KM APPARATUS, QKD SYSTEM, KEY MANAGEMENT START CONTROL METHOD, AND COMPUTER PROGRAM PRODUCT - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240039710 titled 'KM APPARATUS, QKD SYSTEM, KEY MANAGEMENT START CONTROL METHOD, AND COMPUTER PROGRAM PRODUCT

Simplified Explanation

The abstract of the patent application describes a key manager (KM) apparatus that performs authentication processes with an opposing KM apparatus and a quantum key distribution (QKD) apparatus. The KM apparatus enables a KM function when both the inter-KM-apparatus connection authentication and the KM-QKD connection authentication are successful.

  • The KM apparatus includes one or more hardware processors.
  • The processors perform inter-KM-apparatus connection authentication indicating authentication processing with an opposing KM apparatus.
  • The processors also perform KM-QKD connection authentication indicating authentication processing with an opposing QKD apparatus.
  • The KM function is enabled only if both authentication processes are successful.

Potential Applications:

  • Secure communication systems: The KM apparatus can be used in secure communication systems to authenticate connections between KM and QKD apparatus, ensuring secure key distribution.
  • Quantum cryptography: The KM-QKD connection authentication process can be used in quantum cryptography systems to establish secure communication channels.

Problems Solved:

  • Authentication of connections: The KM apparatus solves the problem of authenticating connections between KM and QKD apparatus, ensuring secure key distribution.
  • Security in key management: By performing authentication processes, the KM apparatus enhances the security of key management systems.

Benefits:

  • Enhanced security: The KM apparatus ensures that only authenticated connections are established, reducing the risk of unauthorized access to keys.
  • Efficient key management: By enabling the KM function only after successful authentication, the apparatus optimizes key management processes.
  • Reliable communication: The authentication processes ensure reliable communication channels, enhancing the overall reliability of the system.


Original Abstract Submitted

according to an embodiment, a key manager (km) apparatus includes one or more hardware processors configured to: perform inter-km-apparatus connection authentication indicating authentication processing with an opposing km apparatus, and km-quantum key distribution (qkd) connection authentication indicating authentication processing with an opposing qkd apparatus; and enable a km function in a case where the inter-km-apparatus connection authentication is successful and the km-qkd connection authentication is successful.
