The Zero-Knowledge Witness Was a Strand of DNA
A biochemical construction encoded graph-isomorphism proofs while keeping the hidden node mapping secret.
Summary
A biochemical construction encoded graph-isomorphism proofs while keeping the hidden node mapping secret.
The proposed scheme assigns deliberately orthogonal DNA strands to graph nodes and uses complementary half-linkers to confirm edges through duplex formation. A verifier observes which bindings occur without learning how the two graphs align. Seeded Monte Carlo analysis estimated off-target binding noise small enough to remain an additive correction to the protocol's existing one-half per-round cheating probability. This is a molecular cryptography construction supported by sequence simulation, not evidence of a deployed biochemical security system.
