Secure access method, system and client

Abstract

The invention provides secure access method, system and client. The secure access method comprises the following steps of: signing and encrypting information inside a secure smart card by using a built-in digital certificate of the secure smart card; sending the information of the signed and encrypted secure smart card to a platform so that the platform can verify the legality of the information of the validity of the digital certificate; after verifying the legality of the information of the validity of the digital certificate, signing and encrypting an access request by using the digital certificate, and sending the signed and encrypted access request to a network-side device to realize secure access. The secure access method, system and client provided by the embodiment of the invention overcome the defect that the legality of hardware KEY can not be guaranteed when network access is realized in the prior art and increase the security of network access.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of network security, and in particular to a secure access method, system and client. Background technique [0002] With the continuous advancement of enterprise informatization, more and more enterprises use the Internet (Internet) to satisfy employees, customers and partners to remotely access enterprise internal network resources, which will inevitably bring certain security threats to the enterprise internal network. , so a secure access mechanism is needed to ensure the security of communications and sensitive information. At present, the main ways for enterprises to achieve secure access through the Internet are Internet Security Virtual Private Network (IP Security Virtual Private Network; IPSec VPN for short) and Security Socket Layer Virtual Private Network (Security SocketLayer Virtual Private Network; SSL VPN for short). ) two kinds. Among them, because the SSLVPN method...
