With reference to figure 1 (b), at the back side of rotation displacement cipher keyboard apparatus of the present utility model, be provided with loudspeaker louver (7), be used for loudspeaker and send information of voice prompt or warning message by it.Draw an order wire from the rear portion of rotation displacement cipher keyboard apparatus of the present utility model and be connected with nine hole serial ports (8), this nine holes serial ports is communicated by letter with the main frame (not shown).
Fig. 2 has shown circuit block diagram and the principle of work according to rotation displacement cipher keyboard apparatus of the present utility model;
According to rotation displacement cipher keyboard apparatus of the present utility model, its circuit mainly comprises main control module, and keyboard load module, communication module, LCD MODULE, voice cue module, data storage spare module and the buzzing alarm module etc. of communication with it.Main control module can adopt band ISP 52 series monolithics of IAP function 256 byte RAM, the above flash program storage of 20K.Whole device is controlled the co-ordination of each module by the software program of single-chip microcomputer inside, finishes password input and uploading operation.The most important thing is, whole device to be stolen a glance at when the client inputs password and is made the client search the key assignments that shows at random easily in order to prevent, on the basis of described modular construction, also provide the solution of the display position random variation that makes key assignments 0-9 in the above.Make when each the use, the display position random variation of these digital 0-9.Described random variation mainly contains dual mode:
1. random sequence mode: by clockwise or counterclockwise from 10 numerals of 0-9 series arrangement, 0 position is at random, then other 9 numerals change with 0 change in location; And password of every input can be provided with to such an extent that rearrange once.
2. out of order at random mode: i.e. the demonstration of 10 digital 0-9 is random arrangement; And password of every input can be provided with to such an extent that rearrange once.
Under above-mentioned dual mode situation, can be subdivided into four kinds of patterns again, available:
(1). random sequence pattern " 1 ": when the input password, can make the random variation of the numeral generation locality on the LCD screen, but 0～9 put in order is constant by " Fn " function key.
(2). random sequence pattern " 2 ": when input all can produce above-mentioned variation by any key during password, promptly when every input one key assignments, all can produce the random variation of key assignments, but 0～9 put in order is constant.
(3). out of order at random pattern " 1 " can make the numeral on the LCD screen produce out of order random variation fully by " Fn " function key when the input password.
(4). out of order at random pattern " 2 ", when input all can produce out of order random variation fully by any key during password, promptly when every input one key assignments, the out of order at random variation that all can produce key assignments.
The random sequence of above-mentioned key assignments and the principle of work of out of order variation at random are described below:
The address space that program is opened up 10 storage unit is as showing that the key assignments zone preserves random number, and and liquid crystal display on display position corresponding one by one.When host computer when in client's operating process, having button to press (or) when keyboard sends order, obtain random number, be kept at and show in the key assignments zone, and on liquid crystal display, demonstrate key assignments.Owing to show that the key assignments display position is one to one on key assignments zone and the liquid crystal display,, just can change the key assignments in the pairing key assignments display position on the liquid crystal display, thereby produce out of order so change the numerical value that shows in the key assignments zone.
The acquisition methods of random number is as follows: the system start-up timer, when host computer when in client's operating process, having button to press (or) when keyboard sends order, read the random number that the numerical value of timer TL0 (1)/TH0 (1) can obtain, perhaps by reading numerical value in the timer as the DPTR pointer of search program memory block, obtain random number in program storage area, these methods can obtain random number.
Preserve the method for random number:
(1). after reading TL1 acquisition random number, judge the parity of random number:
If the random number that a. reads TL1 and obtained is an odd number, then is kept at the liquid crystal display position and shows one to one in the first address in key assignments zone that make current demonstration key assignments regional address add 1 simultaneously, random number numerical value adds 1 reading random number that TL0 obtains.And whether the address of judging current demonstration key assignments zone be the last address that shows the key assignments zone, if random number is then preserved in last address, withdraws from circulation.If not last address, judge that then whether random number adds value after 1 greater than maximal value 9, if greater than maximal value 9, compose with minimum value 0, so circulation, until the address in current demonstration key assignments zone for showing the last address in key assignments zone.
If b. read random number that TL1 obtains is even number, then is kept at the liquid crystal display position and shows one to one in the last address in key assignments zone reading random number that TL0 obtains.Make current demonstration key assignments regional address subtract 1 simultaneously, random number adds 1.And whether the address of judging current demonstration key assignments zone be the first address that shows the key assignments zone, if first address is then preserved random number, withdraws from circulation.If not first address, judge that then whether random number adds value after 1 greater than maximal value 9, if greater than maximal value 9, compose with minimum value 0, so circulation, until the address in current demonstration key assignments zone for showing the first address in key assignments zone.
So promptly obtain the non-complete out of order display mode of out of order pattern 1 and out of order pattern 2.
(2) by reading numerical value in the timer as the DPTR pointer of search program memory block, after in program storage area, obtaining random number, do not judge the parity of random number, show one to one in the key assignments zone but directly be kept at, and then go to gather random number, judge whether equal with the value of the former random number that obtains with the liquid crystal display position, if equate, do not preserve, continue to gather random number, until unequal.If unequal words are preserved random number in next one demonstration key assignments zone, so circulation has been preserved unequal separately random number in showing the key assignments zone, promptly obtain the complete out of order display mode of out of order mode 3 and out of order pattern 4.
Change the changeless shortcoming of conventional keyboard key assignments according to rotation displacement cipher keyboard apparatus of the present utility model, adopt liquid crystal display, the key assignments on its liquid crystal display produces at random, shows at random.The out of order technology that has adopted this key assignments completely random to produce is further improved the security performance of client password.
