PROBLEMS OF LOW-RESOURCE ENCRYPTION FOR CONTROLLING UNMANNED COMPLEXES

The article considers the problem of building a low-resource post-quantum control system in swarms of unmanned systems, which are resistant to external interference, taking into account the requirements for technical support of information protection in a time regime close to real. It is shown that the solution to the specified problem of protection of the information resource circulating in the network is proposed to be performed on the basis of stream encryption technologies using cryptographic transformation operations (CET operations). A mathematical description of the CET operation is provided, which is a numbered set of elementary functions, each of which forms the corresponding output Ci-quantum of information based on the processing of input Ci-quantums of information. The classification of the CET operation is carried out by the number of operands and by the number of Ci-quantums of encoded information. Encryption consists in the sequential bitwise addition modulo two of information and a pseudo-random sequence.The main requirement for the possibility of using any operation in a crypto algorithm is the presence of an inverse transformation operation. The use of CET operations allows to significantly increase the number of cryptographic transformations on the basis of which crypto algorithms are built. The use of low-resource encryption allows to take into account the tactical, operational, economic and ergonomic characteristics of control systems of unmanned complexes. Variants of converting two bits of information are considered. SET operations are built on the basis of combining discrete representations of columns of the original data of the truth tables of operations. The problem of creating low-resource cryptographic systems for protecting information in swarms of BPC is considered. The results of the synthesis of symmetric SET operations and crypto algorithms based on them are studied for compliance with the requirements for protected information systems.
