Embodiment
A kind of compound encryption apparatus provided by the present invention and this device share the method for display screen and button, effectively reduce power consumption.Compound encryption apparatus comprises intelligent code key and dynamic token, referring to accompanying drawing, first the method for the shared display screen of compound encryption apparatus and button is elaborated.
Step 10: intelligent code key sends wake command by serial ports with low speed baud rate.
Dynamic token is when resting state, in low frequency operation.When intelligent code key wants to show the operations such as data or scanning button, first by serial ports, with low speed baud rate, to dynamic token, send one " wake command ".Described low speed baud rate is 1200bit/s, low speed baud rate matches with " wake command ", is pre-stored within intelligent code key and dynamic token, in addition simultaneously, hereinafter described high speed baud rate is 38400bit/s, is pre-set in intelligent code key and dynamic token equally simultaneously.
Step 20: dynamic token stops dormancy, enters interrupt service routine.
Dynamic token receives after above-mentioned " wake command " by low speed baud rate, stops resting state, enters serial intermit service routine.
Step 30: dynamic token determines whether wake command.
Dynamic token inside prestores the identifying code of " wake command ", when it receives after " wake command " sending by low speed baud rate, by identifying code, verifies, if be verified, judge that " wake command " that receive is correct, enter step 40, otherwise, enter step 60.
Step 40: dynamic token sends and wakes acknowledgement command up with high speed baud rate, arranges and wakes sign up simultaneously.
Dynamic token self mode of operation is set to high frequency mode, and with high speed baud rate, sends " waking acknowledgement command up " to intelligent code key by serial ports, represents from resting state, to be waken up, and arranges simultaneously and wakes successfully sign up.
Intelligent code key receives " waking acknowledgement command up " that dynamic token is beamed back, verify, know that dynamic token is waken up, and then intelligent code key sends " shaking hands successfully " order with high speed baud rate to dynamic token again, dynamic token receives after described " order of shaking hands ", verify, after being verified, with high speed baud rate, beam back " acknowledgement command of shaking hands " to intelligent code key, by intelligent code key, verified, be verified and represent normally transceiving high speed baud rate of dynamic token.So far dynamic token is waken up effectively.Otherwise, when intelligent code key, do not receive within a certain period of time " acknowledgement command of shaking hands " of dynamic token, represent that dynamic token breaks down in receiving high speed baud rate process, is reported to the police by intelligent code key.
Step 50: adopt high speed baud rate to communicate by letter between intelligent code key and dynamic token, share LCD display and button to realize intelligent code key.
Step 60: dynamic token continues dormancy.
Figure 2 shows that the principle schematic of apparatus of the present invention, intelligent code key inside comprises: USB module 11, and connect by USB interface and host computer, and use and receive signature command or data.In addition, 11 of described USB modules, also for obtain electric energy from main frame when being connected with main frame, are intelligent code key power supply.
Command analysis module 12, is connected with described USB module 11, for parsing signature command or data.
Intelligent code key control module 13, be connected with described command analysis module 12, receive after signature order, control connected enciphering and deciphering algorithm module 14, when encryption and decryption processing is carried out in signature order, and control connected first communication module 15 and export signature command or data after processing to dynamic token.
Dynamic token inside comprises: second communication module 25, is connected with described first communication module 15 by serial ports.
Dynamic token control module 21, is connected with second communication module 25, for signature command or the data according to receiving, controls relevant key response and/or the display module 24 of connected key-press module 23 execution and carries out data demonstration.
Dynamic password algoritic module 22, is connected with dynamic token control module 21, for generating dynamic password according to internal algorithm.
Intelligent code key and dynamic token are realized and being waken up by interconnective first communication module and second communication module.Concrete, the connection diagram of the second communication module 25 in the first communication module in intelligent code key 15 and dynamic token as shown in Figure 3.
First communication module 15 comprises and wakes control unit 151 up, and connected the first memory cell 153 and first serial 152 respectively.When waking control unit 151 up, receive after outside enabled instruction, control first serial 152 with low speed baud rate (1200bit/s) output " wake command ", described " wake command " is one group of particular code, matches with low speed baud rate, is pre-stored in the first memory cell 153.
Wake control unit 151 up and receive " waking acknowledgement command up " that dynamic token feeds back, and verify, be verified rear control serial ports and to dynamic token, send " order of shaking hands " with high speed baud rate (38400bit/s), same, " order of shaking hands " is one group of particular code.
Further, after waking control unit 151 up and receiving " acknowledgement command of shaking hands " that dynamic token feeds back and be verified, represent that dynamic token has been waken up and has communicated by letter normally, wakes control unit 151 up and will wake successful information up and be sent to intelligent code key control module 13.
In described the first memory cell, also store " order of shaking hands " matching with low speed baud rate in 153, and the identifying code of described " waking acknowledgement command up " and " acknowledgement command of shaking hands ".
Second communication module 25 comprises and wakes response unit 251 up, and connected second serial 252, wakeup unit 253 and the second memory cell 254 respectively.
Wake response unit 251 up and receive " wake command " and verify, after being verified, controlling wakeup unit 253 dynamic tokens and be set to wake up successfully sign, and control second serial 252 with high speed baud rate output " waking acknowledgement command up ".
When described wake response unit 251 up and receive " order of shaking hands " and be verified after, control second serial 252 with high speed baud rate output " acknowledgement command of shaking hands ".
In described the second memory cell 254, store " waking acknowledgement command up " and " acknowledgement command of shaking hands " of matching with high speed baud rate, and the identifying code of described " wake command " and " order of shaking hands ".
The foregoing is only preferred embodiment of the present invention, in order to limit the present invention, within the spirit and principles in the present invention not all, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
