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...
متن کاملThreshold Encryption into Multiple Ciphertexts
We propose (T,N) multi-ciphertext scheme for symmetric encryption. The scheme encrypts a message into N distinct ciphertexts. The knowledge of the symmetric key allows decryption of the original message from any ciphertext. Moreover, knowing T + 1 ciphertexts allows efficient recovery of the original message without the key, and without revealing the key as well. We define the security property...
متن کاملOn Classification of Bivariate Distributions Based on Mutual Information
Among all measures of independence between random variables, mutual information is the only one that is based on information theory. Mutual information takes into account of all kinds of dependencies between variables, i.e., both the linear and non-linear dependencies. In this paper we have classified some well-known bivariate distributions into two classes of distributions based on their mutua...
متن کاملStatistical Distributions in Mobile Communications Using Multiple Scattering
A new model utilizing multiple scattering replaces the traditional subdivision of the total fading into a slow lognormal and a fast Rayleigh component. The distribution agrees well with experimental results from a forest and an urban environment. It is shown that part of the slow fading in general may not be due to shadowing, but rather the slow variation of the coupling between scatterers, whe...
متن کاملStatistical Physics, Information Theory and Cloud Droplet Size Distributions
Specification of cloud droplet size distributions is essential for the calculation of radiation transfer in clouds and cloud-climate interactions, and for remote sensing of cloud properties. Despite the effort and progress made over the last few decades, a number of vital issues remain unsolved. For example, 1) It is well known that observed droplet size distributions are generally much broader...
