( X , Y , Z ) is an ensemble of independent random triples, each distributed according to some probability distribution p ( z , y, z) . Two legitimate users, PX having X and Py having Y , communicate in order to agree on a joint key while keeping it almost unknown to an eavesdropper Pz who knows Z . Communication is conducted over a noiseless channel according to a predetermined protocol. Pz he...

Before proving the theoretical results in this paper, we first present following lemmas used in the proof. Lemma 1. There exists a constant c that only depends on µ and d, such that for all γ > 0 and b signals {x i } b i=1 , the following holds with high probability: sup w∈S d

Why is randomness useful? Imagine you have a stack of bank notes, with very few counterfeit ones. You want to choose a genuine bank note to pay at a store. However, suppose that you don’t know how to distinguish between a “good” bank note and a “bad” one. What can you do? Well, if you pick a bank note at random, you will be lucky with high probability (here the probability of picking a good ban...

Abstract Carbon dioxide removal (CDR) features heavily in low-carbon scenarios, where it often substitutes for emission reductions both the near-term and long-term, enabling temperature targets to be met at lower cost. There are major concerns around scale of CDR deployment many risk that anticipated future could dilute incentives reduce emissions now, a phenomenon known as mitigation deterrenc...

wireless communication is the major form of connection nowadays. in most cases it exploits the benefits of the spread spectrum techniques to overcome channel introduced corruptions like doppler residual frequency, noise, interference and jamming. these techniques also enhance the security and quality of the link. using long spreading pseudo-noise codes provides further security for the link tho...

In this paper, we consider an optimization problem in networks with storage servers for providing multimedia service. The design involves assigning communication link capacity, sizing the multimedia servers and distributing di erent types of content at each server, while guaranteeing an upper limit on the individual end-to-end blocking probability. We consider alternate methods for obtaining th...
