An Energy-Efficient Reconfigurable DTLS Cryptographic Engine for End-to-End Security in IoT Applications
This provides a solution for IoT applications requiring secure communication with significant energy and code efficiency improvements, though it is incremental as it builds on existing DTLS and hardware methods.
The paper tackled the problem of enabling end-to-end security for IoT by presenting a reconfigurable cryptographic engine implementing the DTLS protocol, achieving a 10x reduction in code size and 438x improvement in energy-efficiency over software, with ECC primitives showing 237x and 9x energy savings compared to software and state-of-the-art hardware, respectively.
This paper presents a reconfigurable cryptographic engine that implements the DTLS protocol to enable end-to-end security for IoT. This implementation of the DTLS engine demonstrates 10x reduction in code size and 438x improvement in energy-efficiency over software. Our ECC primitive is 237x and 9x more energy-efficient compared to software and state-of-the-art hardware respectively. Pairing the DTLS engine with an on-chip RISC-V allows us to demonstrate applications beyond DTLS with up to 2 orders of magnitude energy savings.
