Real parameters: cipher algorithms, key lengths, SCAS test cases

5G Security Parameters

NR encryption algorithms: NEA0 (null, for emergency calls), NEA1 (SNOW 128-EEA1, 128-bit), NEA2 (AES-128-CTR, 128-bit), NEA3 (ZUC-128-EEA3, 128-bit). Integrity algorithms: NIA1 (SNOW 128-EIA1), NIA2 (AES-128-CMAC), NIA3 (ZUC-128-EIA3). SUCI concealment uses Profile A (ECIES with Curve25519) or Profile B (ECIES with secp256r1). TLS 1.3 cipher suites for SBI: TLS_AES_128_GCM_SHA256 and TLS_AES_256_GCM_SHA384. IPsec for N2/N3 typically uses AES-256-GCM with IKEv2. Key refresh for KgNB occurs at handover or through intra-cell key update.
