CERG Support of CAESAR


CERG is deeply involved in CAESAR: Competition for Authenticated Encryption: Security, Applicability, and Robustness. Members of CERG have developed the CAESAR Hardware API for authenticated ciphers, approved by the CAESAR Committee. Our group has also developed comprehensive Development Package, including VHDL and Python code common for all candidates, and the corresponding Implementer's Guide. CERG has contributed optimized high-speed RTL implementations for 24 Round 2 CAESAR Candidates and AES-GCM. Members of our team have also conducted comprehensive FPGA benchmarking of all Round 2 implementations, submitted by 14 hardware design teams from all over the world. The comprehensive rankings can be reviewed by accessing the ATHENa Database of Results. The summary of the Round 2 RTL benchmarking effort and an alternative benchmarking methodology based on High-Level Synthesis were presented at DIAC 2016. Additionally, two current members (Ice and Dr. Gaj) and one former member of CERG (Marcin) were co-authors of ICEPOLE, a high-speed, hardware-oriented Round 2 CAESAR candidate, suitable for any environment where specialized hardware (such as FPGAs or ASICs) could be used to provide high data processing rates.

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.


Public Key Cryptography Using Hardware/Software Codesign for the Internet of Things

Ahmad Salman, ECE PhD Defense
Date: Wednesday, August 2nd, 1:00 PM - 3:00 PM
Location: Engineering Building, Room 3507

Embedded electronic devices and sensors are playing a major role in bridging the gap between the physical world and the virtual world. Billions of devices such as smartphones, smart watches, wearables, medical implants, and Wireless Sensor Nodes (WSN) are considered building blocks in making "The Internet Of Things" (IoT) a reality.

Hardware-Software Codesign Approaches to Public Key Cryptosystems

Malik Umar Sharif, ECE PhD Defense
Date: Wednesday, August 2nd, 10:00 AM - 12:00 PM
Location: Engineering Building, Room 4801

If a quantum computer with a sufficient number of qubits was ever built, it would easily break all current American federal standards in the area of public-key cryptography, including algorithms protecting the majority of the Internet traffic, such as RSA, Elliptic Curve Cryptography (ECC), Digital Signature Algorithm (DSA), and Diffie-Hellman.
