elliptic curve cryptography, side channel attacks
LadderLeak is a new attack that exploits side channels present in ECDSA, claiming to allow real-world breaking of ECDSA with less than a bit of nonce leakage. But what does “less than a bit” mean in this context? Is LadderLeak really that effective at breaking ECDSA, with so little information to go on? Joining us this episode are LadderLeak co-authors Akira Takahashi, Mehdi Tibouchi and Yuval Yarom to discuss these questions and more.
