The paper presents a novel concept of processor aimed at symmetric-key cryptographic applications. Its architecture is optimized for implementation of common cryptography tasks. The processor has 128-bit separated data and key registers, dedicated instruction set optimized for key generation and management, embedded cipher, and embedded random number generator. From an architectural point of view,...
The attacker can access the RFID systems illegally because authentication operations on the RFID systems are performed in wireless communication. Authentication methods based on the PUF were presented to defend attacks. Because these utilize Hash and AES, the cost is expensive for the low-cost RFID tag. In this paper, the PUF-based encryption processor and the low-cost RFID authentication protocol...
