Graph Neural Network Solves Word Problem for Cryptographic Applications

Researchers have developed WPNet, a novel Graph Neural Network designed to heuristically solve the Word Problem for certain non-abelian groups. This model maps unreduced words to dynamic graph structures, clustering algebraically equivalent elements in a continuous embedding space to identify geodesic representatives without discrete reduction steps. A variant of WPNet can predict the geodesic length of words, and has been applied to demonstrate cryptographic vulnerabilities in the Wagner-Magyarik public-key cryptosystem. AI
