Resource Aware Node Authentication Framework for Secure MANET

MANET includes mobile nodes that are linked to each other via a wireless connection without infrastructure. MANET is vulnerable to security attacks because it has no unique characteristics, infrastructure network and multihop communication. Therefore, each node of MANET must be secure and node security can be provided using node authentication technology. Each node of Money contains battery power, bandwidth, memory, and other resources to store the routing information. These resources provided by MANET nodes are limited resources.

To protect MANET, people usually consider the confidentiality (privacy), ease of use, integrity, reliability, nonrepudiation of the target. Due to confidentiality, confidential information on the network never leaks to an unauthorized node. In other words, it is guaranteed not to disclose data to unauthorized party. Due to availability, required network services such as bandwidth and connectivity are made available in a timely manner, and services that authenticate users are not denied. It is to confirm that data is easy to obtain. Consistency ensures that messages or packets sent between nodes are not modified or corrupted. It is to confirm that the data is genuine. Authentication will correctly identify the peer node as the communication partner. Non-repudiation will prevent the sender of the message from accidentally refusing to send the message. That is, the node can not refuse data to be sent at a later time.

The main security issues that need to be addressed in MANET are the secure storage of keys / data in the device, the authentication of the devices that wish to communicate with each other, the establishment of the session key security key between the authenticated devices, It is a hop network. Secure Routing Security means to keep privacy (confidentiality), usability, integrity, nonrepudiation. Security means identifying potential attacks, threats, and vulnerabilities within the system against unauthorized access, use, modification, or destruction. A security attack is an act that jeopardizes or circumvents information security illegally or fraudulently. Attacks may cause data to be changed, released, or rejected

MANET's node mobility has many security problems, and it is different from conventional wired and wireless networks such as open media, dynamic network topology, lack of centralized management, distributed collaboration, functional limitation, explicit circuit absence there is. Types of security attacks Defense The unconstrained nature of MANET wireless media allows an attacker to intercept, insert, and intercept communications. Without adequate security, mobile hosts are easily captured, leaked, and hijacked by malicious nodes. The operation of a malicious node may deliberately confuse the network, causing packet loss throughout the network. Damage includes leaked confidential information, message contamination, and node simulation
