A SECURE DOCUMENT MANAGEMENT DEVICE BASED ON REALTIME PACKET ANALYSIS FOR MONITORING TRANSFER TO PORTABLE STORAGES AND THE METHOD THEREOF

摘要

PURPOSE: the user terminal in document is inserted into a kind of actually providing in certification grouping for the external memory that managing device carries out document based on fractional analysis monitoring document, certification grouping is set to go out External memory equipment to carry unique authentication file, to prevent leakage document. ;CONSTITUTION: cryptographic communication unit (31) distributes session key from server. Document authentication request unit (32) request certification is by transmitting a document into server, when the leakage of request document is stored in the input of user terminal to storage equipment. It authenticates packet authentication unit (33) and receives a file, certification grouping is inserted into the message from server. It authenticates in packet authentication unit verifying packet and extracts certification the author got two thousand yuan in advance as part of his contribution fee document. Document leakage unit (34) executes storage equipment by extracting document from the above-mentioned file through notarizing, when the verifying of certification grouping. ;The 2013 of copyright KIPO submissions;[Reference numerals] (31) cryptographic communication unit; (32) document authentication request unit; (33) packet authentication unit is authenticated; (34) document leakage unit; (35) authentication unit of user; (36) medium control unit
