Information technology has made major strides in the past decade. As results, there have been widespread applications of data storage and transmission. The valuable multimedia information in digital forms, however, is vulnerable to unauthorized access while in storage and during the transmission. Network security and image encryption become important and high profile issues. Image encryption requires manipulating massive amounts of data at high speeds. The use of software in image encryption provides flexibility for manipulation but may not meet some timing constraints. In this paper, we present a novel technique for image encryption using block cipher. The primary concept is based on the implementation of 3-Way encryption algorithm. Experiment results show that our proposed method significantly enhances the security for transmission images over network as well as for storage. Beside the software implementation, we present the hardware implementation of 3-way image encryption algorithm based on FPGA technology. With the flexibility of software implementation and the high performance of microprocessor, FPGA-based cryptosystem is a promising technology for the future network security.
