Secure Key Sharing in Mobile Ad hoc Network using Content Invisibility Scheme

In mobile ad hoc network (MANET) privacy protection and efficient use of memory is a challenging task due to mobile and dynamic behavior. Existing schemes provides anonymity, unlinkability and unobservability, but they consume more memory space and also result in computation overhead and communication delay. In our proposed scheme, key is established only between neighbors, which reduce memory storage, computational overhead and communication delay. In our scheme, ID Based Encryption is proposed. By using this scheme we can overcome the internal and external attacks. Also we achieve privacy in terms of anonymity, unlinkability and unobservability.
