Software and hardware protection of control channels in unsecure medium

The principals of devices creation for arrangement of secure channels in unsecure communication environment have been analyzed. To use encryption algorithm AES enhanced with a system of dynamic encryption key generation as a solution of protection problem is offered. The system of encryption key generation offered by the authors is based upon combinatory properties of Latin matrix. Test computer simulation of the offered encryption algorithm performance was run. Using the algorithm working models of protection devices for system of mobile object remote control by radio link were built.
