1. Current security statusMarked in red are changes in current contributionPKMv1 – no changes in current contributionPKMv2Two/three options:RSA (RSA/ECC)Between the BS and SS. No need for backbone networkOptional mutual authenticationEAP based: EAP-TLS or EAP-SIMWith authentication server Mutual authenticationTLS v1.3 authentication for DPPBetween to SS. No need for backbone networkSupported cryptographic functions:RSA, ECC, DES, 3-DES, AES 128, AES-256, CMAC, HMAC, SHA-1, SHA-2, SHA-3
2. Authentication change suggestionRemove PKMv1Remove PKMv2 RSA (or RSA/ECC)TLS v1.3 can be used when backbone network is not availableRemove EAP-SIM?Security capabilities negotiation:Remove from registration (SBC-REQ), use the TLS capabilities negotiationRemove functions that are not NIST approved: DES, short RSA, SHA-1, CMAC (CMAC is approved but not recommended)
