Unclonable Polymers and Their Cryptographic Applications
summary
Claim: a biologically grounded primitive—consumable token—encodes secrets in short peptides (≈30 amino acids, keys ≈10 amino acids ≈50 bits) with an antibody header that lets a holder purify a macroscopic sample for a single mass‑spec read that destroys the vial; adversaries get at most n constant reads. Tools: peptide synthesis, antibody pull‑down, mass spectrometry, error‑correcting secret sharing, iO and one‑way functions. Outcome: lab prototype vials are synthesized but not yet mass‑spec read; constructions yield a digital locker and a 1,n‑time program variant after amplification.
