Abstract: The wireless nature of communication and lack of security infrastructure raises several security problems in MANET. So, security routing is essential for mobile ad hoc networks. A number of routing methods have been proposed for security routing. The key idea in our algorithm is to explore key authentication at the time of key sharing. Authentication is performed for key distribution and communication. This paves an integrity and authenticity. Collisions of source and destination nodes are reduced and internal and external attacks are overcome using less cryptographic techniques with less computation steps. Confidentiality is achieved by encrypting the keys. A novel symmetric key sharing method is proposed which emphasises the efficient and secure key sharing and key updates. In our scheme, digital signature and symmetric key combine together and protects the efficiency aspects. Through extensive simulation analysis it is inferred that our algorithm provides an efficient approach towards security and in the mobile ad hoc network.
