A mobile ad-hoc network (MANET) is a wireless network such that nodes are move dynamically in network. In network layer so many attacks but introduce only collaborative black hole attack a group of black hole node easily employed against routing in mobile ad-hock networks called collaborative black hole attack. In this paper we introduce trusted AODV routing protocol which trust value calculate using...
Security of secret data has been a major issue of concern from ancient time. Steganography and cryptography are the two techniques which are used to reduce the security threat. Cryptography is an art of converting secret message in other than human readable form. Steganography is an art of hiding the existence of secret message. These techniques are required to protect the data theft over rapidly...
In this paper, we present an overview of existing intrusion detection techniques for DDoS attacks. All these algorithms are described more or less on their own. Intrusion detection system is a very popular and computationally expensive task. We also explain the fundamentals of intrusion detection system. We describe today's approaches for intrusion detection system. From the broad variety of efficient...
