Digital entry lock with keypad and smart cards
This project is a very secure entry system for your house or some other protected area.
For entry it uses a PIN code in combination with Java Card™ smart card which performs a challenge-response scheme with triple DES encryption (192 bits long keys). It also has internal real-time clock and all entries through this system are dumped via RS232 port to a PC. It is built around a Keil MCB2130 development board but there is also a full schematics for LPC2138 ARM microcontroller so it can work as a stand-alone system.
It sure seems to provide better protection than those high security locks as we can see here.
