Communication based train control (CBTC) system is based on mobile communication and overcomes fixed blocks in order to increase track utilization and train safety. The data communication system (DCS) between trains and wayside equipment is a crucial factor for the safe and efficient operation of CBTC system. The dependability under various transmission conditions needs to be modeled and evalua...

We present two generic formal security models for operating systems of multiapplicative smart cards. The models formalize the main security aspects of secrecy, integrity, secure communication between applications and secure downloading of new applications. The first model is maximally abstract, whereas the second extends the first by adding practically relevant issues such as a structured file ...
