摘要: With the increased interest in Web services composition, more and enterprises businesses depend on this paradigm. Open, distributed dynamic properties of schema, there is a pressing need for secure daily transactions. Orchestration choreography language provide basic standards interaction, collaboration, negotiation among services, but they are not give any manners or operation styles specifications. Despite such security mechanisms, formal module them still lacking. For giving general guide to implement orchestration language, we approach carry out those goals. To target, emphasize by designing an extension Spi calculus with Secure Global Calculus. The precisely identifies each principal from local viewpoint. global describes interaction scenario vantage point view. We called our method SpiG4WSC calculus. believe that combination strong practical needs composition theoretical foundations will lead bridge between practice theories. contribution paper (1) syntax semantic calculus; (2)applying model presenting orchestration, emphasizing basis services; (3)describing choreography, frame processes.
