....systems, and specify security properties, in our attempt to show systems secure. We might look at them as transition systems, or write them in a process algebra such as CSP[6] or CCS[7] In such a form we may be able to use an automatic verification tool, such as FDR[5] or the Security Checker[4] , to prove or disprove our security properties. Given a process P that we want to show secure (i.e. without undesirable information flow) we can partition its alphabet into disjoint subsets H and L. These subsets represent the available actions of a high and low level user respectively. If we ....
....as indistinguishable if they are weakly bisimilar. Once again we require the low level user s view of the system should be unaffected by whatever actions the high level user may take. Definition 4.1 (BNDC) E 2 BNDC , 8 Pi 2 EH ; E n H B (E j Pi) n H . An additional property was proposed in [4] Strong Bisimulation Strong Nondeterministic Non Interference (SBSNNI) BNDC is difficult to deal with since it requires composition with every high level process Pi, and no static characterisation is known. SBSNNI was proposed as a sufficient condition for BNDC which avoids universal ....

.... engineers should become acquainted with in the future to certify their products (e.g. security protocols) As we will show in the next sections, the CoSeC tool has been obtained by modifying the Concurrency Workbench [14] Part of the material contained in this Section has been published in [26, 32, 25]. 4.1 Input Output and Architecture The inputs of CoSeC are concurrent systems expressed as SPA agents. The outputs are answers to questions like: does this system satisfy that specific security property . The structure of CoSeC is described in Figure 17. In detail, the tool is able: to ....
