Algorithm of covert information exchange in information transmission systems with code division multiple access based on chaotic application of orthogonal code sequences

Studenikin A. V.

An algorithm of covert information exchange in information transmission systems with code channel separation based on the chaotic use of multiphase orthogonal code sequences ensembles is presented. The algorithm is implemented on the basis of seven stages and allows to increase the security of information exchange based on structural secrecy. The results of the comparison show that the use of an increased number of ensembles of multiphase orthogonal code sequences represented by the eigenvectors of Hermitian matrices increases the structural secrecy of information transmission systems with code channel separation.
