Abstract
A method comprises receiving an image of an update for a software module, a rate parameter, an index parameter, and a public key, generating a 32-byte aligned string, computing a state parameter using the 32-byte aligned string, generating a modified message representative, computing a Merkle Tree root node, and in response to a determination that the Merkle Tree root node matches the public key, forwarding, to a remote device, the image of the update for a software module, the state parameter; and the modified message representative.
