Abstract
It is expected that there are a variety of energy resources to be jointly operated by the power system in the future. Through jointly operating all types of energy resources via the Internet, Energy Internet is a promising solution to increase energy efficiency. However, the increasing integration of energy resources inevitably imposes challenges in secure communication in the Energy Internet. Resourceful and reliable communication with high Quality of Security Service (QoSS) are crucial to the success of information exchange in Energy Internet. In this light, we advocate a new identity-based key bootstrapping protocol to support energy resources integration and operation, and satisfy the increasing requirements in QoSS. The proposed scheme enables a component to verify the identities of other components and ensure the authenticity and integrity of messages for key bootstrapping, which supports an identity-based communication paradigm for unicast and multicast communication. A system model is defined, and the identity-based communication paradigm is applied to address communication security concerns in real-time. The security and performance analyses show that the proposed scheme is superior to existing schemes.
