Implementing Digital Signature with RSA algorithm to enhance the data protection in cloud

India which is an agriculture dependent country must pave its way for promoting development of intelligent and smart agriculture system. The emergence of Internet of Things(IoT) technologies has changed various traditional applications to smart home, smart city, smart health, and smart agriculture. Even though Wireless Sensor Networks (WSNs) have seen rapid bloom, securing data in the network is still a challenge. The main objective of a smart agriculture system is to ensure the security of the data that is transmitted over the network and the one which is stored in cloud. A Wearable Environmental Monitoring System (WEMS) is designed with the aim of preventing loss of data and providing secure data communications. IoT data analytics with cryptographic algorithms will increase the protection of cloud data. In this paper, a combination of public key or asymmetric cipher algorithms namely Rivest, Shamir and Adleman (RSA) and Elliptic Curve Digital Signature Algorithm (ECDSA) is proposed.
