Abstract:With the in-depth research of CPS (cyber physical system), the security problems of CPS are gradually attracted extensive attention. How to verify the security of space and time inconsistency of CPS has become a research hot spot. A hybrid AADL (architecture analysis & design language) modeling and model transformation method for CPS is proposed to solve this problem. Firstly, the time and space description capability of AADL behavior annex is extended, and Hybrid AADL (hybrid architecture analysis & design language) is proposed. Secondly, the differential equation and the position description are introduced into the process algebra. Thirdly, the hybrid AADL is transformed into HP-TCSP. Finally, the effectiveness of the proposed method is verified by an example of aircraft anti-collision system.
