Abstract

The invention discloses a safe computer network communication system. The system comprises a sending end sandbox isolation system, a file transmission unit and a receiving end; the sending end sandboxisolation system comprises an analog signal copy output module, an analog signal storage module, a file compression system, a security encryption system, a key file conversion unit, a file decryptionprogram, a signal key binding module and a firewall protection system. The invention relates to the technical field of communication systems. The invention discloses the safe computer network communication system. A secret key is divided into two parts according to a specified coding sequence, wherein the two parts are bound to a transmitted compressed packet and a transmitted file decryption program respectively and are transmitted twice, wherein the secret keys in one time are incomplete, and files cannot be cracked even if one group is stolen, so the safety of data is further guaranteed, and the method is suitable for transmission of confidential files; meanwhile, a file decryption program is attached to the method, after all the data are completely received, the decryption and decompression can be rapidly and automatically conducted, and manual step-by-step operation is not needed.

Description

technical field [0001] The invention relates to the technical field of communication systems, in particular to a secure computer network communication system. Background technique [0002] Communication system is a general term for technical systems used to complete the process of information transmission. Modern communication systems are mainly realized by the propagation of electromagnetic waves in free space or the transmission mechanism in guiding media. The former is called a wireless communication system, and the latter is called a wired communication system. A system that uses electrical signals (or optical signals) to transmit information, also known as telecommunication systems. A system is usually an organic whole composed of a number of units with specific functions, interactions and interdependencies to accomplish a unified goal. The simplest communication system for users at two points to send and receive information from each other. In a general communicatio...
