Study on Security for Next Radio (NR) Integrated Access and Backhaul (IAB)
The present document:
- Describes potential security threats and vulnerabilities that are applicable to the enhanced IAB architecture specified in the TS 38.300 [3], TS 38.331 [8], TS 38.321 [9] and TS 38.340 [10].
- Identifies potential security requirements for those potential security threats and vulnerabilities.
- Proposes candidate solutions to ensure that the enhanced IAB architecture specified in the 3GPP TS 38.300 [3], TS 38.331 [8], TS 38.321 [9] and TS 38.340 [10] does not introduce security vulnerabilities in the 5G system providing a secure connection for the UEs connecting to the NR through IAB node(s).
- Concludes with the solutions that should be included in a future normative phase.
