Therefore, perfect unification of rapidness of payment at the credit merchants and security of payment at the common merchants is achieved.
Description
Technical field
The invention belongs to information security field.The present invention relates to be non-contact device pay in common businessman time, use state device to increase safety; And retain the device and method of contactless payment advantage while paying in credit businessman.Specifically, relate to a kind of device and method that carries out respectively contactless payment in no-contact electronic wallet for credit businessman and common businessman.
Background technology
Adopt the no-contact electronic wallet of radio-frequency technique due to its convenience, particularly in " Bus Card ", obtain application widely.Now, a lot of people wish to expand the scope of application of all-purpose card card.For example, using all-purpose card card as common " stored value card " for other small amount payments such as doing shopping." POS " machine of radio-frequency card card reader need to be provided in a large number like this, could be popularized the application of " stored value card ", and produce optimum Industrial interaction.But, be made with so very large potential safety hazard.Due to a large amount of honesty and credibility of providing POS machines and can not guaranteeing the businessman of all POS of having machines, business trust investigation and actuarial cost are very high.According to the non-contacting feature of radio-frequency card, bad businessman can take public place to POS machine, in the unwitting situation of user, and " theft " user's fund.In order to prevent by the fund of noncontact theft stored value card; someone produces " cutting ferrule ", when radio-frequency card is put into after cutting ferrule, and shielded radio frequency signal; stored value card can not be used in noncontact, protected the safety (ZL02294137.1 shielding protective cover for intelligent card) of stored value card.But, so also losing radio-frequency card ease of use, user can not put into card bag and realize the work of bus card-reading; But card must be taken out and could be used from cutting ferrule.
For solving same safety problem, " ZL201120302380.4 has the contactless IC card of electromagnetic signal protective effect " patent documentation has proposed to shorten the solution of noncontact distance.For solving same safety problem, " ZL02132981.8 non-contact type safety card " patent documentation proposes to solve with a kind of " switch " problem of safe handling.But the electromagnetic performance of this scheme is bad, so " ZL200720149171.6 non-contact card " and " 200710099282.5 1 kinds non-contact card and control method " thereof, patent documentation have been announced an improvement project.In a word, all these existing solutions, in ensureing safe handling non-contact card, abandon or have weakened a major advantage " noncontact " of non-contact card.User can not pay in the situation that " not taking out " card, and when this swipes the card payment in popular traffic, this shortcoming becomes and can not stand.
In fact, businessman can be divided into " credit businessman " and " common businessman ".Here in " common businessman ", may have the assailant of this payment system, they can obtain unlawful interests by transformation POS and other means.The noncontact characteristic of radio-frequency card, making can noncontact " theft ".For credit businessman, as MTR or public transport company, can not in an organized way transform POS machine and steal; Steal and can not obtain economic interests and employee transforms POS machine.So can suppose that Zhe Lei credit businessman can not transform POS and go to obtain unlawful interests.Public transit system is due to needs fast transaction, fast card-reading and pass through fast, so must make full use of the noncontact advantage of radio-frequency card.And noncontact stored value card is in the time of the use of common businessman, obviously low than public transport company to requiring fast; And it is higher than public transit system to the requirement of fail safe.
Like this, we wish that no-contact electronic wallet is retained in the ease of use of public transit system, the fail safe while simultaneously ensureing to use in businessman.While use in credit businessman so, user experiences and preferably keeps completely constant; For example can no-contact electronic wallet not taken out to bag, utilize non-contacting feature to pay.But, while payment in common businessman, stored value card must be taken out and carried out contactless payment.
In order to narrate patent of the present invention, we first narrate prior art.Certification is to carry out between authenticating device and subscriber equipment, and object is the identity that these two equipment of guarantee are confirmed the other side each other.Current authentication method has symmetrical password authentication and asymmetric cryptography certification; Also there is numerous authentication protocols.Using more authentication protocol in stored value card field is symmetrical password authentication agreement.The implication of symmetrical password authentication is: in authenticating device, have key S1, in subscriber equipment, there is key S2, by a series of information exchanges and symmetric cryptographic algorithm, if authenticating device and subscriber equipment are all confirmed S1=S2, represent to authenticate to pass through, then further carry out information transmission, command routing and information and return.For principle of the present invention is described, we adopt mode Fig. 1 of simplification to explain encryption key distribution (hair fastener), identifying procedure and the consumption flow process of present ISO14443.When encryption key distribution (hair fastener), first read No. ID (whole world is unique) of non-contact card 1, and for example, calculate H (ID) with the secret function H of card issuer (MD5), write the symmetrical password authentication key as consumption encryption apparatus 13 in non-contact card 1.When certification, card reader 2 reads No. ID from non-contact card 1, and identical function H carries out identical calculating H (ID) during with hair fastener, if this result be stored in card in to consume the H (ID) of encryption apparatus 13 consistent, just illustrate that this card is the card (stored value card) that card issuer issues.Owing to directly reading the H (ID) of consumption encryption apparatus 13 from card, to compare certification obviously dangerous, and whether so take symmetric cryptography to carry out agreement, to authenticate two H (ID) consistent.Step is as follows: first generate random number RA by the consumption encryption apparatus 13 of non-contact card 1, and be sent to card reader 2; Card reader 2 also produces random number R B, and uses symmetric cryptographic algorithm D to calculate D as key with H (ID)
h (ID)(RA, RB), and be sent to non-contact card 1; Consumption encryption apparatus 13 in non-contact card 1 is by calculating D
h (ID)(D
h (ID)(RA, RB)) obtain RA the RA comparison with previous transmission, whether consistent with non-contact card 1 of the H (ID) that just can confirm card reader 2, and transmit RB after deciphering to card reader 2; Card reader 2 is according to the RB receiving and the RB comparison previously generating, and can confirm that non-contact card 1 is the card that hair fastener tissue sends after consistent, and carry out accordingly and order.More than narration is the simplified illustration that current Bus Card has used technical scheme for many years.In fact, certification can be used asymmetric arithmetic, also can adopt other authentication protocols.But be exactly that authenticating device and subscriber equipment, by a series of information exchanges, reach the object of confirmation in essence.Particularly contactless CPU card is exactly the authentication protocol that adopts other.
According to CPU card and logic encryption card stored value card, we can abstractly be: stored value card is that (logic encryption card MIFARE is a storage area to a memory, CPU card is a wallet file), the read-write (amendment) to stored value card is controlled by two keys.Consume key (depreciation key) and supplement key (increment key) with money.Consumption key and card reader, by certification, just can be used consumption key to consume the work of withholing.Supplement key and card reader with money by certification, just can use and supplement key with money and carry out the work of supplementing with money of stored value card.
So we simplify prior art to be discussed as: no-contact electronic wallet comprises: wallet device, consumption key device, increment key device and non-contact communication device.Use non-contact communication device, after no-contact electronic wallet and card reader are by certification, use consumption that key the carries out wallet device work of withholing of consuming.Here no-contact electronic wallet and card reader, by certification, can be used consumption key to authenticate (prior art), also can use other keys and other authentication modes.
In addition, use non-contact communication device, after no-contact electronic wallet and card reader are by certification, use is supplemented key with money and is carried out the increment work of wallet device.Here no-contact electronic wallet and card reader, by certification, can be used and supplement key with money and authenticate (prior art), also can use other keys and other authentication modes.
Can reference about the patent documentation of this respect: Chinese patent literature " 200680022821.9 use the method and system of contactless payment in transit system ", " 200710099282.5 1 kinds non-contact card and control method " thereof, " methods of 201010533245.2 1 kinds of symmetrical password authentications ", " 201010578562.6 1 kinds strengthen the method and system of stored value card safety ", " 201010578566.4 1 kinds strengthen the safe method of card ", " 201110083946.5 1 kinds of payment system and methods of payment based on contactless smart card ", " 201010534863.9 contactless payment method and systems based on stored value card, mobile terminal ", above mentioned all patent documentations such as " ZL02132981.8 non-contact type safety cards " are all the background papers that this patent is realized, in order to save the length of patent specification, applicant using the specification of above-mentioned all patent documentations all as the part of present patent application, represent these application documents to have been write to this specification.
