"Reimagining Cryptography in a Post-Quantum World"

Researchers at the University of Maryland (UMD), with support from the National Science Foundation (NSF), are developing a framework for cryptographic systems that can withstand increasingly powerful quantum computers. In addition, they are working on changing how cryptography is taught, developed, and practiced. Jonathan Katz, a computer science professor, explained that the study's goal is to contribute to developing the foundational theory of cryptography in a post-quantum future. He emphasized that many aspects of classical cryptography will be different in a world where everyone has access to quantum computers, including honest parties and attackers. Therefore, the researchers will explore cryptosystem constructions that can be demonstrated to be secure against quantum computers. Initial emphasis will be placed on the private-key setting. Current public-key cryptosystems are known to be at risk due to quantum computers, but the security of private-key systems against such computers is less well understood. This article continues to discuss UMD researchers' work to develop a framework for cryptographic systems that can weather increasingly powerful quantum computers.
