DESIGN AND IMPLEMENTATION OF HYBRID CRYPTOGRAPHY INMANETS

Abstract

An effective way of short range communication
are Mobile ad Hoc Network (MANET),but due to their t
inbuilt characteristics such as dynamic topology, minimal
physical security, constrained functionality, which all
makes them vulnerable to both passive and active attacks
in network. In such environment, verifying the nodes
authenticity and achieving data confidently is a
challenging task and therefore, a great deal of research
has been dedicated to securing routing and management
of keys. A novel concept has been presented in this paper
for designing an efficient security solution that can protect
ad hoc network from heterogeneous attacks. The Ad hoc-
On Demand Distance Vector (AODV) routing protocols
has been optimized for ad hoc network, among all other
protocol AODV is efficient for path establishment and this
paper has improvised the protocol further using
cryptographic technique, a solution that provides most of
the security requirement. We have applied AODV protocol
and the proposed cryptographic solution with
amalgamation of AES, ECC, RC5, SHA-2 (AERS) to
generate the asymmetric and symmetric keys to secure
communication and routing along with integrity and
confidentiality over cipher text in MANETs on secure
AODV (SAODV). The proposed cryptographic technique
is implemented through NS3 network simulation. The
performance of the proposed solution was evaluated
through energy consumption, packet delivery ratio of
black AODV, SAODV, throughput and
