GEZEL Hardware/Software Codesign GEZEL Hardware/Software Codesign Environment: GEZEL is a cycle-based hardware description language based on the Finite-State-Machine + Datapath (FSMD) model. The GEZEL tools offer stand-alone simulation, cosimulation, and code-generation into synthesizable (VHDL) code. Through user-defined library-block extensions in C++, new cosimulation interfaces can be added. GEZEL is open-source.
HW/SW Codesign with DE2i-150 Hardware/Software Codesign with DE2i-150: We are integrating the DE2i-150 board in the computer engineering curriculum as part of the ECE 4530 course, "Hardware/Software Codesign". The project website collects design examples and instructional materials. This project is supported by the Intel Embedded University Program.
GEZEL Hardware/Software Codesign Performance Evaluation of SHA-3 Candidates: The work of performance evaluation of SHA-3 candidates in ASIC and FPGA is part of the NIST sponsored project, "Environment for Fair and Comprehensive Performance Evaluation of Cryptographic Hardware and Software". This webpage list all the publications, source codes and scripts related to the SHA-3 hardware benchmarking work completed at Virgnia Tech.
Physical Unclonable Functions at SES Physical Unclonable Functions at SES: We are focusing on a comprehensive approach to build an efficient, practically usable PUF. We work in architecture design as well as high level algorithmic/statistical techniques. We have collected on-chip variability data of nearly 200 state-of-the-art ICs, designed functional prototypes of PUFs, analyzed aging effects, and created improved entropy extraction methods.
Environment for Implementation Attack Evaluation IA-Meter: Toolkit for Implementation Attack Evaluation: We're developing a modular testing environment for use in verifying the implementation attack resistance of secure systems. The proposed environment is an open-source solution for implementation attack testing, independent of the system platform. We aim to support the development of an implementation attack security standard in which standard test procedures are published openly and used to evaluate cryptographic systems.
ECDLP for Bluespec Open-source ECDLP Cryptanalytic Engine in Bluespec: We developed a hardware solver for the Elliptic Curve Discrete Logarithm (ECDLP) problem in Bluespec, for the curve secp112r1. This implementation has been demonstrated on a Nallatech FSB-Compute platform with Virtex-5 LX-330 FPGA. The measured performance of the resulting design is 114 cycles per Pollard rho step at 100 MHz, which gives 878 K iterations per second per ECC core.
Sensornet Unified Analyzer for Hardware and Software in Networked Environments SUNSHINE: A Software-Hardware Emulator for Sensor Networks: SUNSHINE (Sensor Unified aNalyzer for Software and Hardware in Networked Environments) supports hardware-software co-design in sensornets. By the integration of a network simulator TOSSIM, an instruction-set simulator SimulAVR, and a hardware simulator GEZEL, SUNSHINE can simulate the impact of various hardware designs on sensornets at cycle-level accuracy. The performance of software network protocols and applications under realistic hardware constraints and network settings can be captured by SUNSHINE.
