Implementation of Cryptographic Algorithm for Secure Wireless Communication

We are surrounded by embedded systems and we use them for various applications. Wireless technology is advancing with a great boom. The integration of wireless communication with embedded system is the latest trend following around. This brings a necessity to take the security measures into consideration as the wireless medium is an unsecured medium. The data which is being communicated needs to be made secure. One of the best methodologies is to implement cryptography for encrypting the data to be sent over the wireless medium. In this paper we have shown the communication between an embedded system and an Android based smartphone using the Bluetooth layer. We have implemented Advanced Encryption Standard (AES) for securing the data.
