Abstract

The invention discloses a client authentication method, and the method comprises the steps: a client sends an identity authentication request to an authentication center, the authentication center determines a target server after the authentication is passed, and generates voucher content at least according to the server address of the target server and preset failure time, performs digital signature on the certificate content by adopting a public private key to obtain a certificate signature, and returns the certificate content and the certificate signature as an authentication certificate; the client sends the authentication credential to the target server according to the server address; the target server performs signature verification on the authentication credential by adopting the public key, verifies whether the authentication credential is valid or not according to preset failure time, and returns a verification success message to the client when determining that the signature verification is correct and the authentication credential is valid; and after receiving the verification success message, the client performs service data interaction with the target server. According to the client authentication method, the problem of server key leakage is effectively avoided.

Description

technical field [0001] The invention relates to the field of security technology, in particular to a client authentication method. Background technique [0002] Currently, the client and the server providing the remote desktop service exchange remote desktop service data through the RFB remote control protocol. RFB supports the vnc password authentication mode. The client sends the password (server key) entered by the user as a key encrypted random string to the server, and the server verifies the random string through the local key to realize user authorization authentication. Since Remote Desktop Services is deployed on batch-generated remote desktop servers, each user needs to exchange keys with each server, which greatly increases the risk of server key disclosure. Contents of the invention [0003] The main purpose of the present invention is to provide a client authentication method, aiming to solve the technical problem of high risk of server key leakage in the exi...
