Description
The technical field is as follows:
the utility model relates to a safety certification device of online bank remote payment based on many interfaces safety smart card.
Background art:
since its birth, bank cards have always existed and developed in the form of magnetic stripe cards. While the magnetic stripe card brings convenience to people, the magnetic stripe card is very easy to copy, and brings high fund risk to the bank card set woven belt. In order to prevent the fraud risk of the magnetic stripe card, the bank card organization introduced the strategy of migrating the bank card from the magnetic stripe card to the smart chip card (i.e. EMV migration). Migration has been implemented in many countries and regions. At present, China also enters a transition stage of upgrading a magnetic stripe card to an intelligent chip bank card, and both domestic technical conditions and card using environments are provided. In the upgrading process, the mode that the intelligent chip bank card directly adopts the multi-interface (namely a contact interface, a non-contact interface and a human-computer interaction interface) secure intelligent card is undoubtedly a one-step selection. The system can realize various transactions including PBOC2.0 and EMV through a contact interface, and ensure the safety; the functions of safe micropayment transaction and the like can be realized through a non-contact interface; but also can display key transaction information to the user by using a man-machine interaction interface of the smart card and can wait for the key pressing confirmation of the user. Therefore, the user can easily realize one card for multiple purposes.
The Internet bank is also called on-line bank and Internet bank, which means that the bank provides traditional service items such as opening an account, selling an account, inquiring, reconciling, in-line transfer, cross-line transfer, credit, online stock certificates, investment and financing and the like to a customer through the Internet by using the Internet technology, so that the customer can safely and conveniently manage the current and regular deposit, checks, credit cards, personal investment and the like without going out.
Since online transactions are not face-to-face, users can make requests at any time and any place, and the traditional identification method usually authenticates the identity of the user by a user name and a login password. However, if the password of the user is transmitted over the network in a plaintext manner during login, the password is easily intercepted by an attacker, and further the identity of the user can be counterfeited, so that the identity authentication mechanism can be broken.
At present, the online bank personal authentication media (security tools) mainly include: passwords, file digital certificates, dynamic password cards, dynamic cell phone passwords, mobile password tokens, mobile digital certificates, and the like. The mobile digital certificate is actually a kind of usb key. Different banks in China are called differently, such as the Ministry of industry called U shield and the Ministry of agriculture called K Bao. The USBKey stores personal digital certificates of users. The personal identity authentication through the USBKey is the relatively most safe mode in the existing online bank personal authentication method.
One of the problems of using the USBKey authentication method is that in addition to the requirement of applying for a bank card before the banking business is launched, the user needs to be additionally provided with a corresponding USBKey. With the increasing popularity of online banking, users who select the usb key to protect the security of the online banking have reached a considerable number. If the bank card of the multi-interface security smart card is used, the multi-interface security smart bank card can be directly used to replace the USBKey. Therefore, the method can save a considerable cost for distributing the USBKey and has good social and economic benefits. Meanwhile, when the user uses the internet bank, the user can use the internet bank more conveniently because only the multi-interface security smart card (appearing in a bank card mode) is needed to be owned and the USBKey is not needed to be additionally used.
In addition, the USBKey is not absolutely safe, and the USBKey which is widely applied at present actually has two security vulnerabilities: 1) there is a vulnerability to the interactive operation. An attacker can carry out remote control, and impersonates the USBKey of the user to carry out identity authentication, but the user cannot know the USBKey. 2) Data cannot be prevented from being tampered. Before the user sends the USB Key to encrypt, the user may be tampered with another transaction by an attacker intercepting screen, so that the user can tamper with the transaction without knowing the user and the authentication is passed. The above two security problems can be solved by combining the human-computer interaction interface in the multi-interface security smart card. The key information of each transaction is displayed on a display interface in the human-computer interaction interface of the multi-interface security intelligent card, and the transaction can be normally and successfully carried out only after a user presses a confirmation key on the human-computer interaction interface of the multi-interface security intelligent card, so that the safety and reliability of the transaction are ensured.
