Software Radio terminals being able to reconfigure to various radio access systems, will require robust security mechanism to protect the mobile terminals from unauthorized access and to ensure the integrity of internal process involved in reconfiguration when exchanging information with the network. This paper aims to propose an energy efficient reconfigurable hardware architecture which supports data integrity for the secured downloading of software in reconfigurable receivers. Improved
