Paper 2003/209
Using the Trace Operator to repair the Polynomial Reconstruction based Cryptosystem presented at Eurocrypt 2003
Daniel Augot and Matthieu Finiasz and Pierre Loidreau
Abstract
In this paper, we present a modification of the Augot-Finiasz cryptosystem presented at EUROCRYPT 2003. Coron managed to design an attack against the original cryptosystem enabling an attacker to decrypt any intercepted ciphertext efficiently. We introduce here a modification of the scheme which appears to resist to this attack. We furthermore propose parameters thwarting the state of the art attacks.
