the emergence of Web services technologies and the evolution of distributed systems toward Service Oriented
Architectures (SOA) have helped significantly promote collaboration and information sharing. Data exchange among
heterogeneous platforms and provision of service security are two notable challenges in SOA architecture that require
due consideration. Due to different security policies in inter-organizational environment, current information security
mechanisms and traditional access control models are often unable to satisfy users’ security requirements. Trust
negotiation is a cruicial and promising approach in trust establishment and secure interactions between entities for
which there is no pre-existing knowledge or experience. In this paper, a new access control model based on attributes
and trust negotioation techniques to overcome these challenges is proposed. This model is developed within XACML
standard architecture together with Xengine evaluation engine features. Numerical results and performance
evaluation of our model show that the proposed model has more flexibilility and performance than existing models.
Moreover, the model is able to provide service security and also, proves it’s applicability in real e-government and
e-commerce environments
