EFFICIENT HYBRIDIZATION OF CLASSICAL AND POST-QUANTUM SIGNATURES

Abstract:

In one example an apparatus comprises verification circuitry to receive, in a RSA/ECDSA processor, an input message, compute, in the RSA/ECDSA processor, a hash digest (d) for the message, and provide the hash digest as an input to a XMSS/LMS processor. Other examples may be described.
