(communications)
Security measure designed to establish the authenticity of a message by means of an authenticator within the transmission derived from certain predetermined elements of the message itself.

A common approach to doing this involves generating a tag (commonly called a Message Authentication Code, or MAC) that depends, in a complex way, on all the bits in the message body.

This Sony-based Smartrac BullsEye tag provides 224 bytes of user memory and an enhanced security feature that enables mutual authentication by message authentication code (MAC), making it suited for all typical non-payment NFC applications.
To achieve both message authentication and anonymity, Raya and Hubaux in (M.
Iyenger said that Conceal works by 'wrapping' whatever data is written to a smartphone's SD card in a layer of cryptography, using subset of cryptographic algorithms and AES to generate a Message Authentication Code to validate the data package and validate that it hasn't been tampered with.
Sterilization is the immediate destruction of system crypto, COMSEC, TRANSEC, hope set and message authentication key variables, followed by the arming fuse being blown and the batteries drained.
2 into SharkSSL, Real Time Logic implements the stronger cryptographic algorithm, improved encryption, and superior message authentication proven to secure TCP/IP communications at the enterprise level into the small, resource-constrained footprint of an embedded device.
DMARC (Domain-based Message Authentication, Reporting & Conformance) is a technical specification intended to standardise how email recipient systems authenticate incoming messages using the SPF and DKIM technologies.
16] provided a better version that incorporated two improvements: (1) the secret image can be reconstructed completely by using GF(28) instead of GF(251) to define the secret sharing formula and (2) the authentication code is generated by the robustness function HMAC (hashed-based message authentication code).

Scientists and engineers from a range of countries discuss such aspects as the successes and failures of the wireless community, linear dispersion codes for wireless communications, a lightweight scheme for node scheduling in wireless sensor networks, cognitive radio wireless networks, an agent-based and network-aware approach to grid resource scheduling, and message authentication for wireless networks based on ant-colony optimization.
Initially the Hash Message Authentication Code (HMAC) of the original image is computed using the iterative cryptographic hash function MD5 (Message-Digest algorithm 5).
