III. OBFUSCATION OF SMART METER DATA A. Need for cryptography During the process of transmission of information, it is almost impossible to prevent eavesdropping. The transmission of smart meter readings is often done over an insecure channel. The privacy related issues become the focal point determining the future of the smart meter technology. In this paper, we propose a novel method to secure the smart meter readings using the concept of cryptography [15]. Cryptography refers to the art of securing data by adopting mathematical tools to encrypt and decrypt data. It aims at sending information between two parties in a way that prevents the intrusion of a third party. Cryptographic systems are associated with an algorithm as well as a secret value known as a key. Based on the agreement on a shared key between the sender and the receiver, the messages can be confidently send over an insecure channel without being concerned about eavesdroppers. This is because decryption of the information is impossible without the aid of the secret key [12], [9 ]. B. Discrete Cosine Transform Power signal which is procured, has numerous high frequency and low frequency components. The main objective of this paper is to increase the secrecy of the power signal data, which is made feasible by computing the DCT. This transformation converts a signal in time domain to frequency domain. A single spike in time domain of the power signal may appear as many spikes in frequency domain, i.e., a singleShow MoreRelatedLibrary Management204752 Words   |  820 PagesClassification, Tenth Edition Arlene G.
