Trusted Software Architecture Evolution Based on Graph Transformation Rule

In current software architecture evolution community, Trusted attributes of component are less considered; and the concept of trusted software architecture evolution has not generally agreed. Focused on above shortages, This paper propose the idea of trusted software architecture evolution, it helps to increase the trustworthiness of evolution; on the basis of graph transformation rule, establish some basic evolution rules, Evolution operations are implemented according to these evolution rules. It can ensure the exactness of evolution process. The paper also introduce E-R diagram to represent trusted software architecture evolution; and finally through an evolution case, exactly and visually describes the sophisticated evolution process of trusted software architecture evolution.
