Abstract:
A Mobile ad hoc network (MANET) sharing a wireless channel among collection of
mobile nodes without any centralized control. Due to dynamic topology of network
set a secure path for data transfer from one node to another node is difficult. The
nodes which exist inside the network cannot be always trusted. During transmission
Security of routing information is major concern. There are several routing protocols
are available for secure data transfer from one node to another but still they venerable
from verity of attacks. Many techniques are available for secure routing information
but still security is not fully satisfied. An attempt has been made to improve the
security during transmission in MANETs with minimum overhead. RSA public key
encryption provide secure routing of data and can defend against attacks like black
hole, grey hole.
