Cryptographic message authentication is a growing need for FPGA-based embedded systems. In this paper a customized FPGA implementation of a GHASH function that is used in AES-GCM, a widely-used message authentication protocol, is described. The implementation limits GHASH logic utilization by specializing the hardware implementation on a per-key basis. The implemented module can generate a 128bit...
Network Multimedia data often need to be encrypted to protect private content and access control. Considering performance constraints and embedded system issues, many hardware solutions are proposed to provide high security level and fast encryption process. However these hardware solutions are often unchangeable at run-time and cannot adapt to data-dependent encryption schemes. Reconfigurable architectures...
In this paper we propose a design methodology to explore partial and dynamic reconfiguration of modern FPGAs. We improve an UML based co-design methodology to allow dynamic properties in embedded systems. Our approach targets MPSoPC (Multiprocessor System on Programmable Chip) which allows area optimization through partial reconfiguration without performance penalty. In our case area reduction is...
