Abstract
Protection of information in the modern world it is an important and relevant challenge, especially when it comes to data transmission channels. Currently, you can find a lot of means of protection of data transmission channels, software and hardware - software. Software means of protection less efficient with respect to the hardware – software. Software - hardware is much more expensive, and almost all of them are of foreign manufacture. The paper solves a number of problems of secure data transmission on the optical channel through the development of high-speed reconfigurable codec (encoder / decoder) based on the encryption standard AES-128. Developed the device that is using the optical SFP module is attached to a computer network adapter for transmitting and receiving, thereby forming a secure connection. The device able to receive information from network card and pass on without additional driver. This makes it completely universal. In addition to a universal architecture, the creation of high-speed reconfigurable codec involves the creation of a kind of logical scheme, which includes the area of reconfigurable encryption algorithm. This will allow mode of the device, depending on the task, to change the encryption algorithm. The effectiveness of this approach lies in the possibility using multiple encryption algorithms. Testing of the codec the boards Xilinx. The results of the study. Invented device ultimately is compact, thus combining the unique architecture and unified interface.
Keywords: protection of information, software - hardware, partial reconfiguration FPGA, en-coder / decoder, encryption tool, encryption in the optical data transmission channel, protected data transmission channel, optical channel
