The Walnut Digital Signature Algorithm (WalnutDSA) brings together methods in group theory, representation theory, and number theory, to yield a public-key method that provides a means for messages to be signed and signatures to be verified, on platforms where traditional approaches cannot be executed. After briefly reviewing the various heuristic/practical attacks that have be posited by Hart et al, Beullens-Blackburn, Kotov-Menshov-Ushakov, and Merz-Petit, we detail the parameter choices that…

This paper shows that this structure can be exploited to launch several practical attacks against the Walnut cryptosystem, which relies on a one-way function called E-Multiplication, which has a rich algebraic structure.

### An attack on the Walnut digital signature algorithm

A heuristic algorithm is presented that allows a passive eavesdropper to recover a substitute for the signer’s private key by removing cloaking elements and then solving a system of conjugacy equations in braids.

The new technique greatly extends the reach of practical attacks, providing the most cost-effective means known to date for defeating: the small subgroup used in certain schemes based on discrete logarithms such as Schnorr, DSA, and elliptic curve cryptosystems; hash functions; and double encryption and three-key triple encryption.

Experimental evidence is provided that under certain conditions parts of the Garside normal form of factors can be found in the GARSidenormal form of their product and this observation can be exploited to decompose products of braids of the form ABC when only B is known.
