PUFs are an emerging security primitive that offers a lightweight security alternative to highly constrained devices like RFIDs. PUFs used in authentication protocols however suffer from unreliable outputs. This hinders their scaling, which is necessary for increased security, and makes them also problematic to use with cryptographic functions. We introduce a new Dual Arbiter PUF design that reveals additional information concerning the stability of the outputs. We then employ a novel filtering scheme that discards unreliable outputs with a minimum number of evaluations, greatly reducing the BER of the PUF.

NoCs are a well established research topic and several Implementations have been proposed for Self-healing. Self-healing refers to the ability of a system to detect faults or failures and fix them through healing or repairing. The main problems in current self-healing approaches are area overhead and scalability for complex structure since they are based on redundancy and spare blocks. Also, faulty router can isolate PE from other router nodes which can reduce the overall performance of the system. This paper presents a self-healing for a router to avoid denied fault PE function and isolation PE from other nodes. In the proposed design, the neighbor routers receive signal from a faulty router which keeps them to send the data packet which has only faulted router destination to a faulty router. Control unite turns on switches to connect four input ports to local ports successively to send coming packets to PE. The reliability of the proposed technique is studied and compared to conventional system with different failure rates. This approach is capable of healing 50% of the router. The area overhead is 14% for the proposed approach which is much lower compared to other approaches using redundancy.
