Stands for 'Media Access Control Address,' and no, it is not related Apple Macintosh computers. A MAC address is a hardware identification number that uniquely identifies each device on a network. Grammarly for mac mail. The MAC address is manufactured into every network card, such as an Ethernet card or Wi-Fi card, and therefore cannot be changed.
Because there are millions of networkable devices in existence, and each device needs to have a unique MAC address, there must be a very wide range of possible addresses. For this reason, MAC addresses are made up of six two-digit hexadecimal numbers, separated by colons. For example, an Ethernet card may have a MAC address of 00:0d:83:b1:c0:8e. Fortunately, you do not need to know this address, since it is automatically recognized by most networks.
- CMAC
- In cryptography, CMAC is a block cipher-based message authentication code algorithm. It may be used to provide assurance of the authenticity and, hence, the integrity of binary data. This mode of operation fixes security deficiencies of CBC-MAC.The core of the CMAC algorithm is a variation of CBC-MAC that Black and Rogaway proposed and analyzed under the name XCBC and submitted to NIST. The XCBC algorithm efficiently addresses the security deficiencies of CBC-MAC, but requires three keys. Iwata and Kurosawa proposed an improvement of XCBC and named the resulting algorithm One-Key CBC-MAC in their papers. They later submitted OMAC1, a refinement of OMAC, and additional security analysis. The OMAC algorithm reduces the amount of key material required for XCBC. CMAC is equivalent to OMAC1.To generate an ℓ-bit CMAC tag of a message using a b-bit block cipher and a secret key, one first generates two b-bit sub-keys using the following algorithm. Let ≪ signify a standard left-shift operator:Calculate a temporary value k₀ = Eₖ.

Which means that MAC is an acronym for Makeup Art Cosmetics. So mindblowing, in fact, that we’ve stuck that information in a fact box for you, so you can stare at it in wonder. Apr 04, 2017 What does iOS Stand for? Apple first introduced the now iconic ‘i’ branding with the iMac in 1998. During the announcement Steve Jobs shared that the primary meaning “comes from the. A Media Access Control address (MAC address) is a unique identifier assigned to network interfaces for communications on the physical network segment. Logically, MAC addresses are used in the Media Access Control protocol sub-layer of the OSI reference model. Monitored Anesthesia Care (MAC), also known as conscious sedation or twilight sleep, is a type of sedation that is administered through an IV to make a patient sleepy and calm during a procedure. The patient is typically awake, but groggy, and are able to follow instructions as needed.
