Formally, a message authentication code (MAC) system is a triple of efficient algorithms (G, S, V) satisfying: G (key-generator) gives the key k on input 1 n , where n is the security parameter. S (signing) outputs a tag t on the key k and the input string x .
Description. Message authentication or data origin authentication is an information security property that indicates that a message has not been modified while in transit ( data integrity) and that the receiving party can verify the source of the message. [1] Message authentication does not necessarily include the property of non-repudiation.
In cryptography, an HMAC (sometimes expanded as either keyed-hash message authentication code or hash-based message authentication code) is a specific type of message authentication code (MAC) involving a cryptographic hash function and a secret cryptographic key. As with any MAC, it may be used to simultaneously verify both the data integrity ...
DMARC. Domain-based Message Authentication, Reporting and Conformance ( DMARC) is an email authentication protocol. It is designed to give email domain owners the ability to protect their domain from unauthorized use, commonly known as email spoofing. The purpose and primary outcome of implementing DMARC is to protect a domain from being used ...
Email authentication. Email authentication, or validation, is a collection of techniques aimed at providing verifiable information about the origin of email messages by validating the domain ownership of any message transfer agents (MTA) who participated in transferring and possibly modifying a message. The original base of Internet email ...
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 Secure Hash Algorithms are a family of cryptographic hash functions published by the National Institute of Standards and Technology (NIST) as a U.S. Federal Information Processing Standard (FIPS), including: SHA-0: A retronym applied to the original version of the 160-bit hash function published in 1993 under the name "SHA".
Emergency Action Message. In the United States military's strategic nuclear weapon nuclear command and control (NC2) system, an Emergency Action Message ( EAM) is a preformatted message that directs nuclear-capable forces [1] to execute specific Major Attack Options (MAOs) or Limited Attack Options (LAOs) in a nuclear war.
