Formulating Heterogeneous Access Control model for MANET Emergency Services

Abstract

Mobile ad hoc networks (MANETs) foster a new research trend in today’s computing. MANET unique features such as scalability, fault tolerant and autonomous system enable a network to be setup with or without any trusted authority makes it suitable for the emergency and rescue operations. During an emergency situation, there is a need for the information sharing among the group of rescuers. However, there is data collected during emergency which cannot be shared to all groups or within members in the same group. Thus, the privacy of data becomes a main concern here. We proposed a heterogeneous access control model which assigned an access to information during emergency based on information sensitivity and member-role in the group created at the emergency area. We formulate a complete HACM model with authentication and authorization. A privacy policy access policy is created and simple analysis with proving technique is used to evaluate it
