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.

Poštovani, hteo bih da na mojoj stambenoj zgradi montiram ovakvu bravu za otvaranje ulaznih vrata. Da li imate u ponudi ovaj modul zajedno sa elektromagnetnom bravom i koliko bi sve to koštalo. Hvala unapred.
