PROJECT TITLE :
Trust Management for Defending On-Off Attacks
A trust management theme can be used to assist an automatic call-creating process for an access control policy. Since unintentional temporary errors are potential, the trust management answer should give a redemption theme to allow nodes to recover trust. But, if a malicious node tries to disguise its malicious behaviors as unintentional temporary errors, the malicious node may be given additional opportunities to attack the system by disturbing the redemption scheme. Existing trust management schemes that employ redemption schemes fail to discriminate between temporary errors and disguised malicious behaviors in that the attacker cleverly behaves well and badly alternatively. During this paper, we have a tendency to present the vulnerabilities of existing redemption schemes, and describe a brand new trust management and redemption theme that may discriminate between temporary errors and disguised malicious behaviors with a versatile style. We have a tendency to show the analytical results of the trust management theme, and demonstrate the advantages of the proposed scheme with simulation conducted in an exceedingly Wireless Sensor Network.
