FIELD: information technologies. ^ SUBSTANCE: at transmitting side prior to conversion into optical signal, spatial switching of channels sending electric signals is carried out, based on change of switching matrix by available law, using random number as an argument, which is generated in time intervals öt, defined by speed of information transfer in channels, while switching matrix changes, synchronising control signals are generated, comprising information on random number used for switching in this time interval, and sent along N+1 channel to receiving side, where after optical-electronic conversion initial signals are restored in channels, by realisation of reverse operation of channels switching according to the same law with application of synchronising control signals for according time intervals. ^ EFFECT: enhanced protection of information. ^ 2 dwg |
