Vulnerability Bounds and Leakage Resilience of Blinded Cryptography under Timing Attacks
—We establish formal bounds for the number of min-entropy bits that can be extracted in a timing attack against a cryptosystem that is protected by blinding, the state-of-the art...

Leakage-Resilient Cryptography
We construct a stream-cipher SC whose implementation is secure even if a bounded amount of arbitrary (adaptively, adversarially chosen) information about the internal state of SC ...

Leakage-Resilient Signatures
The strongest standard security notion for digital signature schemes is unforgeability under chosen message attacks. In practice, however, this notion can be insufficient due to â€...

Securing Computation against Continuous Leakage
We present a general method to compile any cryptographic algorithm into one which resists side channel attacks of the only computation leaks information variety for an unbounded nu...

The Leakage-Resilience Limit of a Computational Problem Is Equal to Its Unpredictability Entropy
A cryptographic assumption is the (unproven) mathematical statement that a certain computational problem (e.g. factoring integers) is computationally hard. The leakage-resilience l...
