The security of MANET is one of the major problems for researchers and scholars. While using the Trusted Third Party and non Trusted Third Party schemes to provide communication and authentication, it results in lot of security attacks like missing packets, denial of service attacks, modify packets, Theft of nodes, error in packets etc. One of the TTP schemes addressed these issues effectively by issuing certificates on its online basis; however, the scheme suffered overheads in different communication scenarios. Another non-TTP scheme provides an authentication approach in MANETS using key management by the nodes themselves but faced the security problems due to the blind trust being put on the nodes for adding other nodes in the MANET. Both schemes results in weaknesses regarding overheads and security concerns. We are proposing a new secured Certificate Authorized Routing Protocol (CARP) to provide the secured communication in MANET. The CARP model authenticates the nodes using Fourth Generation (4G) services and enables communication after the nodes being authenticated permanently.
