It works by transforming the data using a hash function: an algorithm that consists of bitwise operations, modular additions, and compression functions.

In cryptography, a one-way compression function is a function that transforms two fixed-length inputs into a fixed-length output. The transformation is "one-way", meaning that it is difficult given a particular output to compute inputs which compress to that output. One-way compression functions are not related to conventional data compression algorithms, which instead can be inverted ex… WebCoding theory is the study of codes used to detect and correct errors that emerge before and after data transmission and encryption. Cryptography is a specific coding type, and regards the encryption and decryption of data for the purpose of concealing information from non-authorized entities.

WebCryptography and Compression Engine (LCE) (Hardware Version: 3.0; Firmware Version: B0.4.1 FW 6023) (also referred to as the “module” hereafter). It contains specifications of the security rules, under which the cryptographic module operates, including the security rules derived from the requirements of the FIPS 140-2 standard. 1.2 Overview WebTo ensure correctness of the operation of all cryptographic algorithms, the key compression needs to be lossless. Besides, to protect a resource from unauthorized access by collusion of compromised users, the key compression should not leak information that can ease unauthorized access to any resource key not given to the compromised users.
