"Cryptographers Discover a New Foundation for Quantum Secrecy"

Researchers have proven the possibility of secure quantum encryption. Computer tasks such as sending private messages rely on encryption to protect user data. That encryption must withstand attacks from codebreakers with their own computers. Therefore, modern encryption methods rely on assumptions about mathematical problems that are hard for computers to solve. In the 1980s, cryptographers set mathematical foundations for this information security approach, but some researchers discovered that computational hardness was not the only way to protect secrets. Quantum theory is strongly connected to information and cryptography. This article continues to discuss cryptographers' discovery of a new foundation for quantum secrecy.
