Abstract

In this paper, an Internet of Energy (IoE) solution for providing optimal charging and control of resources in the era of electric vehicles (EVs) with energy trading and security is considered. A blockchain based security solution is presented by considering the IoE as a distributed energy system with internet of things (IoT). However, by inheriting the security concerns of IoTs, IoE also faces the security challenges and is considered here. Hierarchical key generation is used for cryptographic keys, based on lattice constructions. Along with a consensus tailored with Practical Byzantine Fault Tolerance (PBFT), an additional smart contract is also applied for utilization of energy transfer. The presented solution provides transparency, reliability, availability and failure recovery inheriting from the blockchain aspects. To the best of our knowledge, the present study is the first attempt in this direction of IoE-EV interface solutions. The experimental results, comparative analysis and security validation affirm the superiority of the proposed solution over the existing approaches. [ABSTRACT FROM AUTHOR]

Abstract

Objective: To provide secure image to the user within less processing time. Methods: Due to increase in multimedia traffic the intruders become more active to misuse the personal data including images. Therefore it is important to protect the images being shared. Hence in this research, image is encrypted using International Data Encryption Algorithm (IDEA) known as A-IDEA. First the image is divided into different parts and then DWT is applied. Application of Discrete Wavelet Transformation (DWT) results in confusion of pixels i.e. pixels get jumbled due to which it is impossible to depict the original image. Results: This procedure increases security of the image transmission and helps to reduce the computational delay. Conclusion: A new algorithm based on DWT and IDEA for image encryption is proposed which results in less computational and processing delay.
