Abstract: A terminal device obtains M pieces of first downlink channel sub-data, where each piece of first downlink channel sub-data corresponds to one data space in M data spaces. For an ith piece of first downlink channel sub-data in the M pieces of first downlink channel sub-data, the terminal device determines, based on a first dictionary corresponding to an ith data space, first information corresponding to the ith piece of first downlink channel sub-data, where M pieces of first information are determined in total. The terminal device sends first indication information, to indicate the M pieces of first information. Different data spaces can represent different channel environment information. The terminal device feeds back first information corresponding to different data spaces, so that an access network device can determine a correspondence between first information and environment information. Accuracy of the first information fed back by the terminal device is improved.

Abstract: Systems and methods are for confidentially and securely provisioning data to an authenticated user device. A user device may register an authentication public key with an authentication server. The authentication public key may be signed by an attestation private key maintained by the user device. Once the user device is registered, a provisioning server may send an authentication request message including a challenge to the user device. The user device may sign the challenge using an authentication private key corresponding to the registered authentication public key, and may return the signed challenge to the provisioning server. In response, the provisioning server may provide provisioning data to the user device. The registration, authentication, and provisioning process may use public key cryptography while maintaining confidentiality of the user device, the provisioning server, and then authentication server.
