Security and Privacy Support for Data-Centric Sensor Networks
Abstract

demand for efficient data dissemination/access techniques to find relevant data from within a sensor network has led to the development of Data-Centric Sensor (DCS) networks where the sensor data instead of sensor nodes are named based on attributes such as event type or geographic location.

However, saving data inside a network also creates security problems due to the lack of tamper resistance of the sensor nodes and the unattended nature of the sensor network.

Abstract:

In this correspondence, we analyze the vulnerabilities of biometric authentication protocols with respect to user and data privacy. The goal of an adversary in such context is not to bypass the authentication but to learn information either on biometric data or on users that are in the system.We elaborate our analysis on a general system model involving four logical entities (sensor, server, database, and matcher), and we focus on internal adversaries to encompass the situation where one or a combination of these ent ....etc

Gen2-Based RFID Authentication Protocol for Security and Privacy
Abstract

EPCglobal Class-1 Generation-2 specification (Gen2 in brief) has been approved as ISO18000-6C for global use but the identity of tag (TID) is transmitted in plaintext which makes the tag traceable and clonable. Several solutions have been proposed based on traditional encryption methods, such as symmetric or asymmetric ciphers, but they are not suitable for low-cost RFID tags. Recently, some lightweight authentication protocols conforming to Gen2 have been proposed. ....etc

Abstract
With the rising of wireless technologies, a lot ofwireless devices have started to reach the domestic domain.Most of them are intended to simplify common tasks avoidingthe use of cables. Home users buy wireless devices because oftheir simplicity and because they are way more practical. Butfew people think of their data privacy and security. They feelsave behind their home walls without knowing that anyonewill be able to listen to their wireless traffic without notice. Isour privacy compromised? Are our home connectionssecured? ....etc

Abstract
RFID is an upcoming technology which is becoming popular due to its non line of sight operation. While there are many advantages associated with an RFID system, due to its wireless nature there is also a threat to user privacy and security. The consumers using an RFID device can be tracked and knowledge about the products they use can also be obtained. Hence, there is an urgent need to ensure adequate privacy and security of RFID systems. In this report, various methods are discussed to ensure RFID privacy. In particular Hash Chainin ....etc

SECURITY & PRIVACY IN WIRELESS LAN


Introduction


This presentation will describe the need for wireless intrusion detection, provide an explanation of wireless intrusion detection systems.

WLANs should employ a security solution that includes an intrusion detection system(IDS). Even organizations without a WLAN are at risk of wireless threats and should consider an IDS solution


Intrusion Detection System(IDS).

privacy:A study of privacy needs of various architectural spaces

INTRODUCTION
Privacy is the ability of an individual or group to seclude themselves or information about themselves and thereby reveal themselves selectively.
The boundaries and content of that is considered differ among cultures and individuals, but share basic common themes.
Physical Privacy could be defined as preventing “intrusions into one’s physical space or solitude”.
Preventing intimate actor one’s body from being seen by others for the purpose ....etc
