ABSTRACT

While mobile computing provides a potentially vast business opportunity for many industry participants, it also raises issues such as security and performance. This paper proposes a Local Broker enabled MobiPass architecture based on our previous research outcomes. Our MobiPass architecture can convert the unpredictable and highly dynamic mobile environment into a trusted business platform. By setting customised rules against a MobiPolicy, the Mobipass architecture enables fine grained access control without necessarily having a prior knowledge or interaction with other encountered parties and environments. This paper extends our MobiPass architecture by introducing an additional element -- the Local Broker, to enhance the architecture's performance and efficiency. A detailed case study has been provided to explain the role that the Local Broker takes in the architecture.
