An electronic signature, or e-signature, is data that is logically associated with other data and which is used by the signatory to sign the associated data. [1] [2] [3] This type of signature has the same legal standing as a handwritten signature as long as it adheres to the requirements of the specific regulation under which it was created (e.g., eIDAS in the European Union, NIST-DSS in the ...
A digital signature scheme typically consists of three algorithms: A key generation algorithm that selects a private key uniformly at random from a set of possible private keys.
The following QR barcode is attached to a computer or smartphone to prove it belongs to a specific person. It uses a b type field, described above, to contain a secure personal identification number [PIN] remembered by the owner of the device. The DigSig Verifier will ask for the PIN to be entered, before the verification can take place.
The Digital Signature Algorithm (DSA) is a public-key cryptosystem and Federal Information Processing Standard for digital signatures, based on the mathematical concept of modular exponentiation and the discrete logarithm problem.
Parameter; CURVE: the elliptic curve field and equation used G: elliptic curve base point, a point on the curve that generates a subgroup of large prime order n: n: integer order of G, means that =, where is the identity element.

In cryptography, a ring signature is a type of digital signature that can be performed by any member of a set of users that each have keys.Therefore, a message signed with a ring signature is endorsed by someone in a particular set of people.
