A data exchange method

Abstract

A data exchange method provided by the present invention includes the steps: a data sending end sends a data exchange request to a server; the server generates a session key according to the above request, and encrypts the session key and sends it to the data sending end ; The data sending end imports the ciphertext of the session key into the USBKEY of the data sending end, and after digitally signing and encrypting the data to be exchanged, designate the data receiving end that receives the data; the data The sending end packages the public key certificate of the data receiving end, the data ciphertext and the digital signature of the data and sends it to the server; the server parses the public key of the data receiving end from the public key certificate of the data receiving end, and uses the public key Encrypting the session key and adding the ciphertext of the session key into the data packet and sending it to the data receiving end; the data receiving end decrypts the data ciphertext in the data packet. This enables efficient enterprise-level data exchange.

Description

technical field [0001] The invention relates to a data exchange method. Background technique [0002] With the continuous development and popularization of modern computer technology and Internet communication technology, the use of the Internet for data exchange has become very common. Since the Internet is an open Internet based on the TCP / IP protocol, when terminals exchange data on the Internet, the data is actually exposed on the network transmission path. At this point, hackers or illegal users use malware to intercept data on the transmission path. [0003] At present, relatively mature data encryption transmission technology (such as the secure socket layer protocol, etc.) can provide strong protection for the data that needs to be transmitted over the network, that is, the two parties that require data exchange need to perform key exchange work, and encrypt and communicate the data. decrypt. Once one party needs to exchange data with multiple parties, that is, on...
