Overview of Quantum Key Distribution Technique within IPsec Architecture
This work addresses the problem of enhancing security in IP networks for users by integrating QKD with IPsec, but it is incremental as it reviews existing approaches without introducing new methods.
The paper provides an overview of existing solutions for integrating Quantum Key Distribution (QKD) into the IPsec architecture to establish secure communications in IP networks, aiming to guide future standardized designs.
Quantum Key Distribution (QKD) is an approach for establishing symmetrical binary keys between distant users in an information-theoretically secure way. In this paper we provide an overview of existing solutions that integrate QKD within the most popular architecture for establishing secure communications in modern IP (Internet Protocol) networks - IPsec (Internet Protocol security). The provided overview can be used to further design the integration of QKD within the IPsec architecture striving for a standardized solution.
