Blind signature schemes see a great deal of use in applications where sender privacy is important. This includes various "digital cash" schemes and voting protocols.For example, the integrity of some electronic voting system may require that each ballot be certified by an election authority before it can be accepted for counting; this allows the authority to check the credentials of the voter ...
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.
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 ...
The procedure for capturing a fingerprint using a sensor consists of rolling or touching with the finger onto a sensing area, which according to the physical principle in use (optical, ultrasonic, capacitive, or thermal – see § Fingerprint sensors) captures the difference between valleys and ridges. When a finger touches or rolls onto a ...
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.
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.
