A Low-Power and High Throughput Reconfigurable Data Integrity Unit for Software Radio

L. Thulasimani and M. Madheswaran

Abstract—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 SHA-1(SHA-192) algorithm and a reconfigurable hardware design to support different protocols, which uses MD5/SHA 192 algorithm for integrity unit, is proposed. The hash algorithms MD-5, SHA-1, and the unified architecture of MD-5and SHA-192 have been implemented using Verilog, and their hardware utilization on the FPGA device is being compared.

Index Terms—SDR, Reconfigurability, SHA-192, Unified architecture, Hardware utilization.
