METHOD FOR CRYPTO KEY EXCHANGE BETWEEN USER'S AND NETWORK COMPUTER UNITS

摘要

protection of data- processing systems against probable interception. SUBSTANCE: first and second intermediate keys are formed in network and user's computer units depending on random numbers generated. Session key is computed by logical integration of first and second intermediate keys. Keys are not transmitted by plaintext. EFFECT: enhanced safety of exchange between computer units due to reduced length of messages transmitted. 9 cl, 4 dwg
