ABSTRACT
Wireless communication is vital during natural calamities, disasters and military operation. In the past
few decades, security in the military operations is exposed to vulnerabilities like sniffing the information
and modifying the data causing havoc in military camps. Consequently military applications required a
secure way to exchange the data and stay away from enemy intrusion. Recent trends in military
operations need a portable way of communicating between the units, quality of service and security to be
full-fledged. However, in Manet mobile entities are prone to various security attacks due to dynamic
changing topology, open medium and inhibited by limited energy, bandwidth and computational power.
The paper addresses the security issues by incorporating the concept of trust and certification authority
to combat the misbehaving entities. Certificate authority employs fuzzy based analyzer to distinguish
between trusted and malicious behavior of nodes by distributing the certificates only to the trusted nodes
and detecting the misbehaving node. The proposed scheme is more secure, reliable and aids to improve
the security in military operations.
