Abstract: A system for transmission data protection includes user equipment (UE) and an access point. The access point sends a broadcast message that carries a public key for encryption. The UE receives and stores the public key for encryption. The UE obtains a global public key or a private key corresponding to the UE, and protects transmission data using the public key for encryption and the global public key or the private key corresponding to the UE.

Abstract: A key distribution method is disclosed. In this method, a key request can be received by a key management system (KMS) from a mobile operator network element (MNO). The key request can carry a public key of UE. At least one PVT and one SSK can be allocated to the US based on an IBC ID. The at least one PVT and SSK can be encrypted based on the public key to generate ciphertext; and an object can be signed based on a preset digital signature private key (DSPK) to generate a digital signature. The object can include the public key and the ciphertext. Still, a signature validation public key associated with the DSPK can be determined and a key response can be returned to the MNO. The key response can carry the signature validation public key, the public key of the UE, the ciphertext, and the digital signature.
