The use of self organized wireless technologies called as Mobile Ad Hoc Networks (MANETs) has increased and these wireless devices can be deployed anywhere without any infrastructural support or without any base station, hence securing these networks and preventing from Intrusions is necessary. This paper describes a method for securing the MANETs using Hybrid cryptographic technique which uses RSA and AES algorithm along with SHA 256 Hashing technique. This hybrid cryptographic technique provides authentication to the data. To check whether there is any malicious node present, an Intrusion Detection system (IDS) technique called Enhanced Adaptive Acknowledgement (EAACK) is used, which checks for the acknowledgement packets to detect any malicious node present in the system. The routing of packets is done through two protocols AODV and ZRP and both the results are compared. The ZRP protocol when used for routing provides better performance as compared to AODV.
