentication system.
