New Eidolon signature scheme uses graph coloring to resist quantum attacks

Researchers have introduced Eidolon, a novel post-quantum signature scheme that leverages the NP-complete k-colorability problem. This scheme generalizes existing zero-knowledge protocols and uses Merkle-tree commitments to reduce signature size. Empirical analysis suggests that carefully constructed k-coloring instances can withstand attacks from both classical solvers and graph neural networks, indicating potential resilience against modern cryptanalytic methods.

    Eidolon: A Post-Quantum Signature Scheme Based on k-Colorability in the Age of Graph Neural Networks

    arXiv:2602.02689v2 Announce Type: replace-cross Abstract: We propose Eidolon, a post-quantum signature scheme grounded on the NP-complete k-colorability problem. Our construction generalizes the Goldreich-Micali-Wigderson zero-knowledge protocol to arbitrary k >= 3, applies the F…
