Authenticated encryption mode with blocks skipping

Block symmetric ciphers are one of the most important components modern information security systems. At same time, in addition to structure applied block cipher, cryptographic strength and performance protection system is largely determined by encryption mode. In high high-quality destruction statistics, modes should also protect encrypted from occurred or intentionally introduced errors. this paper, we have developed an mode with blocks skipping using a pseudo-random key sequence generator, which allows checking integrity accurate detection place where error was introduced. case, accuracy adjustable parameter macroblock size can be set depending on level importance protected information. The characterized following advantages: reducing number required operations half, while providing quality; more effective statistics due use additional generator sequences, impossibility propagation (intentionally introduced) outside macroblock, as well higher values levels possibility classifying initial states generators sequences. As proposed authenticated recommended for mobile platforms that demanding both terms quality reliability limited computing power resources.
