Question: What is included in the N32-f security context to verify received messages that have undergone IPX modifications?
Option 1: Modification policy IDs, counters, and IVs
Option 2: Session keys, negotiated cipher suites, and data type encryption policy IDs
Option 3: List of security information of the IPX providers connected to the SEPPs (IPX security information list) and IPX provider identifier
Option 4: Raw public keys or certificates for that IPX
Explanation: The N32-f security context includes modification policy IDs, counters, and IVs to verify received messages that have undergone IPX modifications. This is necessary to ensure the integrity and authenticity of the messages. Modification policy IDs identify the policies used for modifications, while counters provide replay protection. IVs are used in conjunction with the negotiated cipher suites to encrypt and decrypt data.
