1. An apparatus, comprising:

  • a computer readable memory to store a public key associated with a signing device;

    communication logic to receive, from the signing device, a signature chunk which is a component of a signature generated by a hash-based signature algorithm, and at least a first intermediate node value associated with the signature chunk;

    verification logic to;

    execute a first hash chain beginning with the signature chunk to produce at least a first computed intermediate node value;

    execute a second hash chain beginning with the at least one intermediate node value associated with the signature chunk to produce a first computed final node value; and

    use the first computed intermediate node value and the first computed final computed node value to validate the signature generated by the hash-based signature algorithm.
