MULTILEVEL ADAPTIVE SECURITY SYSTEM by Hongwei Li Recent trends show increased demand for content-rich media such as images, videos and text in ad-hoc communication. Since such content often tends to be private, sensitive, or paid for, there exists a requirement for securing such information over resource constrained ad hoc networks. In this work, traditional data security mechanisms, existing ...

Smart grid concept is introduced to modify the power grid by utilizing new information and communication technology. Smart grid needs live power consumption monitoring to provide required services and for this issue, bi-directional communication is essential. Security and privacy are the most important requirements that should be provided in the communication. Because of the complex design of s...

as a response to a growing interest in rfid systems such as internet of things technology along with satisfying the security of these networks, proposing secure authentication protocols are indispensable part of the system design. hence, authentication protocols to increase security and privacy in rfid applications have gained much attention in the literature. in this study, security and privac...

A confined program is one which is unable to leak information to an unauthorized party or modify unauthorized resources. Confinement is an essential feature of any secure component-based system. This paper presents a proof of correctness of the EROS operating system architecture with respect to confinement. We give a formal statement of the requirements, construct a model of the architecture’s ...

Security is “freedom from risk or danger”, while computer and data security is “the ability of a system to protect information and system resources with respect to confidentiality and integrity”. Defining biometrics system security is difficult, because of the ways biometric systems differ from traditional computer and cryptographic security [40]. Implicit in all definitions is the concept of a...

Software is an important resource. It contains and controls data and other resources. Thus measures must be taken to protect that data and resources. Thus Software Metrics are measurement of some properties of a piece of software or its specifications. Metrics are very important in Software Quality Measurement. Since Tom De Marco rightly stated “You can’t control what you can’t measure.” Softwa...

F rom cars to cell phones, video equipment to MP3 players, and dishwashers to home ther-mostats—embedded computers increasingly permeate our lives. But security for these systems is an open question and could prove a more difficult long-term problem than security does today for desktop and enterprise computing. Security issues are nothing new for embedded systems. In 2001, Peter Shipley and Sim...

A formal model for description of passive and active timing attacks is presented, studied and compared with other security concepts. It is based on a timed process algebra and on a concept of observations which make only a part of system behaviour visible. From this partial information which contains also timing of actions an intruder tries to deduce some private system activities.
