Designing the API for a Cryptographic Libraryts safe use and to hinder implementation errors. This is of special interest when the implementation language is celebrated for its qualification to write reliable safe and secure systems, such as Ada..This paper concentrates on the handling of nonces (“number used once”) and on authenticated encryp

Handling Synchronization Requirements under Separation of Concerns in Model-Driven Component-Based Dnt of real-time high-integrity systems. Interpreting Dijkstra’s view in this regard, we seek separation of concerns between the specification of needs (expressed declaratively by the user as requirements and assumptions) and the conception of a demonstrable solution for them (which we want to implem

Formal Goal-Oriented Development of Resilient MAS in Event-Bts goals despite changes, e.g., caused by failures of system components. In this paper we propose a formal goal-oriented approach to development of resilient MAS. We formalize the notion of goal and goal achievement in Event-B and propose the specification and refinement patterns that allow us to gu

Improving the Performance of Execution Time Control by Using a Hardware Time Management Unitcribed here is for Ada 2012 and a GNAT bare-board run-time environment, the principles should be applicable to other languages and run-time systems. The TMU has been implemented as a peripheral unit for the Atmel AVR?32 UC3 series of microcontrollers, and test results from simulation with the synthe

Implementing and Verifying EDF Preemption-Level Resource Control). This protocol has proved problematic both in terms of its language definition and implementation. This paper proposes a means of verifying the implementation of complex language features. It describes a prototype tool that allows a comparison to be made between the output of an executing program

Efficient Constraint Handling during Designing Reliable Automotive Real-Time Systemstware having hard real-time requirements and constraints over how, when and where they execute. The requirements and constraints are essential to the overall systems dependability and safety (e.g. to ensure replicas execute on different hardware). This leads to a complex design space exploration (DS
