A Reconfigurable Architecture for Secure Multimedia Delivery

Abstract

Abstract-This paper introduces a reconfigurable architecture for ensuring secure and real-time video delivery through a novel parameterized construction of the Discrete Wavelet Transform (DWT). This parameterized construction promises multimedia encryption and is also well-suited to a hardware implementation due to our derivation of rational filter coefficients. We achieve an efficient and high-throughput reconfigurable hardware implementation through the use of LUT-based constant multipliers enabling run-time reconfiguration of encryption key. We also compare our prototype (using a Xilinx Virtex 4 FPGA) to several existing implementations in the research literature and show that we achieve superior performance as compared to both traditional CPU-based and custom VLSI approaches while adding features for secure multimedia delivery.

Reconfigurable hardware implementation of a modified chaotic filter bank scheme

“…Alternatively we can break down a (B 1 × B 2 ) bit multiplication into smaller input LUTs. Thus, the LUTs based multiplication can be reconfigured to incorporate any changes in encryption key (Pande and Zambreno, 2010).…”

Hardware Implementation of a Real Time Image Compression

“…DWT cores using the lifting scheme require two or more passes [18,19]. This wavelet core implements the "line-based" DWT similar to that described in that requires only one pass per row/column and each lifting step requires separate multiplication units [20,21]. Provide unique scalable architectures using the line-based lifting scheme method similar to that employed in this thesis to reduce the memory requirements for performing the 2-D DWT [22,23].…”

Performance Evaluation of Video Communications Over 4G Network

“…In LTE-A systems, the bandwidths in both uplink and downlink can go upto 100 MHz, which is achieved by Carrier Aggregation (CA) or aggregation of individual Component Carriers There have been volumes of research in different aspects of multimedia systems, to enhance the performance of mobile video. Hardware architectures have been proposed for mobile video compression and encryption [9][10][11]. Efficient video transmission in cellular low bandwidth scenarios has also been discussed [12][13][14][15][16].…”
