摘要

In this paper is presented a protection method for Eurocom D1 circuits. A study of continuous variable slope delta (CVSD) codecs was performed. Method consists in an operation of permutation executing on digital signal obtaining from CVSD Codec on emission. Permutation function is chosen from a set of permutation based on index number provided by a chaotically generator. The number of permutation set function is depending of number of bits inside of permutation block. Chaotically generators are periodically synchronized using impulsive synchronization. These impulses have been transmitted periodically using separate channel. A statistical analysis was performed in conditions of an AWGN Channel. According to all of these is proposing a set of measures in order to protect the information from source to destination.
