Wireless systems security

The four traditional, intertwined areas of security are
• secrecy, (or confidentiality or privacy) which involves keeping information out of the hand of unauthorized users,
• authentication, which involves making sure one is communicating with the intended person,
• non repudiation, which deals with signatures, and which ensures that a person cannot go back on his/her earlier communication, and
• integrity control, which deals with ensuring that the received message was not ....etc

ABSTRACT


The internet has been a wide usage in all the fields in the present competitive world. It is being used in the education, research, business and what not, in everything. But providing security for the users information or transactions or any other data in any of the field has become a paramount. This paper gives a vivid picture of E-commerce and the vulnerabilities they are facing in providing a secure system for the users. In other words, how the security attacks are made either by the hackers or the intruders, the ways how the ....etc

Real-time systems play a considerable role in our society, and they cover a spectrum from the very simple to the very complex. Examples of current real-time systems include the control of domestic appliances like washing machines and televisions, the control of automobile engines, telecommunication switching systems, military command and control systems, industrial process control, flight control systems, and space shuttle and aircraft avionics.

All of these involve gathering data from the environment, processing of gathered data ....etc

Abstract— Computational Private Information Retrieval (cPIR) protocols allow a client to retrieve one bit from a database, without the server inferring any information about the queried bit. These protocols are too costly in practice because they invoke complex arithmetic operations for every bit of the database. In this paper, we present pCloud, a distributed system that constitutes the first attempt toward practical cPIR. Our approach assumes a disk-based architecture that retrieves one page with a single query. Using a striping technique, ....etc

HIGHLY DYNAMIC SYSTEMS




INTRODUCTION
Highly Dynamic System (HDS) is a collection of heterogeneous and decentralized nodes in a wireless network. The devices are differing in their size, shape, storage capacity, mobility, connectivity etc. We can add new devices into HDS according to our needs and also remove certain devices that are not working properly from the system. The applications i ....etc
