Encryption of Covert Information into Multiple Statistical Distributions

A novel strategy to encrypt covert information (code) via unitary projections into the null spaces of ill-conditioned eigenstructures of multiple host statistical distributions, inferred from incomplete constraints, is presented. The host pdf ’s are inferred using the maximum entropy principle. The projection of the covert information is dependent upon the pdf ’s of the host statistical distrib...

Bit-Serial VLSI Implementation of Vector Quantizer for Real-Time Image Coding

Absrract -Vector quantization (VQ) has emerged as a viable approach for coding speech and image data in the last decade. Various vector quantizers are designed and their performance evaluated during the last few years. The hardware realizations of VQ encoder systems have been designed mainly for real-time speech coding ranging from the use of “off-the-shelf” components to applying VLSI technolo...

A Novel Multiply-Accumulator Unit Bus Encoding Architecture for Image Processing Applications

In the CMOS circuit power dissipation is a major concern for VLSI functional units. With shrinking feature size, increased frequency and power dissipation on the data bus have become the most important factor compared to other parts of the functional units. One of the most important functional units in any processor is the Multiply-Accumulator unit (MAC). The current work focuses on the develop...

Data Hiding in Multimedia Audio using VLSI technology

This paper is devoted to VLSI technology for high security purpose. Textual information is embedded in to an audio using LSB coding and it is encrypted and decrypted by Steganography algorithm. Low bit encoding or Least Significant Bit (LSB) encoding technique is proposed to encode the least significant bit of a host file with a bit of the Steganography data. This method assumes that this alter...

An efficient secure channel coding scheme based on polar codes

In this paper, we propose a new framework for joint encryption encoding scheme based on polar codes, namely efficient and secure joint secret key encryption channel coding scheme. The issue of using new coding structure, i.e. polar codes in Rao-Nam (RN) like schemes is addressed. Cryptanalysis methods show that the proposed scheme has an acceptable level of security with a relatively smaller ke...
