摘要：
Recently the security has become a major concern in the effort to build the critical infrastructures that must be more reliable, cost-effective and environment friendly. For example, the high-speed back-bone data networks, intelligent transportation systems (ITS), and smart grids, are typical examples of the infrastructures that can be broadly categorized into cyber-physical systems (CPS).
There are just too many challenging issues to secure such systems. For example, what are the major issues in security for CPS, including the typical attacks? How to authenticate the cyber-physical devices dynamically? What security primitives can provide the required message integrity to both control and data applications? How to detect and defense the major attacks against the CPS?
This talk will discuss these critical issues and the possible solutions based on the speaker’s R&D experience in AT&T Bell Laboratories, and several U.S. universities. First, we introduce a new model to describe CPS devices; particularly the general architecture and management protocol stacks are reviewed. We emphasize the communication capabilities of the CPS devices, as compared to the legacy industry devices. Second, we present the available security primitives and mechanisms that can be applied to the CPS, including the technologies for authentication, message integrity, and confidentiality (privacy), and nonrepudiation services. Third, we identify the major threats to CPS are the command and data tampering. More specifically, the threats include Sybil attack, man-in-middle attack, replay attack, selective forwarding, sink-hole attack, worm-hole attack, and even Byzantine attack. We also propose a solution to defense the attacks, i.e., link layer encryption and authentication (LLEA). Fourth, we present our research in answering the challenges. For example, to validate our solution to the security issues in smart grids, we develop an HIL test-bed, which has been supported by NSF FREEDM ERC. Experimental and RTDS simulation results are provided to demonstrate the effectiveness of the proposed solutions. Finally, we summarize the further issues for future research.
