Technical field
The utility model relates to a kind of intelligent finance IC-card.
Background technology
From in Dec, 2005, since industrial and commercial bank releases domestic leader's financial IC card, financial IC card is rapidly grown up under the dual power-assisted of government and market.Central Bank announces on July 19th, 2012, and on January 1st, 2013 rises, and national commercial bank all will issue financial IC card.By the first half of the year in 2012, the accumulative distribution financial IC card more than 4,500 ten thousand in the whole nation, comparatively increase by 2,070 ten thousand the end of the year 2011, amplification reached 85%, realizes financial IC card in increment hair fastener accounting more than 15% before the end of the year.In March, 2011, Central Bank starts bank's magnetic stripe card to IC-card migration work comprehensively.According to the timetable of Central Bank, work, agriculture, in, build, hand over and promote trade and investment, the state-owned large row such as Postal Savings bank gets off the ground financial IC card.Social security card merges with financial IC card, estimates that " 12 " period is by distribution 800,000,000 financial IC cards.
The profile of financial IC card is similar to magnetic stripe card, and different places is the medium that data store.Magnetic stripe card stores information by the changes of magnetic field of magnetic stripe on card, and financial IC card is then carry out storing data information by the integrated circuit (IC) chip embedded in card.Compared with traditional magnetic stripe card, financial IC card has more obvious advantage:
1, the revolutionary advantage of one card for multiple uses is possessed.The memory capacity of financial IC card is hundreds of times of conventional magnetic stripe card, implantable more application program, such as social security, public transport, retail, hospital, self-service ticket and sell goods.Thus financial IC card is widely used each area of collaboration except bank, really realize " one card for multiple uses, all-purpose card are capable ".
2, level security is good.Compare magnetic stripe card, financial IC card possesses very strong anti-attack ability, is difficult to be replicated and forgery.
3, " dodge and pay " quick consumption.Be different from traditional magnetic stripe card and can only have an account, electronic cash account (i.e. " stored value card ") in IC card chip, can also be increased, the account remaining sum upper limit 1000 yuan, realize off line by " dodge and pay " and consume fast.
As computer can suffer attack, CPU card is as the same.In February, 2010, the researchist of Cambridge University finds a considerable safety leak of EMV standard, assailant can utilize this leak to initiate man-in-the-middle attack, communication information between terminal and IC-card is tackled and distorted, cause input any PIN(PIN (Personal Identification Number), the i.e. daily said personal identification number of people) this IC-card can be used.Specifically, assailant is by " go-between " of use electronic equipment as payment terminal and card sending mechanism background system, stop background system PIN being sent to card sending mechanism, and the response of " PIN verification correct " is sent to terminal, so just make non-holder put through deal when not knowing the true off line PIN of card.
Britain carries out bank card chip migration country the earliest, is also implement one of the fastest country.Britain, promoting early stage (before 2005) of this work, uses static data certification (SDA) means to carry out off line certification in offline transaction always.Although the degree of safety of SDA exceeds a lot than magnetic stripe, criminal's molecule is still easy to obtain account data and bank's digital signature to make pseudo-the card, and the risk of off-line trading is still very high.Along with contactless payment application and the offline transaction such as small amount payment application increasing, the domestic pseudo-card fraud loss of Britain is not well contained.Within 2004, the domestic pseudo-card fraud loss amount of money of Britain is still up to 1.06 hundred million pounds, has hit the enthusiasm that financial IC card work is carried out by Britain.
The safety of existing ordinary financial IC-card is from bottom to top, and from the chip hardware safety of bottom, to the chip operating system safety in middle layer, until the application safety of the superiors, its large area is inactive area.
Current financial IC card, has had very large security improvement relative to traditional magnetic stripe card, but still there is certain problem, and the shortcoming of existence is as follows:
1, because current IC-card is a completely passive device, therefore when there is no externally fed, any attack cannot be tackled.
2, when needs are discarded, even if the mode by cutting card, also cannot ensure that the interior data of card are effectively eliminated, as long as the storage area of safety chip inside is not destroyed, information just still exists.
3, after being attacked, particularly under off line certification mode (such as Countries and area is cross-border use time) attack occur after, be difficult to review assailant.
