With the One-time password, authentication system developed by HierStar can effectively prevent account theft and Trojan attack. With E-signature, system can protect users’s transactions; prevent man-in-the-middle attacks. With challenge/response two-factor authentication, system can secure online transfers and online transactions.

System provides authentication function based on one-time password. System receive users’ information ( such as account number, one-time password, etc) from application interface or application system (such as RADIUS application); then, read correspondence information from data base and conduct authentication; finally, system send back the results to authentication proxyor or application system, and record users’ authentication information.

System includes standard RADIUS authentication server and extended RADIUS authentication server. System deployment should be based on corresponding authentication service.

With authentication proxy, users can only need a simply configuration without second development, which can integrate dynamic authentication service. System SDK provides authentication function to users in the form of interface. These interfaces can be integrated to users’ application system to achieve seamless integration.
