The power grid is aging and congested and faces new challenges and stresses that put at risk its ability to reliably deliver power to an economy that is increasingly dependent on electricity. i.e. The security of the United States and the way of life of its citizens is dependent on the availability of the North American power grid. Much of the technology currently in use by the grid is outdated and in many cases unreliable. The reliance on old technology leads to inefficient systems, costing the utilities and taxpayer’s unnecessary sums. There is virtually universal agreement that it is imperative to upgrade the electric grid to increase overall system efficiently and reliability.
A growing recognition of the need to modernize the grid to meet tomorrow’s challenges has found articulation in the vision of a Smart Grid. The essence of this vision is “a fully-automated power delivery network that can ensure a two-way flow of electricity and information between the power plants and appliances and all points in between”. To upgrade the grid, and to operate an improved grid, will require significant dependence on distributed intelligence and broadband communication capabilities. The access and communications capabilities require the latest in proven security technology for extremely large, wide-area communications networks. This paper discusses key security technologies for a smart grid system, including public key infrastructures and trusted computing
