摘要：Current facilities provided by the mobile phone are very diverse, ranging fromthe phone, SMS, camera, music player, all rolled into one. Of course, the mobilephone can also be used as electronic keys to replace the existing analog key atthis time. Usually to open a door lock one must use a key, so to access a lot ofdoors must have a lot of different keys. But if the mobile phone is used as anelectronic key, access control must implement all the keys which are not neededanymore, just with one mobile phone can open a lot of keys. In this thesis, it isdesigned a simulation of electronic keys that uses the mobile phone as a remotecontrol, and the computer as a central controller. Communication betweencomputer and mobile phone uses Bluetooth, while as keys are simulation ofLED lights which are connected to the parallel port of computer. This electronickey system applies access control by using RC4 encryption and MD5 Hashing.This design can turned on / off the LED light that perform as an electronic keysimulation using the mobile phone, and only those who have registered and haveaccess rights that can be turned on / off the LED light. Design modules arecreated using the NetBeans IDE 4.1 and the MySQL database, with someadditional libraries. Library needed is mobility Netbeans 4.1,mysql-connector-java-3.0.9, BlueCove, Bluelet-Benhui. And the mobile phonemust support Java MIDP 2.0 and JSR-82.
