S32, client and computing machine carry out in the mutual process, and every interval certain hour sends the indicator signal that the expression client is in mode of operation to the main control module 51 of USB key.
S33, main control module 51 detect whether receive this indicator signal at intervals, if do not receive, then start the second timing submodule 562, pick up counting, and get into step S34, if receive, explain that then client is in mode of operation, get into step S36.
S34, judge module 53 judge that client that the second timing submodule 562 calculates do not have duration that mode of operation continues and whether surpass preset client and do not have the maximum time that mode of operation continues; If surpass; Then the switching condition that switches to park mode is satisfied in explanation; Then get into step S35, otherwise, step S36 got into.
S35, judge module 53 send to handover module 54 and switch indication, and handover module 54 switches to park mode with USB key, gets into step S37.
S36, USB key continue to maintain mode of operation, and continuation and PC carry out normal communication, return step S33.
S37, judge module 53 judges whether be used to receive the button 55 that the user switches is pressed, if, then satisfy the switching condition that switches to mode of operation, get into step S38, otherwise get into step S39.
S38, judge module 53 send to handover module 54 and switch indication, and handover module 54 switches to mode of operation with USB key, returns step S33.
S39, USB key continue to maintain park mode, can't carry out normal communication with PC.
With USB key is example, does not receive the lasting duration of transaction operational order with intelligent code key simultaneously and surpasses preset the 3rd threshold value as switching condition, and the control method of this intelligent code key is specially:
S41, USB key receive on the computing machine through interface module 52; USB key powers on, initial work; USB key accomplishes after the initialization; Main control module 51 begins to accept the transaction operational order, carries out encryption and decryption and handles, and the client that is installed on the USB key on the computing machine begins to carry out alternately with computing machine.
S42, main control module 51 in real time or the compartment of terrain detect whether receive the transaction operational order that computing machine transmits, as not, then start the 3rd timing submodule 563, pick up counting, get into step S43, in this way, then get into step S45.
S43, judge module 53 judge that main control module 51 that the 3rd timing submodule 563 calculates does not receive duration that the transaction operational order continues and whether surpasses preset USB key and do not receive the maximum time that the transaction operational order continues; If surpass; Then the switching condition that switches to park mode is satisfied in explanation; Then get into step S44, otherwise, step S45 got into.
S44, judge module 53 send to handover module 54 and switch indication, and handover module 54 switches to park mode with USB key, gets into step S46.
S45, USB key continue to maintain mode of operation, and continuation and PC carry out normal communication, return step S42.
S46, judge module 53 judges whether be used to receive the button 55 that the user switches is pressed, if, then satisfy the switching condition that switches to mode of operation, get into step S47, otherwise get into step S48.
S47, judge module 53 send to handover module 54 and switch indication, and handover module 54 switches to mode of operation with USB key, returns step S42.
S48, USB key continue to maintain park mode, can't carry out normal communication with PC.
Above content is the further explain that combines concrete embodiment that the utility model is done, and can not assert that the practical implementation of the utility model is confined to these explanations.For the those of ordinary skill of technical field under the utility model, under the prerequisite that does not break away from the utility model design, can also make some simple deduction or replace, all should be regarded as belonging to the protection domain of the utility model.
