High performance encryption tools of visual information based on cellular automata
This article describes a method of encryption of visual information, based on the use of cellular automata. This method allows you to solve problems with noise errors in deciphering information, low-speed, low resistance to cracking, as well as move away from the use of generators of noise signals in the known methods of encryption of visual information. Analyzed modern encryption methods of visual information, as well as problems encountered in their implementation and use in the communication channels. The article also presents the structure of the device that implements - encryption is the visual information based on cellular automata, programs, texts, diagrams and results of the encryption method, the basic characteristics of the used field-programmable gate array. The essence of the method is to encrypt the visual information by overlaying additional transformations besides the usual encryption. The first additional conversion is carried out by the chosen method of encoding and digitizing images. The second transformation is to select the sequence of bit layers and their principles scan each block. Data conversions in the form of numerical values are used as additional fields to the key. In addition, the key is not given as a ready-bit sequence, but as the operation code, the units form a key sequence. Options propagation path of the excitation signal and a three-dimensional map of a cellular automaton states belong to the key sequence. The formation of pseudo-random key range increases reliability and protection to burglary resistance. Due to the three-dimensional image coding, the use of technologies of programmable integrated circuits and cellular automata increases speed encryption. The method allows you to create a key range implicitly, that reduces the probability of selecting an opponent. Encryption tools are implemented on cheap field-programmable gate array with high performance in speed, allowing you to encrypt visual information in real time during its transfer via communication channels.
