Enhancement in DiDrip protocol to securely disseminate data in wireless sensor network

Security and confidentiality of data is very much essential while deploying a wireless sensor network. Depending on the environment in which network is deployed; configuration parameters of network nodes need to be updated time to time. This can be achieved using data discovery and dissemination protocols. DiDrip is the first data discovery and dissemination protocol that has been designed by taking different security vulnerabilities in mind. The protocol expedites network owner to authorize multiple network users having different privileges for simultaneous and direct dissemination of data into the network nodes. This paper proposes a new technique to minimize packet loss during data dissemination using DiDrip protocol and provide high security to wireless sensor network. RSA and Diffie Hellman key exchange algorithm are used as methods of encryption.
