Hardware Efficient Crypto-Coder Systems for Wireless Channels

ABSTRACT

Wireless channels form an integral part of communication systems nowadays. The data transmitted through these unreliable wireless channels bring in the issues of data security and data errors due to noise. This is because of the random errors that occur during the transmission of data and data mishandling by unauthorized person. Accuracy, security, and reliability of data transfer can be achieved by merging channel coding techniques with cryptographic methods. In this paper, a hardware efficient crypto-coder system for handheld devices, which incorporates an optimized ROM based convolutional encoder with modified Authenticated Lightweight Encryption is proposed. The system performance is evaluated in Additive White Gaussian Noise channel. Comparison of the proposed system with the existing one shows a hardware efficiency of 42%, Clock Domain Power reduction of 16%, and power reduction of 28%. The system simulation is validated in Xilinx 14.2 ISE and implemented in Xilinx Spartan-3E FPGA.
