FIELD: physics, computer engineering. ^ SUBSTANCE: invention refers to local networks. Substance of the invention consists that network includes at least one reproducer of encrypted data flow, and device designed for transmission and reencryption of all specified encrypted data or a part thereof. These devices are equipped with security modules. Method includes following steps: connection of the principal security module to one device within local network: following network key generation by the principal security module; protected network key transfer to one or several so-called security subscriber modules; decryption of data encrypted with device of transmission and reencryption; data reencryption with local key by the specified device; transmission of reencrypted data to reproducer; maintenance of decryption by reproducer through security subscriber module with connected local key detector. ^ EFFECT: higher data communications security. ^ 13 cl, 1 dwg |
