Abstract

One of the main tasks of the critical infrastructure process control system is information protection. Information security is important for the transport system, including the railway one. The paper proposes a graph approach to the construction of absolutely failure-free data transmission systems by creating ciphers that do not disclose any information about encrypted texts. A class of minimal perfectly secure Shannon ciphers is considered, in which for each pair of ciphertexts and ciphervalues, ),( yx respectively, there are at most two keys on which x is encrypted into y . For ciphers of this class, a graph is defined on a set of keys, namely: two different keys are connected by an edge if there is such a pair ),( yx that on both of these keys the ciphertext x is encrypted into a ciphervalue y . Within the framework of this approach, the necessary and sufficient minimality condition for the inclusion of perfect ciphers is proved. The minimality criterion for the inclusion of perfect ciphers is formulated. Examples illustrating the concepts used and the theoretical statements obtained are constructed. The tables of encryption of perfect ciphers are given, which ensure data protection when they are transmitted over a communication channel on transport.
