Detailed description of the invention
Below by accompanying drawing, technical solution of the present invention is described in detail, but protection scope of the present invention is not limited to described embodiment.
Embodiment 1 :A kind of embedded cryptography based on microcontroller is locked, its structural representation as it is shown in figure 1, include code keypad, electric control lock, for the central control unit that inputoutput data is controlled with to the input code translator that verifies of password.
Central control unit uses chip LPC1115, by I/O interface and described code keypad two-way communication.Chip LPC1115 is based on ARMCortex-MO kernel, and high primary frequency 50MHz, on sheet, Flash is 64KB, and on sheet, RAM is 8KB.Therefore, the present embodiment utilizes the high speed kernel of LPC1115, processes the data of password, and processing speed is fast, and security performance is high.Described chip LPC1115 periphery arranges reset circuit, and the circuit diagram of described reset circuit as shown in Figure 4, arranges hand-operated forced button, if program is made mistakes, running status can be made to return to original state by this button.It addition, described chip LPC1115 periphery arranges transforming circuit, 5V voltage, as it is shown in figure 5, described transforming circuit includes chip AMS1117 and four decoupling electric capacity, is become 3.3V output by the circuit diagram of described transforming circuit.
Central control unit and described code translator two-way communication, described code translator and described electric control lock two-way communication.Confirmed that by code translator the password of input is the most correct, if correct, control automatically controlled coded lock and open, otherwise, be not switched on.Being additionally provided with relay-set between code translator and electric control lock, the circuit diagram of relay-set is as it is shown on figure 3, described relay-set passes through audion as switch, the drive circuit of use Control electric control lock, it is ensured that the sensitive performance of electric control lock.
In order to further ensure that the security performance of coded lock, the present embodiment also includes using chip SIM3000 to realize with SIM R-T unit described in the SIM R-T unit of mobile device interactive information, its circuit diagram is as shown in Figure 2, described SIM R-T unit and described central control unit are by serial line interface two-way communication, by SIM R-T unit, send information to householder, further ensure that safe performance.
