On the Insecurity of Parallel Repetition for Leakage Resilience
A fundamental question in leakage-resilient cryptography is: can leakage resilience always be amplified by parallel repetition? It is natural to expect that if we have a leakage-r...

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...

A Leakage-Resilient Mode of Operation
A weak pseudorandom function (wPRF) is a cryptographic primitive similar to ? but weaker than ? a pseudorandom function: for wPRFs one only requires that the output is pseudorandom...

An Improvement on a Three-party Password-based Key Exchange Protocol Using Weil Pairing
The three-party password-based key exchange protocols using Weil pairing proposed by Wen is vulnerable to impersonation attack. By introducing hard artificial intelligence problem...
