A Method to Solve Cyclotomic Norm Equations
We present a technique to recover f ∈ Q(ζp) where ζp is a primitive pth root of unity for a prime p, given its norm g = f ∗ ¯f in the totally real field Q(ζp + ζ−1 p )....

Defeating Countermeasures Based on Randomized BSD Representations
Abstract. The recent development of side channel attacks has lead implementers to use increasingly sophisticated countermeasures in critical operations such as modular exponentiati...

Attacking Unbalanced RSA-CRT Using SPA
Abstract. Efficient implementations of RSA on computationally limited devices, such as smartcards, often use the CRT technique in combination with Garner’s algorithm in order to ...

Polynomial Fairness and Liveness
Important properties of many protocols are liveness or availability, i.e., that something good happens now and then. In asynchronous scenarios these properties obviously depend on...

Cryptographic Protocol Synthesis and Verification for Multiparty Sessions
We present the design and implementation of a compiler that, given high-level multiparty session descriptions, generates custom cryptographic protocols. Our sessions specify pre-a...
