Authentication process
Digital signatures using the Diophantine system of equations are implemented. A digital signature is an authentication mechanism that enables the creator of a message to attach a code that acts as a signature. A digital signature scheme typically includes three algorithms: a key generation algorithm, a signing algorithm, and a signature verifying algorithm. The key generation algorithm selects a private key uniformly at random from a set of possible private keys. The key generation algorithm outputs the private key and a corresponding public key. The signing algorithm produces a signature given a message and a private key. The signature verifying algorithm either accepts or rejects a message's claim to authenticity based at least in part on the message, the public key, and the signature.
1. A method programmed in a non-transitory memory of a first device of verifying a digital signature for data, wherein the first device is communicatively coupled to a second device over a network, the method comprising:
receiving the data, the digital signature, and a public key, from the second device over the network, wherein the public key comprises a first set of singular matrices;
generating a hash of the data by the first device, wherein the hash comprises a second set of singular matrices; and
verifying the digital signature by the first device in response to determining that a relation is fulfilled, wherein the relation comprises a combination of a first singular matrix, a matrix and a second singular matrix.
