Cryptanalysis of a Cryptosystem based on Drinfeld modules

Simon R. Blackburn, Carlos Cid and Steven D. Galbraith

Abstract

A public key cryptosystem based on Drinfeld modules has been proposed by Gillard, Leprevost, Panchishkin and Roblot. The paper shows how an adversary can directly recover a private key using only the public key, and so the cryptosystem is insecure.

Note: Revised version with experimental result.
