APPARATUS AND METHOD FOR COMMUNICATION ESTABLISHMENT IN AUTHENTICATION AND KEY MANAGEMENT FOR APPLICATIONS (AKMA) - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240292212 titled 'APPARATUS AND METHOD FOR COMMUNICATION ESTABLISHMENT IN AUTHENTICATION AND KEY MANAGEMENT FOR APPLICATIONS (AKMA)

The disclosure pertains to a 5G or 6G communication system designed to support higher data transmission rates. The embodiments presented introduce a system and method for key refresh in Authentication and Key Management for Applications (AKMA). The proposed method involves requesting refreshing parameters from the network when the Key Identifier Set (KIS) is about to expire. Additionally, the method addresses key synchronization issues at the User Equipment (UE) side, Application Function (AF) side, and Access and Mobility Management Function (AANF) using a key index included as part of the AKMA Key Identifier (A-KID). The method also provides mechanisms to deliver the refresh parameter to the Authentication Server Function (AUSF), AANF, and UE as part of the AKMA refresh procedure or User Plane Update (UPU) procedure. Furthermore, the method supports AKMA key refresh with minimal impacts on AKMA services in a 5G system.

  • Supports key refresh in AKMA by requesting refreshing parameters before the KIS expires.
  • Addresses key synchronization issues at UE, AF, and AANF using a key index in A-KID.
  • Delivers refresh parameters to AUSF, AANF, and UE as part of AKMA refresh or UPU procedure.
  • Minimizes impacts on AKMA services during key refresh in a 5G system.
    • Potential Applications:**

- Telecommunications industry for enhanced data transmission rates. - Network security for improved authentication and key management. - IoT devices for secure communication protocols.

    • Problems Solved:**

- Key refresh process optimization. - Key synchronization issues at different network elements. - Minimizing disruptions during key refresh in a 5G system.

    • Benefits:**

- Enhanced security in communication networks. - Efficient key management for applications. - Seamless key refresh process with minimal service impacts.

    • Commercial Applications:**

Title: Enhanced Key Management System for Communication Networks This technology can be utilized in telecommunications companies to improve data transmission rates and enhance network security. It can also be integrated into IoT devices for secure communication protocols, ensuring data privacy and integrity. The market implications include increased efficiency in key management processes, leading to improved network performance and customer satisfaction.

    • Questions about Key Refresh in AKMA:**

1. How does the proposed method address key synchronization issues in a 5G system? 2. What are the potential applications of this technology beyond telecommunications networks?


Original Abstract Submitted

the disclosure relates to a 5g or 6g communication system for supporting a higher data transmission rate. embodiments herein provide a system and method for key refresh in authentication and key management for applications (akma). the proposed method is to support krefresh by requesting the refreshing parameters from the network once the kis about to expire. further, the proposed method is to support krefresh by requesting the refreshing parameters from the network once the kis about to expire. further, the proposed method is used to support a mechanism to address the key synchronisation issue at a user equipment (ue) side, an application function (af) side and at an aanf using a key index included as a part of akma key identifier (a-kid). further the proposed method uses certain mechanisms to provide the refresh parameter to the ausf, the aanf and the ue as a part of akma refresh procedure or as a part of upu procedure. further, the proposed method supports akma key refresh with limited impacts on akma services in 5g system.
