AES Datapath Optimization Strategies for Low-power Low-Energy Multisecurity-level Internet-of-Thing Applications
This project plays vital role in all type of communication applications. The security can be enhanced by using standardized and proven-secure block ciphers as advanced encryption standard (AES) for data encryption and authentication. However, these security functions take a large amount of processing power and power/energy consumption. In this paper, we present our hardware optimization strategies for AES for high-speed ultralow-power ultralow-energy IoT applications with multiple levels of security. This project includes a novel low-transition linear feedback shift register (LFSR) that is based on some new observations about the output sequence of a conventional LFSR. Security of a hardware implementation can be compromised by a random fault or a deliberate attack. BIST introduction plays important role in finding errors in any operation.
