1. An apparatus, comprising:
processing circuitry to perform operations comprising at least one of:
generate a signature to be transmitted in association with a message, the processing circuitry to apply a hash-based signature scheme to the message using a private key to generate the signature comprising a public key, or
verify a signature received in association with the message, the processing circuitry to apply the hash-based signature scheme to verify the signature using the public key;
divide the signature into a plurality of signature components; and
apply a secure hash algorithm (SHA) to the plurality of signature components; and
an accelerator circuitry to:
apply a structured order to at least one set of inputs to the hash-based signature scheme;
identify a hash chain message length for each signature component in the plurality of signature components; and
sort the plurality of signature components into an indexed hash chain list according to the respective hash chain message length of each signature component in the plurality of signature components.
