The invention provides a kind of device assisting intelligent memory card to realize safe KEY application, this device includes: USB plug, controller chip, intelligent memory card draw-in groove, display screen, button and radio-frequency antenna.The application present invention is capable of the safe KEY application of intelligent memory card, the range of application of extension intelligent memory card.
Description
Technical field
The present invention relates to intelligent storage card technique, realize safety particularly to one auxiliary intelligent memory card
The device of KEY application.
Background technology
Common memory card only has data storage function, and function is the most single, and intelligent memory card is general except having
Outside the storage function of logical storage card, also have intelligent card function and contactless function of swiping card concurrently, apply model
Enclose very wide, but single by interface, volume is little etc. limits, intelligent memory card function can not obtain well
Application.
Along with maturation and the development of mobile communication technology, the function of mobile intelligent terminal gets more and more.User
Not only require that mobile intelligent terminal has call, the function of transmitting-receiving short message, but also wish that there is peace
Full certification, financial payment, safety call etc. atypia application function.These functions bring
The biggest convenience, meets fast pace, high efficiency social need, is deeply welcome by user.But these should
With mostly requiring that mobile intelligent terminal provides the other service function of higher security level, mobile intelligent terminal is networked
Rear applied environment becomes increasingly complex, and the security threat faced also gets more and more, and existing internet terminal suffers
All kinds of attacks and infringement, mobile intelligent terminal is likely to suffer.But, at present from the point of view of, mobile intelligence
The safety prevention measure relatively fixed network terminal (such as: PC) that energy terminal can be provided by is very limited.Such as,
PC can improve the safety of application by its external equipment U-shield, and mobile intelligent terminal is such as
Mobile phone, owing to not having U-shield interface, it is impossible to improves safety by U-shield.
Existing intelligent memory card only has SD (Secure Digital, safe digital) interface, Zhi Neng
It is furnished with the upper use of terminal (such as mobile phone, digital camera, PDA etc.) of standard SD slot.At present, greatly
Most terminal units such as notebook computer, desktop computer the most do not have SD slot, and intelligent memory card must lead to
Cross interface switching device could use on these terminals.
The intelligent memory card being built-in with radio-frequency module supports contactless communication function, but due to intelligent storage
Card small volume, it is impossible to directly arrange radio-frequency antenna on card body, causes intelligent memory card contactless logical
Telecommunication function is difficult to really realize.
Intelligent memory card has powerful security function, and a typical safety applications is exactly security token
(KEY), being equivalent to now widely used U-shield, intelligent memory card not only may be used unlike U-shield
For PC host terminal, it is also possible to for cell phone type terminal, be equivalent to the USB token of mobile phone version
(USB-KEY), range of application is wider.
Emerge to improve the product of the safety of U-shield, referred to as second-generation U-key further, secondary U
Shield adds " confirmation " and " cancellation " button on product casing, and be used for showing dealing money and
The LCDs of Transaction Account number.
Intelligent memory card is owing to being limited by volume is little, it is impossible to increases display screen the most on its housing and presses
Button, it is impossible to realize the function of second-generation U-key.
