Key Exchange in the Quantum Era: Evaluating a Hybrid System of
Public-Key Cryptography and Physical-Layer Security
Today's information society relies on cryptography to achieve security goals such as confidentiality, integrity, authentication, and non-repudiation for digital communications. Here, public-key cryptosystems play a pivotal role to share encryption keys and create digital signatures. However, quantum computers threaten the security of traditional public-key cryptosystems as they can tame computational …
