tl;dr Cryptographers are searching for encryption schemes that can withstand attacks from both classical and quantum computers, as the emergence of quantum computing poses a threat to current encryption methods. They have yet to find a problem that is provably hard for computers to solve. The National Institute of Standards and Technology (NIST) is working on post-quantum encryption algorithms, with CRYSTALS-Kyber being recommended for public use by 2024. This article discusses the history of encryption, the rise of quantum computing as a threat, and the challenges in finding quantum-resistant cryptographic schemes. It emphasizes the need to strike a balance between mathematical complexity and practical implementation for data security in the future. Cryptographers continue to search for encryption methods that can resist both classical and quantum computer attacks, given the uncertainty in the future of data security.
