Post-Quantum Cryptography in Hardware and Embedded Systems
Major investments by national governments and high-tech companies have led to first demonstrations of quantum supremacy, i.e., computations conducted by a quantum computer that no classical computer can perform in any feasible amount of time. The goal of this project is to support NIST in its effort to develop a new generation of public-key cryptographic standards, resistant against quantum computers, a.k.a. NIST Post-Quantum Cryptography (PQC) Standardization Process. In Rounds 1 and 2 of this effort, the assessment of PQC candidates has focused primarily on their security and software efficiency. Our aim is to set the foundation for the early, systematic, and comprehensive study of the hardware and embedded system efficiency of the most promising PQC candidates. The next 5-10 years are very likely to bring the biggest revolution in cryptography, since the invention of public-key cryptography in mid-1970s. This project gives us a unique opportunity to influence the choice of future cryptographic standards, which are likely to be developed and deployed within the next decade and remain in use for the significant portion (if not the rest) of the 21st century.
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.
