Safety communication method, device and system and safety mainboard

Abstract

The invention provides a safety communication method. The method includes: a first drive layer of a transmitting end performs protocol type checking on data packets to be transmitted, determines protocol type of the data packets to be transmitted, and encrypts front one or multiple fields of the data packets and / or data components of the data packets according to the protocol type; the transmitting end transmits the encrypted data packets to a receiving end; a first drive layer of the receiving end performs protocol type checking on the data packets received, determines the protocol type of the data packets received, decrypts the front one or multiple fields of the data packets and / or the data components of the data packets according to the protocol type in response to the transmitting end, and discards the data packets if decrypting fails; a second drive layer of the receiving end verifies the data packets successfully decrypted and discards the data packets if verifying fails. The safety communication method has the advantages that network communication agent confirmation is achieved and network-transmitted information can be protected from breach.

Description

technical field [0001] The invention relates to the field of computer network security, in particular to a secure communication method, device, system and secure main board. Background technique [0002] Network security protection is a kind of network security technology, which refers to technical solutions such as how to effectively carry out intervention control and how to ensure the security of data transmission, mainly including physical security analysis technology, network structure security analysis technology, system security analysis technology , manage security analysis techniques, and other security services and security mechanism strategies. [0003] Existing mechanisms cannot prevent malicious programs from intercepting network data packets during network communication (wired communication or wireless communication), and masquerading as a communication subject to communicate with a target subject. For example, under Windows, for TCP and UDP protocol communicat...

Problems solved by technology

[0003] The existing mechanism cannot prevent malicious programs from intercepting network data packets during network communication (wired communication or wireless communication), and pretending to be the communication subject to communicate with the target subject

For example, under Windows, for TCP and UDP protocol communication, malicious programs can forward data packets in disguise by hooking up to SPI (Service Provider Interface), resulting in information leakage
