At a glance

Version 20.2.0 puts an invalid point inside a concealed identifier, includes user equipment in de-concealment setup, and revises the fifth-generation local area network policy test.

What changed

Clause 4.2.1.2 of technical specification (TS) 33.514 tests rejection of concealed identifiers using elliptic curve integrated encryption scheme (ECIES) protection with invalid public keys. Under that protection scheme, the tester constructs a Profile B subscription concealed identifier (SUCI) for the provisioned subscription permanent identifier (SUPI). Its user equipment (UE) ephemeral public key in the protection scheme output is "an invalid elliptic curve point". Previously, the tester used an invalid point as a public key to encrypt the SUPI.

Clause 4.2.1.1 now lists the UE alongside the unified data management (UDM) product in its test environment. Previously, that environment listed the authentication server function (AUSF) and access and mobility management function (AMF), but not a UE. The updated procedure includes triggering authentication from the UE using the configured protection scheme. Both versions filter the "Nudm_UEAuthentication_Get Response message" sent from UDM to AUSF over N13, containing the SUPI. The step changes wording from shall filter to filters.

Clause 4.2.8.1 revises the fifth-generation local area network (5G LAN) user plane (UP) test for protocol data unit (PDU) sessions. The verification checks that "the UP security policy is the same for PDU sessions associated with the same 5G LAN group". Previously, the wording checked the same policy across all 5G LAN UEs. The current condition places SUPI1 and SUPI2 with UEs associated with the same group.

How this page was made

Written with AI assistance from two versions of the specification indexed by 3GPP Scout and the 3GPP CR database. An AI model (GPT-6 Sol) drafted each sentence and named the source it rests on. Code checked every quote word for word against the stored source text, and the live check fetched each TDoc again before publishing. A second AI model from another company (Claude Opus 5.5) reviewed the page against the same sources. The 3GPP documents themselves govern.
