full_form: Long term Key
context: Figure 9.6.2.1: LTK Generation Process The high-level steps involved in the LTK generation process are described below: Step 0: Operator makes a decision based either on the policy or detected LTK compromise to update LTK. Steps 1-8 describe the LTK Re-generation process. Step 1: On detection of the compromise, or triggering of the LTK re-generation according to policy, the UE / eSIM and the AUSF / ARPF perform a mutual authentication and establish a secure connection. NOTE 1: Mutual authentication between the UE / eSIM and the AUSF / ARPF may be performed by leveraging existing trust between SM-DP / SM-SR and MNO / AUSF / ARP e.g., using eSIM private key. Details of mutual authentication and key agreement between eSIM/UE and AUSF/ARPF/SM-DP are specified in GSMA SGP.02 [11] and GSMA SGP.01 [17]. Step 2: The UE / eSIM or the AUSF / ARPF notifies one another of the compromise (or of any other policy-based triggering of the LTK re-generation) over the secure connection established in
description: Long Term Key (LTK) is a critical network attribute used for securing connections and authenticating entities within the telecommunications network. It plays a vital role in ensuring the integrity and confidentiality of data exchanged between different network components.
explanation: The description emphasizes LTK's function in authentication, secure connection establishment, and compromise detection, classifying it as a security parameter crucial for network protection.
