Achieving energy efficiency using novel scalar multiplication based ECC for android devices in Internet of Things environments

In the era of Internet of Things (IoT) infrastructure, Secured information transfer is necessitated between mobile and internet based services in IoT environments. As IoT environment connected to heterogeneous network, they become vulnerable to attacks and hence it is required for secured mechanism for data transfer. Moreover, when secured cryptographic algorithms are employed in mobile phones, battery consumption plays amajor role. The IoT environment associated with proposed algorithm can be used to interlink humans and enable the use of a communication channel to bring forth inter machine interaction. The encryption procedures used here makes sure that the major concerns of authentication uniqueness, confidentiality and privacy of the users are maintained. This implies that the users and the service providers can implement the system security measures that have been proposed. Research is still being conducted to improve the architecture and implementation strategies in a real time environment. In order to solve those issues, this paper proposes a novel scalar point-multiplication which gives low energy consumed snippet based on elliptic curve cryptography (ECC) that provides same level of security and also keeps low energy consumption by speeding up the computation time. The performance evaluation with the key size of 14 and 16 bits reveals that the proposed algorithm can be fast and saves the battery life than the other conventional ECC algorithms.
