One might mistake cryptography for a tower built ever higher, but history whispers otherwise: it is the quietest rooms, the ones filled with random noise and no decorative arches, that outlast the grandest halls.
It began in 1977, when the elegant structure of RSA—built on the asymmetry of prime factorization—seemed like the final word in secure communication. But by 1982, the knapsack cryptosystem, once heralded as a breakthrough, was broken wide open by Shamir and Adleman himself, not through brute force, but by exposing the hidden linear structure beneath its design. Cryptographers learned a painful lesson: efficiency through structure invites attack. So they turned to randomness—the McEliece cryptosystem, based on random Goppa codes, survived unbroken for decades, ignored not because it was weak, but because it was too simple to break. Fast forward to 2022: Rainbow, a structured multivariate scheme, was eliminated from NIST’s post-quantum competition not by a quantum computer, but by a desktop PC exploiting its internal symmetries. Now, in 2025, we see the same wisdom resurface—this time in rank-metric codes and the MinRank problem. The new construction avoids masking tricks, rejects algebraic shortcuts, and instead leans on uniformly random instances, just as McEliece did half a century prior. The pattern is unmistakable: every time cryptography is cornered, it escapes not by building higher walls, but by vanishing into the noise.
