Cryptography based secure multipath routing protocols in wireless sensor network: A survey

Wireless sensor network collects the information from insecure environment. The Wireless sensor node has limited power and energy. Sensor network uses a different routing mechanism for collecting the data from sensor nodes. Multipath routing protocol uses multiple paths to collect the data from different nodes and transfer the data to base station. It improves the security, reliability and fault tolerance. In this paper, we review the cryptography based multipath routing protocols for securing the data in wireless sensor networks. The normal cryptography techniques cannot implement directly in the Wireless sensor network due to less power and energy factors. In the recent research results shows, the security can be improved using modified cryptographic algorithms in the sensor network. This paper collects the cryptography based secure multipath routing protocols and analysis based on energy and security properties.
