Cloud computing will be a main information infrastructure in the future;it consists of many large datacenters which are usually geographically distributed and heterogeneous. How to design a secure data access for cloud computing platform is a big challenge. In this paper, we propose a secure data access scheme based on identity-based encryption and biometric authentication for cloud computing. Firstly, we describe the security concern of cloud computing and then propose an integrated data access scheme for cloud computing, the procedure of the proposed scheme include parameter setup, key distribution, feature template creation, cloud data processing and secure data access control. Finally, we compare the proposed scheme with other schemes through comprehensive analysis and simulation. The results show that the proposed data access scheme is feasible and secure for cloud computing.

A memory enhanced DNSGA-II algorithm for dynamic multi-objective optimization

ICIC Express Letters 2012年第7期6卷 1839-1844页

Although dynamic non-dominated sorting algorithm II (DNSGA-II) is a well-known dynamic evolutionary multi-objective optimization algorithm, it lacks memory ability. For this reason, we propose a memory enhanced DNSGA-II algorithm (denoted by DNSGA-II-DM). Specifically, a non-dominated set-based memory scheme (NSMS) is designed to reuse past useful information. In the NSMS, whenever there is an environmental change, a bunch of non-dominated individuals are stored into a memory pool by a sample procedure and a store procedure. The past optimal solutions stored in the memory pool are reused to rapidly respond to the new change by a retrieve procedure. In addition, a differential evolution operator is introduced as a new search engine to replace the original genetic operator of DNSGA-II. Simulation results on three benchmark test problems demonstrate that DNSGA-II-DM is able to converge better and find a better spread of solutions than DNSGA-II. © 2012 ICIC International.

IEEE International Conference on Cloud Computing Technology and science (CloudCom)

作者： Wei-Tek Tsai Wu Li Babak Esmaeili Wenjun Wu Department of Computer Science and Technology INLIST Tsinghua University Beijing China School of Computing Informatics and Decision Systems Engineering Arizona State University Tempe AZ USA State Key Laboratory of Software Development Environment Beihang University Beijing China

This paper proposes key SaaS (software-as-a-Service) design strategies for those SaaS systems that run on top of a commercial PaaS (Platform-as-a-Service) system such as GAE (Google App Engine)[1]. Specifically, this paper proposes a model-based approach for customization, multi-tenancy architecture, scalability, and redundancy & recovery techniques for GAE. The ACDATER (Actors, Conditions, Data, Actions, Timing, Events, and Relationship) model is used for various features, and then automated code generation is used to generate code based on the model specified. Simulation can be performed to ensure correctness before deployment.

For creating educational systems, each developer usually applies different approaches to specific situations, including advanced software engineering techniques. In the case of systems that provide interactivity-intense assignments, problems during their development include difficulties to manage component repositories and the absence of a systematic process to support code reuse. Interactive Learning Modules (iLM) are systems designed in this context, which also provide key functionalities to facilitate the teacher's work. To address the problems faced during their development, a Domain engineering is proposed to build iLM. In order to define the iLM software family, this paper presents the core features of existing systems, describes the method used to produce an application framework and how to instantiate it. Restructuration of existing iLM using the proposed Domain engineering is reported with initial high gains in productivity and system quality. Copyright © 2012, Australian computer Society Inc.

This paper is devoted to the modeling problem of hypersonic vehicle with significant couplings. An integrated approach is developed to analytically model the dynamics of hypersonic vehicle, in which the effects of variable mass, spherical rotating earth, and couplings among the sub-models are considered. Furthermore, a preliminary analysis is conducted using the general data of a hypersonic vehicle. The simulation results show that the maximum of the Coriolis force can reach values up to 7.02% of the vehicle weight, and that the thermal load determined by the nonuniform aerodynamic heating and the properties of the structure has a significant influence on the elastic deformation.

In this paper, the H_2 optimal state-feedback control problem is investigated for discrete-time Markov jump systems subject to periodic coefficients and multiplicative noise. First of all, an exhaustive analysis is pursued to set up an H_2 performance criterion (H_2 norm), which can be characterized by the periodic solutions of two generalized Lyapunov equations. Based on the obtained H_2 norm, the H_2 optimal state-feedback controller is designed in terms of the stabilizing solution of a discrete-time generalized Riccati equation with periodic coefficients. Moreover, this stabilizing solution can be computed efficiently by the available iterative algorithm.
