Description
Technical field
What the present invention relates to is the system in a kind of mobile communication technology field, and particularly a kind of smart card dynamic password generates and the judgement system.
Background technology
In computer network, the most common and the simplest access control method is to use password, by the coupling of password being confirmed user's legitimacy.Password is dangerous to be ubiquitous hidden danger in the network system.Nearly thousand network managers' of company investigation is shown have 60% system at first to be attacked and the position broken through is a password according to the professional safe association of the U.S., and loaded down with trivial details password setting brings a lot of troubles to the user, and this system manager is felt in a dilemma.
Along with popularizing of computer and network system, increasing user uses user name and the account password means as authenticating identity, for example e-mail system, electronic transaction, online payment, Web bank, online game etc. on electronic system.Yet use the fixing user name and the method for account password, potential hazards such as its risk highlights day by day, and wooden horse is stolen, network interception, exhaustive attack and user use single password for a long time make the authentication of electronic system, the legitimacy of user's login be subjected to serious challenge.
Based on above-mentioned background, people have proposed disposable dynamic password technology, its principle is: the user grasps specific hardware device and moves software on it, before needs carry out system login, calculate the required disposable dynamic password of this login by this firmware by the certain algorithm and the factor, and by man-machine interface this password being informed the user by this firmware, the user uses the dynamic password that obtains to substitute or login as the electronic system side that replenishes of fixed password.The dynamic password technology is widely used in bank, security, government, the tax and the enterprise-essential system, has proved the effective value of its raising system and user security in application.
Find by prior art documents: in the mobile communication technology field with the closely-related system of dynamic password technology, as: Chinese utility application number be: 200620124699 (publication number is CN2938239), name is called: a kind of dynamic password provides system and dynamic password that equipment is provided.This technology readme: dynamic password provides and comprises interface and dynamic password output unit, electronic signature functionality unit and dynamic password generation unit in the equipment, comprises interface unit and electronic signature applying unit in the computer.Interface unit will connect signal and be sent to the electronic signature applying unit, the electronic signature applying unit is after receiving the connection signal, by interface unit, interface and dynamic password output unit and electronic signature functionality unit, dynamic password is generated indication be sent to the dynamic password generation unit; The dynamic password generation unit is used for generating dynamic password after receiving dynamic password generation indication, the dynamic password that is generated is sent to interface and dynamic password output unit, interface and dynamic password output unit output dynamic password.And for example: the Chinese invention patent application number is: 200610169595 (publication number is CN1987938), name is called: a kind of dynamic password provides system and dynamic password that equipment is provided.This technology readme: a kind of dynamic cipher method, system and dynamic password card are provided, and described dynamic cipher method comprises: generation-group dynamic password at random, and each dynamic password all has uniqueness; Described dynamic password is stored, and set up the corresponding relation of each dynamic password and a coordinate data; When carrying out the dynamic password safety certification: the prompting coordinate data; Input and the corresponding dynamic password of coordinate data of pointing out; Whether the coordinate data pairing dynamic password identical with described prompting coordinate data of judging storage be identical with the dynamic password of input, if then Shu Ru dynamic password through safety certification.
But above-mentioned two Technology Needs obtain dynamic password by specific special equipment and aid, all exist and carry and use inconvenient defective.
In further to the dynamic password technical Analysis in the mobile communication technology field, think: Chinese utility application number is: CN200420036971 (publication number is CN2746689), name is called: the module that produces dynamic password in a kind of mobile phone or the mobile device.This technology readme: relate to the module that produces dynamic password in a kind of mobile phone or the mobile device.By implant procedure code in the memory module of mobile communication equipments such as mobile phone, PDA, form the dynamic password module in mobile phone or the mobile device, thereby do not need the specific password generator, produce high security network security dynamic password.
There is the problem of program platform poor compatibility in this technology for the practical application on the different external equipments, for different types, the external equipment of model, still need the professional and technical personnel to develop and provide special project targetedly technology implant the dynamic password generator respectively, and this technology does not have the detailed process that how dynamic password to generate and the description of application in telecom intelligent card, how to face identical compatibility and open application difficult in server-side certificate after generating for dynamic password yet.
