Abstract

A logic circuitry package includes an interface to communicate with a host and a logic circuit. The logic circuit includes a memory arrangement storing digital signature metadata to facilitate verification of associated signed data. The digital signature metadata includes a schema identifier field storing a schema version number; a key identifier field storing an identifier of a signing key; a plurality of data block address fields, each storing an address corresponding to a data block of a plurality of data blocks over which a digital signature is originally computed; and a plurality of data block length fields corresponding to the plurality of data blocks, each data block length field storing data indicating a length of the corresponding data block. The logic circuit is configured to receive a read request from the host and transmit the digital signature metadata to the host in response to the read request.
