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.
Claims9
An apparatus comprising:
- processor circuitry coupled to a memory, the processor circuitry to:
- compute a message representative using a state parameter based on an aligned string, wherein the aligned string is generated based on one or more of an index parameter or a key;
- concatenate the message representative to generate a modified message representative;
- associate the modified message representative to one or more software updates;
- and
- communicate the modified message representative to a remote computing device.
A method comprising:
- computing a message representative using a state parameter based on an aligned string, wherein the aligned string is generated based on one or more of an index parameter or a key;
- concatenating the message representative to generate a modified message representative;
- associate the modified message representative to one or more software updates;
- and
- communicate the modified message representative to a remote computing device.
A non-transitory computer-readable medium having stored thereon instructions which, when executed, cause a computing device to perform operations comprising:
- computing a message representative using a state parameter based on an aligned string, wherein the aligned string is generated based on one or more of an index parameter or a key;
- concatenating the message representative to generate a modified message representative;
- associate the modified message representative to one or more software updates;
- and
- communicate the modified message representative to a remote computing device.
