T (Normative) Security for edge computing |R17| p. 278
T.1 General p. 278
The 5G Edge computing service is described in TS 23.548. It defines the enhancements of 5G System to support Edge Computing.
T.2 Security of network exposure to edge application server p. 278
It is defined in clause 6.4 of TS 23.548 that the network could expose network information to the local AF with two scenarios, i.e.
- Case 1: L-PSA UPF may expose the network information to local AF via Local NEF, or
- Case 2: L-PSA UPF may expose the network information to local AF directly. However, How to deliver the information on N6 is out of scope.
T.3 Security of EAS discovery procedure via EASDF in non-roaming Scenario p. 278
Annex P of the present document should be followed, with the following additions, to protect the discovery messages between the UE and the EASDF which is used as the DNS server for EAS discovery in the non-roaming case. If the core network is used to configure the security information, the SMF is preconfigured with the EASDF security information (credentials to authenticate the EASDF, supported security mechanisms, port number, etc.) and provides the security information to the UE as follows:
The SMF provides the EASDF security information to the UE via PCO.
