Most of the key exchange protocols have high computational complexity leading complex hardware implementations. Though CA based PAKE is easily realizable in hardware, we observe that it has serious security flaws. In this paper we propose RPAKE, a secure PAKE scheme, basing on the features of reversible cellular automata (RCA).

The PF scheduler in the BS allocates the OFDMA resources to each SS according to their bandwidth request. The EDD scheduler in the SS utilizes the allocated resources according to the packet deadline thus provides QoS guarantee. The proposed system is simulated using C programs and extensive simulation results were presented. The simulation is carried out with varying OFDMA frame size (5 msec, 10 msec) and coding rates (16QAM CTC 1/2, 16QAM CTC 2/3) and the throughput and delay performance is compared.

A power scheduling policy depends completely on the power request patterns of the target applications. The designer of any power scheduling policy has to guarantee that inclusion of her power scheduler in a particular set of applications would never force the system to violate any of its correctness specifications in course of power rationing. In this work, we contribute by designing quantitative temporal specification logic, named PTL, which can express system correctness properties, both functional and power related. Characteristics of this logic is that using it, one can express various power related constraints like peak power bound, temporal patterns of power consumption for a finite computation etc. along with functional temporal constraints. It supports formal performance analysis as well at the architecture level. We have also developed model checking algorithms for this logic. This would help application designers to encode temporal behaviors, both functional and power related, of the individual applications and of the system as a whole and subsequently verify whether inclusion of a power scheduler in the system ever forces any of its components to deviate from its correctness specification","PeriodicalId":122715,"journal":{"name":"2006 Annual IEEE India Conference","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131412745","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper explores FSM in temporal data domain or FTP mining and proposes an efficient algorithm for the same. Existing algorithms for FTP mining are based on a priori's level wise principle. In conventional or transactional data domain, a priori has been proven to suffer from the repeated scans limitation and has been succeeded by several algorithms that overcome the setback. The proposed algorithm eliminates a priori's repeated scans limitation in temporal domain, requiring only two overall scans of the original input.

The system consists of an uncontrolled rectifier and AC controller as the non-linear loads, with an active filter to compensate for the harmonic current injected by the load. The active filter is based on a single-phase inverter with four controllable switches, a standard H-bridge inverter. The AC side of the inverter is connected in parallel with the other nonlinear loads through a filter inductance. The DC side of the inverter is connected to a filter capacitor. The neural PI controller is used to shape the current through the filter inductor such that the line current is in phase with and of the same shape as the input voltage. The spectral analysis of the supply current shows the harmonics produced by the load has been successfully compensated by the active filter. The system is modeled in Matlab Simulink and simulation results prove that the injected harmonics are greatly reduced and system efficiency and power factor are improved","PeriodicalId":122715,"journal":{"name":"2006 Annual IEEE India Conference","volume":"276 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132590193","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The design of any good state estimator necessitates the development of a nonlinear model of the plant.

Hence the energy in the excitation signal is high around these places and these instants play an important role in the perception of speech. This property is exploited in this work to derive the weight function. The linear prediction (LP) residual of the spectral subtracted speech signal is weighted by the weight function to enhance the significant excitation of speech.
