Conventional approaches to manage and control security seem to have reached their limits in new complex environments. These environments are open, dynamic, heterogeneous, distributed, self-managing, collaborative, international, nomadic, and ubiquitous. We are currently working on a middleware platform focused on the industrial needs, UBIWARE. UBIWARE integrates Ubiquitous Computing with Semant...

security is one of the most important human needs. researchers believe that the need for security has a strong and close relationship with the physical characteristics of the environment and people’s satisfaction. to study the relationship between security and environmental (physical and social) satisfaction, ‘’cpted’’ approach and its principals in design and environmental planning and urban l...

With hacking attempts, the cost of security breaches, and the importance of defensive computer security in general all on the rise, strong firewalls are more relevant than ever. At the same time, demands for software diversity and increasingly complex network layouts make evaluating adherence to a unified security policy especially difficult. In this paper, I propose a method of uniformly valid...

Using a heterogeneous agent, life-cycle model of Social Security claiming, labor supply and saving, we consider the implications lifespan inequality for reform. Quantitative experiments show that welfare is maximized when baseline benefits are independent lifetime earnings, payroll tax cap 50% larger than its current level, claiming adjustments reduced. The system would maximize in “2050 demogr...

In this study, Co (III) salen complex was synthesized and immobilized onto the surface of Fe3O4@SiO2 magnetic nanoparticle. The heterogeneous nanocatalyst was characterized by different techniques including X-ray diffraction (XRD), Fourier transform infrared spectra (FT-IR), thermogravimetric analysis (TGA), transmission electron microscopy (TEM), nitrogen adsorption−desorption isotherm (BET), ...

Assessing security-related risks in software or systems engineering is a challenging task: often, a heterogeneous set of distributed stakeholders create a complex system of (software) components which are highly connected to each other, consumer electronics, or Internet-based services. Changes are frequent and must be handled efficiently. Consequently, risk assessment itself becomes a complex t...

wireless sensor networks (wsns) have many applications in the areas of commercial, military and environmental requirements. regarding the deployment of low cost sensor nodes with restricted energy resources, these networks face a lot of security challenges. a basic approach for preparing a secure wireless communication in wsns, is to propose an efficient cryptographic key management protocol be...

With the development and application of SOA technology, security issues of Web services based on heterogeneous platform have become increasingly prominent. The security of SOAP message is of great importance to Web service security. In order to solve the security issue of heterogeneous platforms, a security processing model named SIMSA (Security Interactive Model based on SOAP and Authenticatio...
