Description: Methods of modifying linear block codes (elliptic codes) for constructing crypto-code designs are considered. The modification method is shortened in detail. The mathematical model of the modified asymmetric crypto-code system (MACCS) of the Nethereright on elliptic codes is considered. Applied algorithms for the formation and decryption of cryptograms in MACCS on the basis of modified crypto-code designs are offered. A block diagram of algorithms for the formation and decryption of cryptograms in the ACCS Niderraiter based on modified crypto-code designs, taking into account the peculiarities of implementation, has been developed. The research of the properties of the modified ACCS Niderraiter was carried out: the dependence of the complexity of the formation of cryptograms, the complexity of decrypting the cryptogram, the complexity of the burglary and the complexity of coding have been investigated. According to the results of the research, despite the reduction of field strength for the MACCS, the characteristics of such crypto-code designs were, at least, not worse than the traditional ACCS Niderraiter. In this way, the MACCS of Niderraiter is a competitive system for providing basic security services and is a promising direction of research on reducing energy consumption of cryptographic transformations in CCS using code structures, by modifying them.
