LPC2138 Security System
Checkpoint Charlie is a security system that features an effective access control terminal based on LPC2138 microcontroller. The project uses Java Card smart card for user-authentication program and performs a challenge-response scheme using a symmetric cryptographic algorithm for optimum reliability. Activity at the terminal is logged and can be transmitted remotely via an RS-232 interface. The system is favorable to using ID cards with magnetic stripes, which are easier to counterfeit than a smart card.
The project is built around a Keil MCB2130 demonstration board, and includes all the necessary external resources required to work as an access control terminal. Designer Carlos Cossio
