A Wireless Sensor Network (WSN) consists of spatially distributed autonomous sensors to cooperatively monitor physical or environmental conditions, such as temperature, sound, vibration, pressure, motion or pollutants. Trust in networks may be defined as the degree of belief or confidence about the nodes on the past interactions and observations. So trust becomes a major issue for reliable communication in WSN under constraints. We propose a trust worthy framework for WSN that considers challenges of the system and focus on the collaborative mechanism for trust evaluation.

1. INTRODUCTION:
The sensor nodes are deployed randomly in the environment to detect the events and send the information back to the base station or the cluster head. Sensor nodes are of limited resources, limited computation and communication capabilities deployed in the environment [1]. Security plays an important role in the sensors deployed in the hostile environments. The sensed data must be protected to ensure the confidentiality. In unattended environments, the sensor nodes are prone to attacks ranging from simple physical attacks to convoluted analysis. The resource constrained sensor nodes are easy to attack and hard to protect from the hackers. New kinds of security management have been proposed for open environments like sensor networks. Trust developments in the network have been hinted as good security mechanism for resource constrained wireless senor networks. Trust and reputation management system is an effective approach in open and distributed environment to improve the security, to support decision making process and for node collaboration. Developing the trust worthy network makes th...

...nd optimum energy consumption ensures trust worthiness in the ad hoc network environment. The trust value in the mobility model of the node is calculated based on the optimum energy consumption during mobility of the node and the selection of the mobility model based on the application requirement. The frequent change of velocity for the mobile nodes makes the intruders hard to trace its region.
3. CONCLUSION:
We have introduced the framework for trust management for key issues in wireless sensor networks. The proposed framework of the trust management in sensor networks may be integrated into many real time applications. The design of the trust management in WSN must be taken into the account with diverse needs including reliability and security. In future, we are planning to deal with more attributes like accuracy, scalability, and fault tolerance of the network.

Trust is “a psychological state comprising the intention to accept vulnerability based upon positive expectations of the intentions or behavior of another “(Rousseau, 1998).
Trust is the one thing in this world that lots of people desire. Who wants to have any type of relationship without trust? It is not something that should be automatically given though, trust has to be earned. People should not automatically trust just because they know them or have been knowing them for a while.
The rapid progress of embedded MEMS (micro-sensing technologies) and wireless communication has made wireless sensor networks possible. Such an environment may have many wireless nodes which are inexpensive; each node is capable of collecting, storing and processing environmental data, and communicating with neighboring nodes. These sensors are connected with wires in the past but tod...

Wireless local area networks (WLANs) have the potential to improve the flexibility, productivity, and the quality of work life of an enterprise (Sage Research Staff, 2001). Berean Institute is a typical two year college with about a staff of sixty eight employees and 250 students per semester. Berean teaches cosmetology, barbering and the latest software and hardware technology, which is located in Philadelphia, Pennsylvania. Berean currently has two locations in the Philadelphia area and using a Local Area Network (LAN).
It has been demonstrated that a number of interoperable systems must be implemented to fully protect a network; a strategy known as Defense in Depth. Due to the multitude of security devices and device categories available, it can be very difficult to identify the correct tools for meeting security goals. Using the Defense in Depth strategy will require an understanding of the interactions between devices occuring within the network.
Trust is defined in Webster’s Dictionary as “firm belief in the reliability, truth, ability, or
Local Area Networks also called LANs have been a major player in industrialization of computers. In the past 20 or so years the worlds industry has be invaded with new computer technology. It has made such an impact on the way we do business that it has become essential with an ever-growing need for improvement. LANs give an employer the ability to share information between computers with a simple relatively inexpensive system of network cards and software. It also lets the user or users share hardware such as Printers and scanners. The speed of access between the computers is lighting fast because the data has a short distance to cover. In most cases a LAN only occupies one or a group of buildings located next to each other. For larger area need there are several other types of networks such as the Internet.
ABSTRACT : This paper describes the basic threats to the network security and the basic issues of interest in designing a secure network. it describes the important aspects of network security. A secure network is one which is free of unauthorized entries and hackers. INTRODUCTION

What is trust? Is trust essential for the way we live our everyday life? Trust is a quality or condition of being trustworthy; loyal; reliable. I think trust is an essential way of life because you cannot make a relationship, friendship, a business, or an organization if there is no foundation. Part of that foundation is trust and loyalty because you should be able to depend, rely, and trust others that they will do exactly what is right for them and you. Trust can be broken so quick, it is scary, because once trust is broken it is a lot harder to gain back then when you first gained trust in someone. This relates to my life because my trust with my dad was alerted going into my freshman year.
This paper is going to discuss wireless security from a broad view where I will go into why exactly wireless security is so important especially today as the ways in which we are communicating is changing dramatically. From there I will discuss the multiple wireless securities that are available to give a better understanding of the options given. Then I will go into why exactly not protecting your wireless can be so dangerous with some descriptions on the most dangerous wireless attacks out there today. Finally I will then discuss how we can better prepare for these types of attacks with a synopsis on several effective security methods that will help to ensure data is securely passed and kept hidden.
This chapter provides an overview of cryptography concept. It`s required to encrypt and maintain confidentiality of the information to be transmitted over the network. This is achieved through cryptography. Cryptography plays a vital role in securing the information when transmitted across the network. It helps in maintaining the integrity of the information stored on the network. Thus, security is one of the important concepts to be explored in the world of network security.
Due to the demand for the internet to be fast, networks are designed for maximum speed, rather than to be secure or track users (“Interpol” par. 1). The adage of the adage.... ... middle of paper ... ...
