AES128/192/256 ENCRYPTION ENGINE FOR BIOMETRIC PROTECTED SERIAL COMMUNICATION SYSTEM

Abstract

In recent years, there are many biometric protected storage devices available in the market, and research has shown more products would be linked to biometrics data in future. In Singapore, our passport has gone biometric, due to its added security purposes. The reason for the need of biometric protection is because the fingerprint of an individual is unique and it can serve as an important key to an individual.

This project is to design and develop a secured communication architecture with Biometric Protected Access over the AES128/192/256 encryption algorithm for data transfers over the serial communication bus. This architecture will serve as a encrypting and decrypting block between a storage device and the host server/terminals, where the key to the encryption/decryption is an individual biometric data, thus giving it better security as only the intended user would have the unique biometric data key (Thumb Print/Palm Print etc) to decrypt the stored data.

The main focus is on the research of AES128/192/256 encryption/decryption algorithm and how to incorporate this algorithm into our design architecture. The report also contain details on how the AES128/192/256 encryption/decryption algorithm is being developed into C++ coding and methods of testing and simulation of the algorithm. A review into Biometric Capturing and USB communication protocol was included in this report. The closing chapter summarize on the main points of the project and also give a reflection of the entire process of the project coursework.
