Interface between SysML and Sequence Planner Language for Formal Verification

Design and formal verification of DZMBE+

In this paper, a new broadcast encryption scheme is presented based on threshold secret sharing and secure multiparty computation. This scheme is maintained to be dynamic in that a broadcaster can broadcast a message to any of the dynamic groups of users in the system and it is also fair in the sense that no cheater is able to gain an unfair advantage over other users. Another important feature...

Formal Verification of Complex Systems based on SysML Functional Requirements

As modern systems continue to increase in size and complexity, they pose increasingly significant safety and risk management challenges. A model-based safety approach is an efficient way of coping with the increasing system complexity. It helps better manage the complexity by utilizing reasoning tools that require abstract models to detect failures as early as possible during the design process...

A Formal Universal Systems Semantics for SysML

OMG SysML1 is a general purpose systems modeling language adopted by OMG in May, 2006. Used for specifying, analyzing, designing, and verifying complex systems; it provides graphical representations with a semantic foundation for modeling system requirements, behavior, structure, and integration with a broad range of engineering analysis. SysML represents a subset of UML2 with extensions needed...

Formal Models of SysML Blocks

In this paper, we propose a formalisation of SysML blocks based on a state-rich process algebra that supports re nement, namely, CML. We rst establish a set of guidelines of usage of SysML block de nition and internal block diagrams. Next, we propose a formal semantics of SysML blocks described by diagrams that conform to our guidelines. The semantics is speci ed by inductive functions over the...
