Message authentication code. In cryptography, a message authentication code ( MAC ), sometimes known as an authentication tag, is a short piece of information used for authenticating and integrity -checking a message. In other words, to confirm that the message came from the stated sender (its authenticity) and has not been changed (its integrity).
Serge Massar was born in Zambia in 1970. [2] He obtained a degree in physics, then a PhD from the Université libre de Bruxelles (ULB) in 1991 and 1995, respectively. [2] He completed his post-doctoral research at Tel Aviv University from 1995 to 1997, and subsequently at Utrecht University from 1997 to 1998. [2] [3]
Anything In Anything (AYIYA) is a computer networking protocol for managing IP tunneling protocols in use between separated Internet Protocol networks. It is most often used to provide IPv6 transit over an IPv4 network link when network address translation masquerades a private network with a single IP address that may change frequently because of DHCP provisioning by Internet service providers.
Multi-factor authentication ( MFA; two-factor authentication, or 2FA, along with similar terms) is an electronic authentication method in which a user is granted access to a website or application only after successfully presenting two or more pieces of evidence (or factors) to an authentication mechanism. MFA protects personal data —which ...
Authenticated Encryption (AE) is an encryption scheme which simultaneously assures the data confidentiality (also known as privacy: the encrypted message is impossible to understand without the knowledge of a secret key) and authenticity (in other words, it is unforgeable: the encrypted message includes an authentication tag that the sender can calculate only while possessing the secret key).
Bashar Al Masri (/ Arabic: بشار مصري / February 3, 1961) is a Palestinian businessman. He is the founder and chairman of Massar International since its establishment in 1994. He is the founder of Rawabi, Palestine's first planned city, and the founder and the CEO of Bayti Real Estate Investment Company that built the city. [1]
The message authentication code, also known as digital authenticator, is used as an integrity check based on a secret key shared by two parties to authenticate information transmitted between them. [4] It is based on using a cryptographic hash or symmetric encryption algorithm. [5] The authentication key is only shared by exactly two parties (e ...
Authenticator. An authenticator is a means used to confirm a user's identity, [1] [2] that is, to perform digital authentication. A person authenticates to a computer system or application by demonstrating that he or she has possession and control of an authenticator. [3] [4] In the simplest case, the authenticator is a common password .
