In cryptography, a cipher block chaining message authentication code (CBC-MAC) is a technique for constructing a message authentication code (MAC) from a block cipher.The message is encrypted with some block cipher algorithm in cipher block chaining (CBC) mode to create a chain of blocks such that each block depends on the proper encryption of the previous block.
Code::Blocks is a free, open-source, cross-platform IDE that supports multiple compilers including GCC, Clang and Visual C++. It is developed in C++ using wxWidgets as the GUI toolkit. Using a plugin architecture, its capabilities and features are defined by the provided plugins.
The M1 is a system on a chip fabricated by TSMC on the 5 nm process and contains 16 billion transistors. Its CPU cores are the first to be used in a Mac processor designed by Apple and the first to use the ARM instruction set architecture. It has 8 CPU cores (4 performance and 4 efficiency), up to 8 GPU cores, and a 16-core Neural Engine, as ...
Apple M1 is a series of ARM-based system-on-a-chip (SoC) designed by Apple Inc., part of the Apple silicon series, as a central processing unit (CPU) and graphics processing unit (GPU) for its Mac desktops and notebooks, and the iPad Pro and iPad Air tablets.
One-key MAC (OMAC) is a family of message authentication codes constructed from a block cipher much like the CBC-MAC algorithm. It may be used to provide assurance of the authenticity and, hence, the integrity of data. Two versions are defined: The original OMAC of February 2003, which is seldom used. The preferred name is now "OMAC2".
The internal codenames of Mac OS X 10.0 through 10.2 are big cats. In Mac OS X 10.2, the internal codename "Jaguar" was used as a public name, and, for subsequent Mac OS X releases, big cat names were used as public names through until OS X 10.8 "Mountain Lion", and wine names were used as internal codenames through until OS X 10.10 "Syrah".
A mode of operation describes how to repeatedly apply a cipher's single-block operation to securely transform amounts of data larger than a block. [3] [4] [5] Most modes require a unique binary sequence, often called an initialization vector (IV), for each encryption operation. The IV must be non-repeating, and for some modes must also be random.
apple .com /macbook-air. The MacBook Air is a line of Mac laptops made by Apple Inc. In 2020, Apple stopped using Intel processors in the Air and switched to using their own Apple silicon M-series chips. In the current product line, the MacBook Air is Apple's entry-level laptop, situated below the performance range MacBook Pro, and is currently ...
