What is Merkles Tree Signature Scheme?
Submitted by: AdministratorMerkle proposed a digital signature scheme that was based on both one-time signatures and a hash function and that provides an infinite tree of one-time signatures.
One-time signatures normally require the publishing of large amounts of data to authenticate many messages, since each signature can only be used once. Merkle's scheme solves the problem by implementing the signatures via a tree-like scheme. Each message to be signed corresponds a node in a tree, with each node consisting of the verification parameters that are used to sign a message and to authenticate the verification parameters of subsequent nodes. Although the number of messages that can be signed is limited by the size of the tree, the tree can be made arbitrarily large. Merkle's signature scheme is fairly efficient, since it requires only the application of hash functions.
