Problems solved by technology

For the complex and dynamic environment of the Internet, huge authentication policies and restrictive measures have been set up. Currently, the most widely used SSL / TLS supports dozens of cipher suites, complex processing logic, and a large and redundant code system. Undoubtedly increases the data processing burden of the automotive electronic control unit (Electronic Control Unit, ECU)

Abstract

The invention discloses a communication method, device, system, equipment and storage medium. The method includes: encrypting a first preset random number set with a randomly generated first AES key to obtain a first communication ciphertext; sending the first communication ciphertext to a server so that the server uses a randomly generated second AES cipher key to decrypt the first communication ciphertext; receive the second communication ciphertext returned by the server, the second communication ciphertext is obtained by encrypting the second preset random number set with the second AES key; decrypt the second communication ciphertext with the first AES key Two communication ciphertexts to obtain a first decrypted message; if the first decrypted message contains the same random number field as the second preset random number set, encrypted communication is performed. The embodiment of the present invention realizes the encryption of optional data of the server and the client while reducing code redundancy, thereby ensuring the confidentiality, integrity and authenticity of communication and data.

Description

Technical field [0001] Embodiments of the present invention relate to communication technologies, and more particularly to a communication method, apparatus, system, device, and storage medium. Background technique [0002] With the increasing importance of automotive electronics, in order to meet the increasing function of electronic vehicles, automotive Ethernet and automobile Wi-Fi communications are gradually popular in car communications, and how to guarantee in more and more open car communications Communication security of car Ethernet and car Wi-Fi is critical. [0003] Traditional cars are a closed environment that does not require additional safety measures. Also, traditional Ethernet communication and Wi-Fi communication are based on Secure Sockets Layer, SSLs / Transport Layer Security (TLS), Internet Protocol Security, IPSec, virtual dedicated Virtual Private Network, VPN, etc. For the complex dynamic environment of the Internet, large certification strategies and re...
