- 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.
What Does Mac Stand For Apple
Freddie Mac is a government-owned corporation that buys mortgages and packages them into mortgage-backed securities. Its official title is the Federal Home Loan Mortgage Corporation or FHLMC. Banks use the funds received from Freddie to make new loans to homebuyers. That boosts the housing market and allows more Americans to become homeowners. Jan 08, 2008 it doesnt the three people who started MAC makeup, their first names began with the letters MAC, so i guess it down stand for something, but not like a word or anything.

What Does Mac Stand For In Mac Address
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. https://vividtree493.weebly.com/blog/xvid-codec-for-mac.
