Embodiment Construction

[0052] figure 1 It is a block diagram of a system for encrypting and authenticating online bank data using an IC card according to the present invention. Such as figure 1 As shown, the notarial certificate user 102 refers to the public online banking user who owns the IC card 101 storing the certificate. For the notarial certificate, the user 102 can access the Internet network 103 to connect to the online banking system through the client browser, conduct online banking transactions or download digital certificates.

[0053]The NetSafe server (using Principal's NetSafe product) 104 provides user identity authentication service, receives the client's HTTPS request and forwards it to the Web server 105. Web server (using Microsoft's IIS product) 105 implements a function in the existing online banking system to receive the user's Http request and forward the request to the online banking system application server 107 through the IIS plug-in program (WebSphere plug-in). The a...

Abstract

The method includes steps: based on user's information, generating digital certificate aimed at the user; storing the said digital certificate onto IC card to be distributed to the user; when the user logs on network bank to carry out data process for the user, authenticating user's ID or digital signature through the said IC card. The invention also discloses a system for realizing the said method. Since each IC card possesses a unique card number, and private key cannot be output from memory, network business can be carried out only after the user's ID is authenticated. Thus, the invention has high privacy and security.

Description

technical field [0001] The invention relates to an information encryption technology, in particular to a method and a system for authenticating online bank data by using an IC card. Background technique [0002] With the vigorous development of online banking business, data security and user identity authentication have become more and more important issues. For data security transmission, the existing technology mainly uses the SSL (Secure Socket Layer) protocol, and the encryption strength has basically reached a "satisfactory" level, but there are various ways to confirm the identity of the "networker". method. For online banking, identity authentication is particularly important. Only by confirming the legal identity of bank users can we provide users with safe, high-quality, efficient services and more and more comprehensive service functions. Otherwise, it is impossible to guarantee the safety of the funds of users and the bank itself, and it is impossible to talk a...
