A method according to some embodiments include reporting, by a beamformee, an encryption capability indicator to a beamformer, wherein the encryption capability indicator is indicative of a capability of the beamformee to encrypt a feedback frame. The method may also include receiving, by the beamformee from the beamformer, an announcement frame in response to the beamformer receiving an indication that the beamformee is capable of encrypting the feedback frame, and then sending, by the beamformee, an encrypted feedback frame.

A method (200) for operating a User Equipment (UE) is disclosed, the UE configured to connect to a communication network. The method comprises: indicating to the communication network an Integrity Protection for User Plane (IPUP) mode supported by the UE when requesting registration with the communication network (202). The IPUP mode comprises one of: use of Integrity Protection for User Plane data exchanged with the UE (202a), non-use of Integrity Protection for User Plane data exchanged with the UE (202b), or use of Integrity Protection for User Plane data, and non-use of Confidentiality Protection for User Plane data (202c). Also disclosed are an apparatus for operating a UE, methods and apparatus for operating a radio access node and a core node of a communication network, and a computer program operable to carry out methods for operating a UE, a radio access node and/or a core node of a communication network.

Techniques and architectures enable a wireless communications system to receive and transmit a message for which a user of a mobile device has specified to be delivered on a particular date and time to a contact in an address book of the user. Further, the network securely stores the message by encrypting the message with a strength of encryption that is based on the length of time that the message will be stored before its scheduled delivery.

In accordance with one or more embodiments described herein, a method is provided. The method includes receiving a request to assume control of a vehicle generated by a candidate operator via a first communication pathway. The method obtains a key from an onboard controller of the vehicle and communicates the key to the candidate operator via a second communication pathway that is different from the first communication pathway. The method determines the candidate operator to be a confirmed operator based at least in part on obtaining the key from the candidate operator via the first communication pathway.
