A Practical Modelling Notation for Secure Distributed Computation

Mobile code computation has lead to a new paradigm of distributed computation. A mobile process can move from site to site and interact with the resources as a local process. To prevent the misuse resources, authentication and authorization need to be dealt with. Many modeling languages have been proposed to model distributed computation; Ambient Calculus [1] is one of them. Ambient Calculus, a type of process calculus, can be used to model boundary crossing activities in a mathematical notation. SJAN, a modeling language, extends the basic idea of Ambient Calculus, but it has a simple notation, design and representation. SJAN can be verified by J-Ambient, a JAVA implementation, to certify the correctness of the model. In this paper, we will introduce SJAN notation and JAmbient. SJAN can be also used to model grid computation and provides the security consideration. Thus, finally, we will address several security scenarios in SJAN to show its functionality.
