Abstract: A smart grid is an electricity network that uses digital and other advanced technologies to monitor and manage the transport of electricity from all generation sources to meet the varying electricity demands of end-users It possesses demand response capacity to help balance electrical consumption with supply. It is pointed out that there are tenacious economic as well as environmental urgings for the refurbishment of the conventional power systems, and its replacement with a Smart Electrical Power Grid or simply Smart Grid. The main challenges of smart grids, however, are how to manage different types of front-end intelligent devices such as power assets and smart meters efficiently; and how to process a huge amount of data received from these devices. Smart grid is an electric grid which includes a variety of operational and energy measures including smart meters, smart appliances which are used to measure the power consumption of those devices, and it consists of renewable energy resources, and energy efficiency resources which can be used by those devices. In this paper, we propose a cloud computing based framework for big data information and a security solution based on identity-based encryption, signature and proxy re-encryption to address critical security issues of the proposed framework.
