Wireless Sensor Network Security Using Certificateless Cryptography

Abstract

Secured and timely transmission of data is always an important aspect for an organization. In the encryption process the failure rate of keys and processing time are directly related with the security of cryptographic model in Wireless Sensor Network (WSN). The use of strong encryption algorithms almost make it impossible for a hacker to get access of node which is being protected by keys. Data security is an essential component of an organization in order to keep the information safe from various competitors. Current aspects of cryptography and need of data security in communication are discussed in the beginning of this thesis. It also covers the various key authentication techniques employed for the data security with their merits and demerits. The work done by the various researchers in the field of cryptography has also been discussed. Observations from literature survey, problem formulation, objectives and research mythology has been formulated to design a new methodology. Then a certificateless cryptographic scheme has been proposed that meets the objectives such as key uniqueness and secure communication. After presenting the proposed schemes, their results and comparison with existing schemes and among each other has been drawn. Finally, conclusions and the future scope of the proposed work have been mentioned.
