ICEPOLE and CERG Support of CAESAR

SHARCS 2012

CERG is deeply involved in CAESAR: Competition for Authenticated Encryption: Security, Applicability, and Robustness. Two current (Ice and Dr. Gaj) and one former member of CERG (Marcin) are co-authors of ICEPOLE, a high-speed, hardware-oriented CAESAR candidate, suitable for any environment where specialized hardware (such as FPGAs or ASICs) can be used to provide high data processing rates. The paper about ICEPOLE has been presented at CHES 2014 in September 2014. In July 2015, ICEPOLE advanced to the second round of the CAESAR competition, and in September 2015, its tweaked version was presented at DIAC 2015 in Singapore. Independently, members of CERG developed a new hardware API for authenticated ciphers, which can be used in any future hardware implementations of all CAESAR candidates, presented for the first time at CryptArchi 2015. The specification of the GMU API is accompanied by a substantial number of supporting materials (a universal testbench, a script to generate test vectors, the PreProcessor and PostProcessor source codes, VHDL wrappers, etc.), simplifying the development and benchmarking of high-speed implementations of CAESAR candidates. Additionally, CERG supports an interactive, on-line database of FPGA results for CAESAR candidates and current authenticated encryption standards. Multiple high-speed and low-area implementations of CAESAR candidates are currently developed and benchmarked by members of CERG using both traditional and novel design methodologies. (8/17/15)

Welcome to the webpage of the Cryptographic Engineering Research Group at George Mason University. Cryptography, from Greek krpto (hidden) and grapho (write), is the science and practice of hiding information. Most Internet users come in contact with cryptography when they go to a secure website of an Internet retailer. Other popular applications are secure e-mail, Internet banking, mobile phones, etc. Cryptography has its roots in mathematics, computer science and engineering. Cryptographic Engineering is concerned with all aspects of implementing cryptographic algorithms in hardware and / or software. This ranges from high performance implementations to ultra-low power implementations of public key and secret key algorithms, fault tolerant implementations, attack resistant implementation and even implementations of attacks.

Sources of Randomness in Digital Devices and Their Testability

Dr. Viktor Fischer, Hubert Curien Laboratory, Jean Monnet University, Saint-Etienne, France
Date: Wednesday, May 4th, 10:30 AM - 11:30 AM
Location: Engineering Building, Room 4801

Digital electronic devices are often used to implement data security systems-on-chip (SoC), like smart cards. Random bit stream generators constitute one of the main building blocks of such systems. They use some uncontrollable physical analog phenomenon as a source of randomness. The random variations in this analog process must be converted to a digital bitstream using some intrinsic analog to digital conversion or some extrinsic digitization technique. This conversion should be feasible using purely digital technology, because the use of some analog electronic blocks inside the device would increase the total cost of the system.

Benchmarking of Round 2 CAESAR Candidates

The CERG Team announced the results of hardware benchmarking of Round 2 CAESAR Candidates on July 25, 2016. The benchmarking effort involved over 40 distinct submission packages covering 28 candidate families, submitted by 13 groups from all over the world. About 20 implementations have been developed by members of CERG. All implementations have been benchmarked using four high-performance FPGA families: Virtex 6, Virtex 7, Stratix IV, and Stratix V. Additionally, implementations of 10 lightweight algorithms have been benchmarked using four low-cost FPGA families: Spartan 6, Artix 7, Cyclone IV, and Cyclone V. The comprehensive rankings can be reviewed by accessing the ATHENa Database of Results. Additionally, two web-based tables, describing, respectively all submission packages and all variant-architecture pairs, are available at the ATHENa Website. Majority of the designs submitted for benchmarking are compliant with the CAESAR Hardware API, developed by members of CERG, and approved by the CAESAR Committee. (07/25/2016)
