Abstract

The invention provides a safe connection establishing method, a safe connection establishing system, a client, and a server. The safe connection establishing method comprises steps that a negotiationrequest is transmitted to the server, and response information returned by the server based on the negotiation request is acquired, and comprises related information of commercial cipher code encryption suite used for safe connection verification; a to-be-signed abstract is determined based on the negotiation request and the response information, and is transmitted to USB key equipment, and thenthe USB key equipment is used to sign the to-be-signed abstract by the commercial cipher code encryption suite to acquire signature information; the signature information transmitted by the USB key equipment is acquired, and is transmitted to the server for the verification of the safe connection, and when the verification is passed, the commercial cipher code safe connection between the client and the server is established. According to the invention, a technical problem of low data safety performance of conventional safe connection ways used for establishing the safe connection for the dataexchange is solved.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to a method and system for establishing a secure connection, as well as a client and a server. Background technique [0002] With the rapid development of the Internet, both parties communicating with each other can easily obtain each other's information. This increases the risk of some sensitive or valuable data being misused, especially in the field of e-commerce. In order to ensure the security of the two parties communicating with each other and prevent fraud during the communication process, a trust mechanism must be established on the Internet. This requires that both parties communicating with each other must have legal identities and be able to be verified effectively and without error on the Internet. [0003] Using digital certificates to establish a secure connection can make network transmission more secure. One way of establishing a secure connec...
