In order to ensure safety of SCCI, it is proposed to use hybrid crypto-code constructions based on the modified asymmetric crypto-code McEliece systems on flawed codes, which make it possible to obtain maximum quantity of emergent properties at minimal resource cost for initiating in the system the synergistic effect of security provision. The main difference from known approaches to the construction of hybrid cryptosystems is the use of MCCS instead of symmetric cryptosystems; to strengthen resistance and to "reduce" the alphabet power (dimensionality of field GF(26–28) to build the McEliece MCCS), the systems on flawed codes are employed.The algorithms proposed in present work for the formation and decryption of a cryptogram in the hybrid cryptosystem based on MCCS on flawed codes make it possible to practically implement HCCSFC. The study that we conducted into energy consumption of major operations in the hybrid cryptosystems and their stability on the basis of the proposed assessment procedure confirms efficiency of their application in order to provide basic requirements to service quality in IES Author Biographies Serhii Yevseiev, Simon Kuznets Kharkiv National University of Economics Nauky ave., 9-А, Kharkiv, Ukraine, 61166 PhD, Associate Professor Department of Information Systems
