A key pre-distribution protocol for node to node and group communication in wireless sensor networks using key pool matrix

Sensor networks have huge demand in various fields like military, environment monitoring, hospitals and many hostile environments. Further, they are also used in application of internet of things where many number of sensors is connected through internet. These applications demand security issues like confidentiality, authentication, integrity, because of their deployment areas and sensitivity of the data. By considering these issues, the key management plays an important role in many information security solutions which are used information protection. The proposed work exploits the various vulnerabilities in the sensor network and addresses various kinds of solutions for vulnerabilities through proposed key distribution scheme. The key generation and distribution implemented using key pool matrix. The comparison and analytical analysis are shown that the proposed work requires less communication and storage space at each sensor. Further, the proposed work can also increase resilience, reduce key compromise and number of revocation operations compared with other schemes.
