An enhancement of EAACK using P2P ACK and RSA public key cryptography
افزایش EAACK با استفاده از رمزنگاری کلید عمومی P2P ACK و RSA-2019 MANET – Mobile Adhoc Network is a self-configuring network that connected by the number of mobile
nodes with wireless links and it has no fixed infrastructure. In this, each single node can operates as both
a transmitter and receiver. It has been exploited in various applications such as disaster stuck areas, military,
emergency revival etc. Nevertheless, the open intermediate and broad distribution of nodes in
MANET can cause a vulnerable to different malicious attacks and MANET that can operate consistently
even in the being there of inside packet drop attackers can be really challenging. Therefore, we need
to develop Intrusion Detection System to detect the misbehavior nodes during the packet delivery with
acknowledgement for the protection of MANET. In this paper, EAACK (Enhanced Adaptive
Acknowledgment) is developed with Enhanced Interior Gateway Routing Protocol (EIGRP) hybrid protocol
which consists of P2P ACK and RSA algorithm. At present, the network overhead is caused by the digital
signature algorithm if more misbehavior nodes are presented on network. Hence, this proposed
system is applied with EIGRP to reduce the network overhead caused by digital signatures in EAACK,
and P2P (peer-peer) ACK and RSA (named after Ron Rivest, Adi Shamir and Len Adleman) provides more
security to the network. S-ACK (Selective Acknowledgements) cannot differentiate the particular node is
malicious node. Therefore, this proposed system introduces the P2P ACK to detect the misbehavior node
efficiently. Here, RSA can encrypt the session key that creates the key more secure to improve the security
level and P2P ACK use this encrypted key for the acknowledgement. In the P2P ACK, keys are generated by
the RSA and distributed for signing and verifying the acknowledgement packets in advance. This proposed
P2P ACK is used to enhance the detection of misbehavior nodes. The performance of this proposed
method can improve the security level and reduce the routing overhead through the secured
acknowledgement. Keywords: MANET | EAACK | Routing overhead | Security level | RSA | P2P ACK | Intrusion detection systems | Misbehaving nodes detec |
