"A hash chain is the successive application of a cryptographic hash function to a piece of data. In computer security, a hash chain is a method to produce many one-time keys from a single key or password. For non-repudiation a hash function can be applied successively to additional pieces of data in order to … See more A hash chain is a successive application of a cryptographic hash function $${\displaystyle h}$$ to a string $${\displaystyle x}$$. For example, See more Winternitz chains (also known as function chains ) are used in hash-based cryptography. The chain is parameterized by the Winternitz … See more A hash chain is similar to a blockchain, as they both utilize a cryptographic hash function for creating a link between two nodes. However, a blockchain (as used by Bitcoin and related systems) is generally intended to support distributed agreement around a public … See more Leslie Lamport suggested the use of hash chains as a password protection scheme in an insecure environment. A server which needs to … See more Binary hash chains are commonly used in association with a hash tree. A binary hash chain takes two hash values as inputs, concatenates them and applies a hash function to the result, thereby producing a third hash value.
