Abstract: Attribute Based Access Control (ABAC) provides a high degree of security in access control mechanisms. Since ABAC is a fine-grained access control, it is being used wider in network security. In this paper, we have proposed an ABAC to emphasis access mechanism in pervasive computing for providing authorization to access resources which is in dynamic. The pervasive computing provides contextual information that is used as one of the attributes in ABAC to improve protection in a specific context. Moreover, ABAC is working based on the rich set of attributes to make an authorization decision more effective. To improve more on secured access privilege of users, the trust is included as one of the attributes in a subject that, provides access control in the dynamic environment. Due to the inclusion of trust, it provides flexibility and scalability in enforcing security policy. To provide access privilege to the user in a time-critical situation the trust value is calculated.
