Fig. 2 is a kind of mobile terminal structure schematic diagram that the embodiment of the present invention proposes;
Fig. 3 is the structural representation of a kind of mobile terminal that the present invention proposes;
Embodiment
Self-contained fiscard cannot be utilized to carry out the problem of consuming for solving mobile terminal in prior art, the present invention proposes a kind of electronic data processing method, in existing mobile terminal, set up the control unit producing pending electronic data, be provided with in the safety chip of data cell the authentication ' unit increased for interactive information in the terminal simultaneously.
Based on the mobile terminal after improvement, as shown in Figure 1, realization flow is as follows for electronic data processing method of the present invention:
S101, described authentication ' unit receives the electronic data processing request that described control unit sends, and pending electronic data information is carried in described electronic data processing request.
Before this step, authentication ' unit and control unit need to set up communication port, and carry out certification to the legitimacy of control unit.Meanwhile, set up communication port between each data cell in control unit and described safety chip, and by each data cell, certification is carried out to the fail safe of control unit.
S102, described authentication ' unit generates initialization directive, and described initialization directive is sent to the data cell in described safety chip, to make initialization directive described in described data cell identification and session key generation.
Based on the passage between control unit in S101 and authentication ' unit and each data cell, the communication channel of the communication port between self and described data cell and self and described control unit is merged into virtual combination passage by authentication ' unit, and by described virtual combination passage, described initialization directive is sent to described data cell.
It should be noted that, if only have individual data unit in current safety chip, so initialization directive directly can be sent to this data cell in safety chip by authentication ' unit, if but when there is multiple data cell in current safety chip, in order to avoid there is the situation that target is obscured, also carry the mark of pending data cell in electronic data processing request, initialization directive can be sent to data cell corresponding with this mark in safety chip by such authentication ' unit.
S103, described authentication ' unit receives the session key information that described data cell returns, and generates electronic data processing instruction according to described session key information and described pending electronic data information.
Concrete, in this step, electronic data processing instruction comprises two kinds of different content-forms, and the generating mode of its correspondence is as follows:
(1) authentication ' unit generates safe packet MAC by described session key information, and using the described pending electronic data information after being encrypted according to described session key and described safe packet MAC as described electronic data processing instruction;
(2) authentication ' unit generates safe packet MAC by described session key information, and using described pending electronic data information and the described safe packet MAC after being encrypted according to described session key as described electronic data processing instruction.
Correspondingly, session key information can be session key itself, or key dispersion factor.Wherein, key dispersion factor at least should comprise data cell in order to produce the random number of described session key, also can comprise the preset parameter of data cell on this basis simultaneously.
S104, described electronic data processing instruction is sent to described data cell by described authentication ' unit, resolves described electronic data processing instruction and process described pending electronic data information to make described data cell according to described session key.
After the electronic data processing instruction in step S103 is received by data cell, data cell uses session key to decipher the pending electronic data information after encrypting in described electronic data processing instruction, and the safe packet MAC in electronic data processing instruction is verified, if the verification passes, namely data cell performs the operation corresponding with described pending electronic data information.
In addition, after electronic data processing instruction is sent to described data cell by authentication ' unit, authentication ' unit also will receive the response message that described data cell is replied, and carries the message MAC of data cell in this response message; Wherein, described message MAC is that described data cell generates according to described session key after performing the operation corresponding with described pending electronic data information.
Wherein, data cell is specially the fiscard in described safety chip, and safety chip at least comprises with Types Below: SIM card, embedded SE card or SD card.
In order to set forth technological thought of the present invention further, now in conjunction with concrete application scenarios, technical scheme of the present invention is described.For the mobile terminal example sketch shown in Fig. 2, because improvement of the present invention is control unit and SIM card, other parts therefore in this mobile terminal are omitted at this.Wherein.In card, increase a consumer unit, be used for realizing storage key, fiscard certification and consumption dependent instruction composition and resolve, the function such as the logical process of fiscard certification and consumption.Meanwhile, mobile phone increases a control unit, be used for realizing setting up the communication port between consumer unit and fiscard, to forward between consumer unit and fiscard the functions such as information, User Interface such as instruction, the fiscard card number obtained on blocking.
After unit is provided with, specific embodiment flow process is as follows:
(1) control unit selects a fiscard to pay, and set up the passage playing consumer unit, consumer unit can carry out certification to control unit, to ensure the request for legal control unit sends.
(2) control unit is established to the passage of fiscard 2, and fiscard 2 can carry out certification to control unit, and to ensure the request for legal control unit sends, the passage to consumer unit and the channel connection to fiscard get up by control unit.
(3) request of deducting fees is dealt into consumer unit by control unit, needs the mark of carrying fiscard and the amount of money that will pay in request.
(4) the deduct fees request of consumer unit to control unit processes, and the discernible initialization directive of assembling financial card application, the passage set up by control unit, sends to fiscard 2.Fiscard, after receiving initialization directive, produces the session key of this transaction, and this key is used for certification and the encryption of whole consumer sale.Fiscard, by generating random key dispersion factor, informs consumer unit by response.Like this, just identical session key can be calculated respectively between consumer unit and fiscard 2.
(5) consumer unit generates fee deduction instruction, and the session key that in instruction, content can adopt back to generate is encrypted, and carries a safe packet MAC, and MAC calculates and also adopts session key.After being delivered to fiscard 2, fiscard 2 uses session key to be decrypted, and verifies message MAC.If passed through, then complete this locality and deduct fees, and generate oneself a message MAC, use session-key computation, message MAC is carried in response message, returns to consumer unit.
(6) in the response message that returns fiscard of consumer unit, MAC verifies, verify, result of deducting fees issues control unit, presents result by control unit.
By applying above technical scheme, control unit and authentication ' unit is set up respectively in mobile terminal and the safety chip of himself, enable authentication ' unit carry out the certification of electronic data according to the designated data unit in the electronic data processing request of control unit and safety chip with mutual, and then make data cell complete the respective handling of pending electronic data information.Achieve and by the software of mobile terminal, hardware information is wherein processed, improve the integrated degree of mobile terminal.
