Abstract: This paper studies the establishment and evaluation of Internetware system initialization and evolution for trust relationship among entities, establishes an Internetware system structure model by structure analysis, proposes an evolution evaluating model for dependability based on the Internetware system structure model, which uses hierarchical Petri nets. The model evaluates dependability evolution of Internetware from whole system architecture and internal access control policies of entities. The proposal solves the problem that trust measurement and evolution model of Internetware lacks support to the dependability of system initialization and newly created entities. Additionally, the proposal provides mechanism for server entities to establish trust to client entities.

Key words:  Internetware, dependability, evolution, evaluation, hierarchical Petri nets
