Design of electronic trick lock based on single chip device
Abstract
In order to improve the security and safety of personal data,this paper
introduced a new designing method of electronic cipher locks by the use of AT89C52
single-chip processor.It can be set up some cipher code,saved files and prevent from
decoded the code.The software design adoption the design thought from top to bottom,
to make the system toward wear distribute type turn to the direction development of
small, strengthen the system and can expand the stability and circulate Test the result
enunciation, various functions of this system are already all request of this design.
Keywords: trick lock; delay input; unencryptable
