We study a new stochastic multi-player multi-armed bandits (MP-MAB) problem, where the reward distribution changes if collision occurs on arm. Existing literature always assumes zero for involved players happens, but applications such as cognitive radio, more realistic scenario is that reduces ...

We propose a general way of constructing zero-knowledge authentication schemes from actions of a semigroup on a set, without exploiting any specific algebraic properties of the set acted upon. Then we give several concrete realizations of this general idea, and in particular, we describe several zero-knowledge authentication schemes where forgery (a.k.a. impersonation) is NP-hard. Computational...

Secure identification is an important security issue to avoid computer fraud due to masquerading. This can be achieved with zero-knowledge based smart cards. We present very efficient new zero-knowledge schemes in a general algebraic setting. Particular cases of our scheme improve the performance of the Guillou-Quisquater and the Chaum-Evertsevan de Graaf schemes. Our scheme is formally proven ...

A zero-knowledge authentication scheme is a type of authentication scheme, which gives no knowledge beyond the authenticity identifying an entity and is probabilistic than deterministic authentication scheme. This paper proposes Diffie-Hellman and Fiat-Shamir like zero-knowledge authentication schemes on general non-commutative groups. The key idea of our proposal is that for a given non-commut...

This paper proposes a low-complexity scheduling algorithm with opportunistic channel state feedback using zero-forcing dirty paper coding (ZF-DPC) or zero-forcing (ZF). Whereas some existing schemes suffer a delay to update the serving users, the proposed algorithm continues to update the serving users immediately at each opportunistic channel feedback. Due to this dynamic serving user adaptati...

Since the invention of the first idea of digital signatures relied on public key algorithms many properties are added, and numerous novel schemes are developed. Besides this grow, a novel idea in identification schemes relied on public key algorithms is also presented, that is zero knowledge proof of identity. However, along with this development many remarkable schemes for instance the Fiat-Sh...

In the previous two Chapters, we proposed fraction nonconforming nonparametric control charts to monitor process location and process variability. It is also shown that performance of proposed control charts are superior to that of the Shewhart X and sign charts. If process is running in an in-control state for a long period, it will reach in steady-state mode. In order to characterize long-ter...

In this paper, we extract the waterline from synthetic aperture radar (SAR) images to illustrate coastline change in Shanghai, China. Nine ERS-2 and ENVISAT SAR images acquired between 1998 and 2006 were selected and a new land-water classification scheme was implemented to obtain coastline. The results show that the seaward coastline change between 1998 and 2000 is faster in the eastern part a...

Progress in the implementation of state-of-the-art signalprocessing schemes in sonar systems is limited mainly by the moderate advancements made in sonar computing architectures and the lack of operational evaluation of the advanced processing schemes. Until recently, matrix-based processing techniques, such as adaptive and synthetic-aperture processing, could not be efficiently implemented in ...
