METHOD FOR DISTRIBUTING KEYS IN LARGE SYSTEM DISTRIBUTED OVER SIGNIFICANT SPACE

摘要

FIELD: secret communications engineering, possible use for transferring, detecting and changing cryptographic keys for users in spatially distributed system.;SUBSTANCE: for realization of method to key distribution center biometric images of user are delivered once and recorded, source artificial neural network is generated and user key as well, aforementioned neural network is taught so, that during its input to biometric image of user it spawned user key at outputs, after that neural network taught in such a way is delivered to user object via open communication channels, where it is recorded and utilized for forming key by feeding to its input by user of his biometric image, and if it is necessary to change the key new key is generated in center, source artificial neural network is taught again on new key and transformed neural network is delivered along open communication channel to user object, where it is recorded and utilized for receiving new key.;EFFECT: possible transmission to user of cryptographic keys, transformed using biometric parameters of this user to neural network, via open communication channel.;2 cl
