Asynchronous Method of Generating Stream Ciphers in a Group of Robots Based on Cellular Automata with Active Cells

The paper solves the problem of effectively organizing the exchange of information in a group of robots, through the use of stream ciphers formed on the basis of cellular automata with active cells. The cellular automata with active cells allows to build a model of a pseudorandom number generator that can simultaneously generate many pseudorandom bit sequences. This makes it possible to organize the transmission of messages from one robot to all robots in the group and vice versa. Messages are exchanged using different self-synchronized stream ciphers generated by one device. Each cellular automata contains the number of active cells, which at the output generate a key gamma and form a stream cipher for the corresponding robot in the group. The number of active cells can either increase or decrease during the functioning of a group of robots, which corresponds to the addition or removal of robots in the group.
