Abstract: As wireless sensor networks (WSNs) expand their application areas and become more widely utilised, the need for security in these networks becomes unavoidable and essential. The fundamental properties of wireless sensor networks do, however, impose limits on sensor nodes. These constraints include limited energy, processing capabilities, and storage capacity, among other things. The purpose of this article is to offer an outline of the problems about privacy and security that are linked with sensor networks. It has been shown that asymmetric key cryptography is not suitable for wireless sensor networks. However, in light of the development of new energy-efficient sensor nodes such as TelosB and others, researchers are exploring and assessing the influence that public key cryptography has on wireless sensor networks. At the time of data transmission, the proposed work achieves a 9.67% improvement in security, and it achieves an 11.38% improvement in security.

Keywords: secure data aggregation in WSN; concealed data aggregation; homomorphic encryption.
