This document proposes a secure and distributed data discovery and dissemination protocol for wireless sensor networks called DiDrip. Existing protocols have drawbacks in that they use a centralized approach where only the base station can distribute data, and they were not designed with security in mind. DiDrip allows multiple network users to directly disseminate data to sensor nodes with different privileges. It consists of four phases to securely distribute data in a distributed manner: system initialization, user joining, packet preprocessing, and packet verification. The proposed system provides advantages over centralized approaches by allowing direct data dissemination to nodes, increasing security, and improving packet delivery ratio.

All existing data discovery and dissemination protocols suffer from two drawbacks. First, they are based on the centralized approach; only the base station can distribute data items. Such an approach is not suitable for emergent multi-owner-multi-user WSNs. Second, those protocols were not designed with security in mind and hence adversaries can easily launch attacks to harm the network. This paper proposes the first secure and distributed data discovery and dissemination protocol named Did rip. It allows the network owners to authorize multiple network users with different privileges to simultaneously and directly disseminate data items to the sensor nodes. Moreover, as demonstrated by our theoretical analysis, it addresses a number of possible security vulnerabilities that we have identified. Extensive security analysis show did rip is provably secure. We also implement Did rip in an experimental network of resource- limited sensor nodes to show its high efficiency in practice.

DISADVANTAGES OF EXISTING SYSTEM: • Centralized approach • Existing method is in-efficient • Vulnerable to security attacks PROPOSED SYSTEM: • In this project, we propose secure and data discovery and dissemination protocol (DiDrip). DiDrip consists of four phases, system initialization, user joining, and packet preprocessing and packet verification.

If the result is positive, it updates the data according to the received packet. ADVANTAGES OF PROPOSED SYSTEM: • User can send the data directly to the sensor nodes without using the base station • Provide more security for data • Increase packet delivery ratio
