In the 21st century, today's smart environment needs secure information i.e. packet transferred from source to destination node in distributed wireless sensor networks. As compared to wire networks distributed wireless sensor network are more susceptible to security attacks due to the shortage of a limited battery lifetime, trusted centralized authority, processing capability, memory and bandwidth, etc. In this paper, they present a proposed idea for a secure packet delivery with help of cryptographic technique in wireless sensor networks. In this paper, they present the challenges and have proposed an integrated comprehensive security that will provide security services for all services of distributed sensor network.
