Output-sensitive Information flow analysis [PDF]
Logical Methods in Computer Science, 2021 Constant-time programming is a countermeasure to prevent cache based attacks where programs should not perform memory accesses that depend on secrets. In some cases this policy can be safely relaxed if one can prove that the program does not leak more ...

System-level Non-interference for Constant-time Cryptography [PDF]
, 2014 International audienceCache-based attacks are a class of side-channel attacks that are particularly effective in virtualized or cloud-based en-vironments, where they have been used to recover secret keys from cryptographic implementations.

Finding Small and Large
IEEE Transactions on Quantum Engineering, 2020 Algorithms for triangle finding, the smallest nontrivial instance of the k-clique problem, have been proposed for quantum computers. Still, those algorithms assume the use of fixed access time quantum RAM.

An Efficient Speedup Strategy for Constant Sum Game Computations [PDF]
Informatică economică, 2014 Large classes of game theoretic problems seem to defy attempts of finding polynomial-time al-gorithms while analyzing large amounts of data. This premise leads naturally to the possibility of using efficient parallel computing implementations when ...

Fast and Secure Implementation of Modular Exponentiation for Mitigating Fine-Grained Cache Attacks
Applied Sciences, 2018 Constant-time technique is of crucial importance to prevent secrets of cryptographic algorithms from leakage by cache attacks. In this paper, we propose Permute-Scatter-Gather, a novel constant-time method for the modular exponentiation that is used in ...
