When was hash chain first used?

$begingroup$


Hash linking is used to prove the integrity of a blockchain, or similar systems. When was that technique first used? I would guess it was early, maybe 1950s/1960s?

          Lamport suggested the use of hash chaining in 1981 in Password Authentication with Insecure Communication, Communications of the ACM 24.11 (November 1981), pp 770-772.



          He cites 3 prior papers:




          1. Diffie, W., and Hellman, M.E. New directions in cryptography.
            IEEE Trans. Inform. Theory 1T-22 (Nov. 1976), 644-654.


          2. Evans, A., Kantrowitz, W., and Weiss, E. A user authentication
            scheme not requiring secrecy in the computer. Comm. A CM 17, 8
            (Aug. 1974), 437-442.


          3. Wilkes, M.V. Time-Sharing Computer Systems. American
            Elsevier, New York, 1972.



          [1] is the paper which essentially invented Public Key Cryptography in the open literature. Lamport refers to the use of a one way function F, as described there, as hash functions in his chain.



          [2] and [3] are cited for "the widespread use of such a function", e.g., storing $y=F(x)$ instead of $x$.



          So it seems to me Lamport may well be the first to suggest the use hash chaining.



          Edit: Thanks to @Gilles for pointing out Merkle patented hash trees in 1979.

            Merkle patented hash trees in 1979, and hash chains are a special case of that. I don't know if that special case had been used before.
