Novel Key Recovery Attack on Secure ECDSA Implementation by Exploiting Collisions between Unknown Entries
In this paper, we propose a novel key recovery attack against secure ECDSA signature generation employing regular table-based scalar multiplication. Our attack exploits novel leakage, denoted by collision information, which can be constructed by iteratively determining whether two entries loaded fro...
