  2. LEB128 - Wikipedia

    en.wikipedia.org/wiki/LEB128

    LEB128 or Little Endian Base 128 is a variable-length code compression used to store arbitrarily large integers in a small number of bytes. LEB128 is used in the DWARF debug file format [ 1 ] [ 2 ] and the WebAssembly binary encoding for all integer literals.

  4. Endianness - Wikipedia

    en.wikipedia.org/wiki/Endianness

    For instance, the 32-bit desktop-oriented PowerPC processors in little-endian mode act as little-endian from the point of view of the executing programs, but they require the motherboard to perform a 64-bit swap across all 8 byte lanes to ensure that the little-endian view of things will apply to I/O devices. In the absence of this unusual ...

  5. AES-GCM-SIV - Wikipedia

    en.wikipedia.org/wiki/AES-GCM-SIV

    Like Galois/Counter Mode, AES-GCM-SIV combines the well-known counter mode of encryption with the Galois mode of authentication. The key feature is the use of a synthetic initialization vector (SIV) which is computed with Galois field multiplication using a construction called POLYVAL (a little-endian variant of Galois/Counter Mode's GHASH).

  6. Fletcher's checksum - Wikipedia

    en.wikipedia.org/wiki/Fletcher's_checksum

    An ordering problem that is easy to envision occurs when the data word is transferred byte-by-byte between a big-endian system and a little-endian system and the Fletcher-32 checksum is computed. If blocks are extracted from the data word in memory by a simple read of a 16-bit unsigned integer, then the values of the blocks will be different in ...

    The round constant rcon i for round i of the key expansion is the 32-bit word: [note 2] = [] where rc i is an eight-bit value defined as : = {= > < > where is the bitwise XOR operator and constants such as 00 16 and 11B 16 are given in hexadecimal.
