The Digital Watermarking Techniques Applied to Smart Grid Security

Power supply in the 21st century is facing more and more challenges, e.g., environment protection, energy shortage etc, such that the techniques related to power supply imminently need to be promoted. Complying with the development of green and lowcarbon economy, the concept of Smart Grid has been proposed. By and large, Smart Grid may be regarded as an important application of the techniques of wireless sensor networks and Internet of Things etc in power grid. Smart Grid should be a complicated integrated system with high security, which involves many aspects, e.g., the security of power generation equipments, the security of power transmission equipments, the security of data communications, and so on. Nonetheless, Smart Grid is an open and inclusive system, which makes it unsafe inevitably.
