One of the widely used security mechanism for sensor network is the software-hardware implementation of cryptographic algorithms. If the confidential data is lost as a result of adversary effect, then the whole sensor network is prone to get exposed to the intruder. What we need is a strong mechanism, to protect such sensitive data. In this paper we present a technique where we mask all the intermediate input and output data with some values in order to de-correlate information leaked, if any, so that the original/actual information is not exposed to the attacker. An architecture is proposed which is embedded on the sensor node to incorporate built in security feature at the chip level itself. This is done by the addition of a new hardware component called an LFSR, at the chip level itself, which is capable of generating random numbers to mask the output. As far as the clustering technique used is concerned, we've considered the hierarchical clustering to ease data aggregation.

For leveraging the security level of the systems, it is required to develop an effective and practical methodology for evaluating the adequacy of the designed and/or implemented security counter- measures for a system. We propose a model as a one of the methodologies for evaluating security countermeasures which does not depend on the characteristics of a target system shown by the supporting businesses or the system configuration or the scale. This model consists of required security countermeasures that are well arranged for easy implementing, and required technologies and activities for achieving a target level for every required countermeasures.

Windows registry, a central repository for configuration data, should be investigated for obtaining forensic evidences, since it contains lots of information that are of potential evidential value. Using some forensic tools, forensic examiners can investigate values of windows registry and get information can be forensic evidences. However, since windows registry contains huge amount of values and these values can be modified by users, suspect can hide his secret like password in registry values. In this paper, we discuss the basics of Windows XP registry and extract some registry entries related to forensic analysis. Finally, we show that some countermeasures are needed, listing up consideration items for hiding secrets in registry as suspect's viewpoint.

Networks are protected using many firewalls and encryption software's. But many of them are not sufficient and effective. Therefore an intrusion detection system (IDS) is required that monitors the network, detects misbehavior or anomalies and notifies other nodes in the network to avoid or punish the misbehaving nodes. Numerous schemes have been proposed for intrusion detection and response systems, for ad hoc networks. The ultimate goal of the security solutions for wireless networks is to provide security services, such as authentication, confidentiality, integrity, anonymity, and availability, to mobile users. In this paper, we examine the vulnerabilities of wireless networks and argue that we must include intrusion detection in the security architecture for mobile computing environment. We propose a mIDS (mobile intrusion detection system) suitable for multi-hop ad-hoc wireless networks, which detects nodes misbehavior, anomalies in packet forwarding, such as intermediate nodes dropping or delaying packets. mIDS does rely on overhearing packet transmissions of neighboring nodes. Simple rules are designed to identify the misbehavior nodes. Theproess of identyfing the misbehavior node is carried out by a special node called a monitor node. Periodically monitor node is identified in the network.

According to augmentation about interests for privacy in mobile network over the past few years, researches that provide the anonymity have been conducted in a number of applications. Ad hoc routing protocols with the provisions for anonymity both protect the privacy of nodes and also restrict the collection of network information by malicious nodes. Until recently, quite a number of anonymous routing protocols have been proposed. Many of them, however, do not make allowance for authentication. Thus, vulnerabilities such as modifications to packet data and denial of service attacks can be more easily exploited. In this paper, we propose the anonymous routing protocol also furnishing authentication in the mobile ad hoc network. This protocol supports these anonymity properties which should be provided in ad hoc network. In addition, authentication is also provided by group signature for both nodes and packets during route discovery phase.

Traditional access control disciplines such as RBAC has difficulty in covering open and decentralized multi-centric systems because it has focused on a closed system where all users are known and primarily utilizes a server-side reference monitor within the system. Trust management has relaxed this known user restriction and allowed authorize for strangers based on their credentials. However, trust management has also been found to be lacking because of certain inherent drawbacks with the notion of credential. In this work, a new access control model T&RBAC is presented in this paper. It integrates RBAC and TM. User can be assigned to local roles, also can be assigned to foreign roles based on his credential and local roles. We proof that there is no security constraints in T&RBAC. To some extends, T&RBAC is only a core model and can be extended for specific requirement.

There are many kinds of social networks in existence. To our best knowledge, there is no effort on how to construct a social network jointly from different parties. Thus, there is a need for a proper protocol to both make a collaborative social network feasible between different parties and ensure privacy. We propose a series of protocols to create and interact with a privacy preserving collaborative social networks and evaluate their potential. The protocols are implemented, tested and evaluated.

Organisations have become increasingly dependent on technology in order to compete in their respective markets. As IT technology advances at a rapid pace, so does its complexity, giving rise to new IT security vulnerabilities and methods of attack. Even though the human factors have been recognized to have a crucial role in information security management, the effects of weakness of will and lack of commitment on the stakeholders (i.e., employers and employees) parts has never been factored into the design and delivery of awareness programs. To this end, this paper investigates the impacts of the availability of awareness programs and end-user drive and lack of commitment to information security awareness program design, delivery and success.

It is well known that there is relationship between electromagnetic emanation and processing information in IT devices such as personal computers and smart cards. In this paper, we show how to estimate amount of information that is leaked as electromagnetic emanation and effectiveness of averaging technique. We assume the area between the IT device and the receiver is a communication channel, and we define the amount of information leakage via electromagnetic emanations by its channel capacity. And we also estimate the maximum amount of information which eavesdropper can get via electromagnetic emanation. By using these estimations, we derive the necessary amount of data for effective averaging technique.

In this paper, we consider a problem of monopolistic information management technologies. Most service providers have an access to any information. Even though the information is really a personal data, service providers can access with it merely with the user's first subscription. A collaborative privacy management system (Co- PMS) is suggested to satisfy the requirement. In this scheme, each user will provide ones own privacy policy by using a policy creation interface. The policy negotiation engine performs collaborative process with the certain service's data disclosure policy. This architecture provides more powerful right to each user to access ones own privacy policy and personal information. It also reinforces the security because of diverse privacy policy. It will develop the privacy policy based on security systems. We also expect the encrypted privacy policy to be used as an authentication certification.
