Abstract
The invention discloses a password authentication system, which comprises a system server and an authentication password generator, wherein the system server comprises a system interface for outputting an additional code and receiving an identity password and the additional code and a system database for storing user identity information; the authentication password generator comprises an identity password register for storing the user identity information, a clock for generating a time digital value, a password generation module, an input module and a display module; the display module is a liquid crystal display module; and the password generation module is a singlechip for calculating by adopting an algorithm compiled based on a sha-1 algorithm. According to the password authentication system, the algorithms can be different in each password generator, so that dynamically variable identity passwords can be randomly generated according to the identity information, and the security of the system is improved.
Description
Technical field
The present invention relates to the network system field, particularly relate to a kind of cipher authentication system.
Background technology
Authentication is an indispensable and vital link that guarantees system safety and stable operation.The user is in the access application system; The identity that needs at first to differentiate the user through Authentication mechanism with declared whether consistent, the authentication success just can determine certain resource that the user whether can access system or carry out a certain operation later on according to user's identity and authorization database.
In the present cipher authentication system since in the authentication process itself password that uses single fixing, be easy to learnt or decode, thereby handling safety caused very big hidden danger by other people.
Summary of the invention
The technical problem that the present invention mainly solves provides a kind of cipher authentication system, can produce identification cipher at random through identity information, has improved the security performance of system.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: a kind of cipher authentication system is provided, comprises: system server and authentication password generator,
Said system server comprises and is used to export extra-code, receives identification cipher and the system interface of extra-code and the system database that is used to store subscriber identity information;
Said authentication password generator comprises the identification cipher register that is used to store subscriber identity information, the clock that is used for the generation time digital value, password generating module, input module and display module.
In preferred embodiment of the present invention, said system server comprises that also one is used for user identity password and the extra-code that the reading system interface is submitted to, and customizes the authentication module of different ciphers production model according to the parameter in the authentication password generator.
In preferred embodiment of the present invention, said display module is a LCD MODULE, and said password generating module is for adopting the single-chip microcomputer of the algorithm computation of writing based on the sha-1 algorithm.
In preferred embodiment of the present invention, said display module is connected with input module with the password generating module.
In preferred embodiment of the present invention; The user obtains a random number through the terminal of system server; With random number input authentication cipher code generator, produce a dynamic password, dynamic password sends the retrieval system server; System server carries out authentication to dynamic password, draws authentication result.
The invention has the beneficial effects as follows: cipher authentication system algorithm of the present invention can be inequality in each cipher code generator, thereby can produce the identification cipher of dynamically changeable through identity information at random, improved the security performance of system.

Embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present invention is set forth in detail, thereby protection scope of the present invention is made more explicit defining so that advantage of the present invention and characteristic can be easier to it will be appreciated by those skilled in the art that.
See also Fig. 1 to Fig. 2, the embodiment of the invention comprises:
A kind of cipher authentication system comprises: system server 1 and authentication password generator 2.
Said system server 1 comprises and is used to export extra-code, receives identification cipher and the system interface 3 of extra-code and the system database 4 that is used to store subscriber identity information.
Said system server 1 comprises that also one is used for user identity password and the extra-code that the reading system interface is submitted to, and customizes the authentication module 5 of different ciphers production model according to the parameter in the authentication password generator.Authentication module 5 adopts the algorithm of writing based on the sha-1 algorithm, differentiates the client identity of the authentication password of input.
Said authentication password generator 2 comprises the identification cipher register 6 that is used to store subscriber identity information, the clock 7 that is used for the generation time digital value, password generating module 8, input module 10 and display module 9.Wherein, display module 9 is connected with input module 10 with password generating module 8.
The time of authentication password and clock can show through display module 9.Display module 9 is a LCD MODULE.Password generating module 8 is for adopting the single-chip microcomputer of the algorithm computation of writing based on the sha-1 algorithm.
Among the present invention, authentication password generator 2 adopts with system server 1 identical algorithm and produces identification cipher, and algorithm can be inequality in each authentication password generator, and identification cipher is a numeric string, and has ageing.
The verification process of cipher authentication system of the present invention is:
The user obtains a random number through the terminal of system server 1, with random number input authentication cipher code generator 2, produces a dynamic password, and dynamic password sends the retrieval system server, and 1 pair of dynamic password of system server carries out authentication, draws authentication result.
The beneficial effect of cipher authentication system of the present invention is:
Algorithm can be inequality in each cipher code generator, thereby can produce the identification cipher of dynamically changeable through identity information at random, improved the security performance of system.
The above is merely embodiments of the invention; Be not so limit claim of the present invention; Every equivalent structure or equivalent flow process conversion that utilizes specification of the present invention and accompanying drawing content to be done; Or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present invention.
