Researchers create key technology for quantum cryptography commercialization

In modern cryptosystems, users generate public and private keys that guarantee security based on computational complexity and use them to encrypt and decrypt information. Recently however, modern public-key cryptosystems have faced potential security loopholes against quantum computers with great computational power. As a solution, quantum cryptosystems have been highly noticed. They use quantum keys that guarantee security based on quantum physics rather than computational complexity; thus, they are secure even against quantum computers. Therefore, quantum cryptosystems are expected to replace …
