Abstract
Digital signatures are generated for a message using an authentication tree data structure in which nodes are created as needed from a root node. A public and secret key pair is generated using a one-time signature method to form each node, and the secret key of each parent node is used to sign the public keys of its child nodes. Once the secret key of a node has been used in creating a signature for a message, it may be revealed. The signature data structure is unbounded and stateless, and need not be pre-generated and fixed.
