Abstract:
Mobile ad hoc networks (MANETs) can be defined as a collection of
large number of mobile nodes that form temporary network without aid
of any existing network infrastructure. there are numbers of attacks that
affect MANET. Mobile nodes without adequate protection are easy to
compromise. It causes congestion sends false routing information or
causes unavailability of services and Challenges in secure
communication.
The researcher compared an Elliptic Curve cryptographic(ECC) and
Rivet-Shami-Adleman(RSA) a mechanism used for secure MANET
And reached the following results ECC uses the lowest key size for
encryption / decryption ,less Time key generation if compared with
RSA , ECC is better throughput and less time jitter and delay where
compared with RSA ,there used ECC is better for secure MANET .
