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.
