Signatures with efficient protocols are a form of digital signature invented by Jan Camenisch and Anna Lysyanskaya in 2001. In addition to being secure digital signatures, they need to allow for the efficient implementation of two protocols: A protocol for computing a digital signature in a secure two-party computation protocol. A protocol for ...
G2A.COM’s main offerings are game key codes for platforms such as Steam, EA app, Uplay, PlayStation Network, Xbox, and Nintendo Switch, as well as gift cards, top-ups, and other digital products. [5] As a marketplace, G2A.COM does not sell any digital items itself. Instead, the platform is an intermediary between buyers and sellers.
Definition. 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 algorithm outputs the private key and a corresponding public key. A signing algorithm that, given a message and a private key, produces a signature.
Electronic authentication. Electronic authentication is the process of establishing confidence in user identities electronically presented to an information system. [ 1] Digital authentication, or e-authentication, may be used synonymously when referring to the authentication process that confirms or certifies a person's identity and works.
The Electronic Signatures in Global and National Commerce Act (ESIGN, Pub. L. Tooltip Public Law (United States) 106–229 (text), 114 Stat. 464, enacted June 30, 2000, 15 U.S.C. ch. 96) is a United States federal law, passed by the U.S. Congress to facilitate the use of electronic records and electronic signatures in interstate and foreign commerce.
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. In a public-key cryptosystem, two keys are generated: data can only be encrypted with the public key and encrypted ...
The qualified electronic signature is one such standard that has been outlined under eIDAS. [3] [4] A qualified electronic signature is an advanced electronic signature with a qualified digital certificate that has been created by a qualified signature creation device (QSCD). For an electronic signature to be considered as a qualified ...
Certificate signing request. In public key infrastructure (PKI) systems, a certificate signing request ( CSR or certification request) is a message sent from an applicant to a certificate authority of the public key infrastructure (PKI) in order to apply for a digital identity certificate. The CSR usually contains the public key for which the ...
