Developing cryptographic algorithms that remain secure against the potential capabilities of quantum computers.
Post-Quantum Cryptography is a research area focused on designing and analyzing cryptographic systems that can resist attacks from quantum computers. Traditional public-key cryptographic schemes, such as RSA and ECC, are vulnerable to quantum algorithms like Shor’s algorithm, which can break their security assumptions. This topic explores alternative approaches based on hard mathematical problems that are believed to be resistant to quantum attacks, such as lattice-based, hash-based, and code-based cryptography. Research also addresses practical concerns including performance, implementation security, and standards development. As quantum computing advances, post-quantum cryptography plays a critical role in ensuring long-term confidentiality, digital trust, and the future resilience of secure communication systems.
