Embodiment Construction

[0020] The embodiment of the present invention adopts the smart card technology and uses the widely used mobile terminal as the carrier of the smart card to provide a new form of identity authentication. Realize safe and convenient identity authentication by using the mobile phone instead of the dynamic token as the authentication medium. It changes the drawbacks of existing users who must carry additional dynamic tokens and other identity authentication products for identity authentication, and solves the problem of the service life of token products.

[0021] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

Abstract

The invention discloses a system of realizing dynamic identification authentication, comprising an intelligent card, a cell phone, an authentication terminal and an authentication server. The invention further discloses a method for realizing the dynamic identification authentication, including the following steps: the intelligent card pre-stores a seed key and an algorithm; a dynamic password required by the authentication is generated by utilizing the algorithm, the seed key and an appointed authentication factor, and is sent to the cell phone which receives and displays the dynamic password; the user enters the dynamic password and user information into the authentication terminal and uploads the dynamic password and user information to an authentication server; the authentication server obtains the seed key of the user from the authentication server according to the user information and carries out the calculation of the seed key and the appointed authentication factor with the prestored algorithm, thus also generating the dynamic password; and comparison of the dynamic passwords at two terminals is carried out, thereby completing the authentication. The invention overcomes the existing defect that the identification authentication of the user is required, and the user additionally carries a dynamic password card and other identification authentication products, simultaneously, the problem about the service life of the password card is solved.

Description

technical field [0001] The invention relates to authentication technology, in particular to a method and system for realizing dynamic identity authentication. Background technique [0002] With the continuous development of identity authentication technology, the traditional static password authentication method is gradually recognized by people because of its long-term invariance and effectiveness and the danger of easy interception, attack, and guessing, and thus the dynamic password technology appears. Dynamic Password (Dynamic Password), also known as "One Time Password (OTP: One Time Password)", is generally generated by handheld terminal devices such as software tokens or electronic tokens. [0003] Token is a new type of two-factor authentication product. It uses a dynamic password generated by a certain algorithm based on a certain changing factor to ensure the security of authentication. It is easy to use, low in price, and does not need to be installed. Advantages...
