Perfect Secrecy Using Compressed Sensing
In this paper we consider the compressed sensing-based encryption and
proposed the conditions in which the perfect secrecy is obtained. We prove when
the Restricted Isometery Property (RIP) is hold and the number of measurements
is more than two times of sparsity level i.e. M \geq 2k, the perfect secrecy
condition introduced by Shannon is achievable if message block is not equal to
zero or we have infinite block lengthComment: 3 page
MR-BART: Multi-Rate Available Bandwidth Estimation in Real-Time
In this paper, we propose Multi-Rate Bandwidth Available in Real Time
(MR-BART) to estimate the end-to-end Available Bandwidth (AB) of a network
path. The proposed scheme is an extension of the Bandwidth Available in Real
Time (BART) which employs multi-rate (MR) probe packet sequences with Kalman
filtering. Comparing to BART, we show that the proposed method is more robust
and converges faster than that of BART and achieves a more AB accurate
estimation. Furthermore, we analyze the estimation error in MR-BART and obtain
analytical formula and empirical expression for the AB estimation error based
on the system parameters.Comment: 12 Pages (Two columns), 14 Figures, 4 Tables
