MAES BASE Efficient Architecture for Real Time Audio

VLSI System Design

During the last decades, information security has become a major issue. Cryptography is playing major role in information and security division. The main aim of the cryptography is to protect the data from unauthorized users or hackers. The concept of cryptography consists of two parts, one is encryption and another decryption. Encryption is a process of converting the plain text to cipher text using some keys. Decryption is a process of converting the cipher text to plain text using the keys. Encrypting and decrypting data have recently been widely investigated and developed because there is a demand for a stronger encryption and decryption which ensures privacy and practically very hard to crack. Cryptography plays major role in fulfilment of these demands. There are several algorithms in cryptography to encode and decode the data based on the key. These algorithms are useful in transmission of messages and data between one user and another. Taking a real time voice as input and it gives to the audio code 97 and the output of this audio codec gives to the FPGA kit. In this kit perform two process encryption and decryption. Here we used MAES algorithm for encryption and the decrypted voice is given to the audio codec 97 and at last we get original voice through output speaker.
