Mobile Ad hoc NETwork (MANET) is a collection of wireless mobile nodes forming a network without using any existing infrastructure. MANET is a collection of mobile nodes along with wireless transmitter and receiver that with each other via a bi-directional links either directly or indirectly. A new intrusion detection system named communicates Enhanced Adaptive ACKnowledgment (EAACK) specially designed for MANETs. It is based on the Digital Signature Algorithm (DSA). To enhance the security in the mobile ad hoc networks, the authors introduce a new approach called hybrid cryptography algorithm that provides integrity, confidentiality and authentication.
