METHOD FOR UE PARAMETER UPDATE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18411469 titled 'METHOD FOR UE PARAMETER UPDATE
The abstract describes an apparatus that obtains a subscription permanent identifier and a root session key in a primary authentication process. It then generates an Authentication and Key Management for Applications (AKMA) key based on the root session key and generates a temporary identifier for the AKMA key using routing indicator values from a Unified Data Management (UDM) function. The apparatus can update the temporary identifier for the AKMA key based on a second routing indicator value without re-registering, but if needed, it can re-register the temporary identifier using the subscription permanent identifier and the second routing indicator value.
- Obtains a subscription permanent identifier and a root session key
- Generates an AKMA key based on the root session key
- Creates a temporary identifier for the AKMA key using routing indicator values from a UDM function
- Updates the temporary identifier based on a second routing indicator value without re-registering
- Can re-register the temporary identifier using the subscription permanent identifier and the second routing indicator value
Potential Applications: - Secure authentication processes - Key management for applications - Data encryption and security systems
Problems Solved: - Simplifying the process of updating temporary identifiers for keys - Enhancing security in authentication and key management systems
Benefits: - Improved efficiency in managing keys - Enhanced security measures for data protection - Streamlined authentication processes
Commercial Applications: Title: Secure Key Management System for Enhanced Authentication This technology can be utilized in industries such as finance, healthcare, and telecommunications to ensure secure access to sensitive data and information. It can also be integrated into IoT devices for enhanced security measures.
Questions about the technology: 1. How does this technology improve key management processes? 2. What are the potential risks associated with using temporary identifiers for keys in authentication systems?
Original Abstract Submitted
An apparatus comprising means for obtaining a subscription permanent identifier for said apparatus in a primary authentication process; means for obtaining a root session key; means for generating an Authentication and Key Management for Applications (AKMA) key based on said root session key; means for generating a temporary identifier for the AKMA key at least partly based on a first routing indicator value obtained from a Unified Data Management (UDM) function; means for initiating, in response to receiving a request from the UDM function to update the temporary identifier for the AKMA key using a second routing indicator value without a request to re-register the temporary identifier for the AKMA key updated based on the second routing indicator value, a re-registration process of the temporary identifier for the AKMA key using at least said subscription permanent identifier and the second routing indicator value.
