INTRODUCTION The key to the success of real-life applications for mobile

devices is a mechanism assuring secure communicationand proper collaboration among all participant entities.

This security is provided by policy enforcementmechanism. node1

SCOPE To ensure fair and secure communication in MANETs,

proper communication policy must be provided.

This project presents the design and implementation of apolicy enforcing mechanism based on trusted executionmonitor built on the TPM.

Before allowing a node to join a network , SATEM verifiesits trustworthiness of enforcing the required policies.

If any policy is violated SATEM disconnects the node.

OBJECTIVE To build a monitor on Trusted Platform Module(TPM)

which verifies the trustworthiness of enforcing therequired policies.

PRINCIPLES FOLLOWED: Secure routing: Improve the reliability and robustness of

AODV using Packet Leashes.

Justified sharing: Every mobile node has to serve or relay atleast 1 request from others after posting 3 queries to thenetwork.

Fair game: Each gaming node is free to join any of the nteams. But once it joins one, it can not join another team

without first withdrawing from the current team.

TRUSTED MULTI-TIER NETWORK

A tier for each purpose and a tier upon tier.

Satem: The foundation of trust

Components:

Trust agent(satem) is used to control policy managementamong the nodes in the kernel.

Trust evaluator used to control policy management at

application level.

Protocols: System commitment Includes kernel binary and the

modules it may load. Service commitment Includes entire code stack of the

service.

Tier Manager

The tier manager is an application that allows the node to

create, join and merge into a tier

Protocols: Join: To join an existing application tier.

Protocol:

Merge: merging two related tiers for flexibility and simplicity.

EnforcerAn enforcer is any softwarethat can enforce the tier policy. In the simplest form, the tier

application itself has built-in capabilities of enforcing certainpolicies and can be the enforcer.

CONCLUSION Policy management in ad hoc networks is complex and

tedious.

Using proposed system the policy management ismade reliable and protected.
