According to one embodiment of present invention, operating system 152 is arranged a transaction payment module 1522, adds transaction payment function in the mobile terminal 100 thus.Particularly, by Keyboard management method and related hardware design, control the input that same set of keyboard comes executive utility and payment cipher, come switching and the management of mobile terminal 100 pairs of transaction payment functions.Design proposed by the invention is introduced in detail below with reference to Fig. 2 and Fig. 3.
As shown in Figure 2, the mobile terminal 200 being suitable for carrying out transaction payment function mainly comprises: primary processor 210, keyboard 220 and safety chip 230.Further, safety chip 230 comprises judging unit 232 and ciphering unit 234.According to an embodiment of the invention, keyboard 220 is divided into two regions: cryptographic key panel 222 and non-cryptographic key panel 224.Wherein cryptographic key panel 222 is connected with safety chip 230, and non-cryptographic key panel 224 is directly connected with primary processor 210.Particularly, cryptographic key panel 222 comprises such as numbers and symbols key (as digital 0-9, *, #), " confirmation " key, " cancellation " key, non-cryptographic key panel 224 comprise volume key, top table face (Home) key, power switch key, for starting the scan function key of bar code scanning function.
Such cryptographic key panel 222 and non-cryptographic key panel 224 are just controlled by different modules: the input being controlled cryptographic key panel 222 by safety chip 230, but not 224, cryptographic key panel is directly connected to primary processor 210, by its drived control, ensure the safe reliability paid.
The process flow diagram of the Keyboard management method 300 according to Fig. 3, the method starts from step S310.In step S310, suppose when user have purchased certain commodity needed delivery operation time, it is Anywhere medium that the scene wherein paid can occur in market, restaurant, supermarket and family, user directly inputs payment cipher on keyboard 220, in response to the input of user, keyboard 220 produces press key message.According to an embodiment, the second press key message press key message that keyboard 220 produces being divided for the first press key message produced by code keypad district 222 and produced by non-cryptographic key panel 224.
Subsequently in step s 320, the judging unit 232 in safety chip 230 will judge whether the application that current mobile terminal is just performing is in transaction payment operator scheme.According to an embodiment, the operator scheme residing for the application that mobile terminal 200 is performing is divided into transaction payment operator scheme and nontransaction delivery operation pattern, and is sent the instruction entering or exit transaction payment operator scheme by operating system 152.
Judging unit 232 can such as by maintenance one about the list of application relating to transaction payment operation, judge whether the application that just performing is in transaction payment operator scheme.Or, be applied in when entering transaction payment interface and can notify judging unit 232.If the application that this mobile terminal 200 is just performing is in transaction payment operator scheme, easily expect, current press key message is the first press key message from cryptographic key panel 222, so subsequently in step S330, the first press key message from code keypad district 222 is sent to ciphering unit 234 by judging unit 232, is encrypted the first press key message received by ciphering unit 234.According to an embodiment, store multiple encryption algorithms in safety chip 230, such as symmetric key encryption algorithm: DES Cipher, Advanced Encryption Standard AES; Asymmetric-key encryption algorithm: public key encryption algorithm RSA; And randomizer RNG etc.Therefore the algorithm be encrypted the first press key message can be symmetric key encryption or asymmetric-key encryption algorithm.
Subsequently in step S340, the first press key message after encryption can be sent to primary processor 210, by its certification to complete delivery operation in the mode of asynchronous serial communication (UART) by safety chip 230.
On the other hand, as step S350, if the judging unit 232 in safety chip 230 judges that the operator scheme residing for current application is nontransaction delivery operation pattern, such as user performs other application (such as answer/make phones without payment transaction function with mobile terminal, send note), although or perform the application of supporting transaction payment function but this application is not in transaction payment operator scheme (as user searches commodity in this application), ciphering unit 234 so in safety chip 230 can not be encrypted the first received press key message, and directly send it to primary processor 310.
In addition, if press key message is the second press key message from non-cryptographic key panel 224, then this press key message is directly transmitted to primary processor 210.
Like this, adopt a set of keyboard 220, judge that the operator scheme residing for current application determines whether being encrypted the press key message in cryptographic key panel 222 according to judging unit 232, user both can complete some traditional application operatings of mobile terminal, as called, internet searching etc., transaction payment function can also be performed.By the handover management to keyboard 220, not only achieved the simple and convenient, simultaneously but also ensured pay safe and reliable of operation.
