AEGIS-Based Efficient Solution for Secure Reconfiguration of FPGAs
Résumé
The reconfiguration of FPGAs includes downloading the bit- stream file which contains the new design on the FPGA. The option to reconfigure FPGAs dynamically opens up the threat of stealing the Intellectual Property (IP) of the de- sign. Since the configuration is usually stored in external memory, this can be easily tapped and read out by an eaves- dropper. This work presents a low cost solution in order to secure the reconfiguration of FPGAs. The proposed solution is based on an efficient-compact hardware implementation for AEGIS which is considered one of the candidates to the competition of CAESAR 1. The proposed architecture de- pends on using 1/4 AES-round for reducing the consumed area. We evaluated the presented design using 90 and 65 nm technologies. Our comparison to existing AES-based schemes reveals that the proposed design is better in terms of the hardware performance (Thr./mm2).
