LISHARK: Lightweight Side Channel Protected Secure Hardware Extension with Re-keying

The Secure Hardware Extension (SHE) provides crucial functionalities such as error-detection, authorization, and authentication of messages exchanged between Electronic Control Units (ECUs) over the Controller Area Network (CAN) bus with the help of Advanced Encryption Standard (AES) cryptographic cores. However, the s...
