Systems and methods for end to end encryption are provided. In example embodiments, a computer accesses an image including a geometric shape. The computer determines that the accessed image includes a candidate shape inside the geometric shape. The computer determines, using the candidate shape, an orientation of the geometric shape. The computer determines a public key of a communication partner device by decoding, based on the determined orientation, data encoded within the geometric shape. The computer receives a message. The computer verifies, based on the public key of the communication partner device, whether the message is from the communication partner device. The computer provides an output including the message and an indication of the communication partner device if the message is verified to be from the communication partner device. The computer provides an output indicating an error if the message is not verified to be from the communication partner device.

A privacy information transmission method, an apparatus, a computer device and a computer-readable medium are disclosed. The method may include: generating authentication information in response to receiving of an identity registration request message sent by a terminal device via a base station, and encrypting the authentication information with a first private key to generate encrypted authentication information; sending a first identity identification request message carrying the encrypted authentication information to the terminal device; and receiving an identity identification response message returned by the terminal device, and acquiring privacy information from the identity identification response message.

In some embodiments, a non-transitory computer readable medium is disclosed. In some embodiments, the medium includes instructions for providing a mobile user monitoring solution that, when executed by a processor, cause the processor to capture a first message transmitted over an N11 interface, extract at least one type of session ID and a first Next Generation Application Protocol (NGAP) tunnel endpoint identifier (TEID) from the first message, store the at least one type of session ID and the first NGAP TEID in a first N11 protocol data unit (PDU) session record, capture a second message transmitted over an N3 interface, extract a general packet radio service (GPRS) tunneling protocol (GTP)-user plane (U) TEID from the second message, wherein the GTP-U TEID matches the first NGAP TIED, and retrieve information associated with session details record using the GTP-U TEID.

The present disclosure relates to the technical field of communication security, and provides a data transmission method applicable to a control plane function entity, including: determining target user plane data which needs to be subjected to security protection between a target user equipment and a user plane function entity; and sending a notification message to a Radio Access Network function entity and the target user equipment, with the notification message configured to instruct that the security protection is performed on the target user plane data between the target user equipment and the user plane function entity. The present disclosure further provides a data transmission system, an electronic device, and a computer-readable storage medium.

Embodiments are disclosed for encrypting media access control (MAC) Header fields for Wireless LAN (WLAN) privacy enhancement. For example, a transceiver of a station (STA) or an access point (AP) can set a real time Media Access Control (MAC) header bit in a payload of an aggregated MAC Protocol Data Unit (A-MPDU) subframe to an actual value of a power management (PM) field of a MAC header of the A-MPDU subframe. The transceiver can encrypt the payload, set the PM field to an over the air (OTA) PM value, and transmit the A-MPDU subframe over the air. The OTA PM value can include all zeros, a predetermined value, or a randomized value The transceiver can also set static MAC header bits in the payload of the A-MPDU subframe to corresponding actual values of an aggregated MAC service data unit (A-MSDU) present field of the A-MPDU subframe.

A security protection method and an apparatus to implement security protection for a plurality of non-access stratum (NAS) connection links. The method includes determining, by a terminal, a first parameter, where the first parameter is used to indicate an access technology used to transmit a non-access stratum NAS message. The terminal can support at least two access technologies, and can separately maintain a corresponding NAS COUNT for each of the at least two access technologies. The method further includes performing, by the terminal, security protection on the NAS message based on the first parameter, a NAS key, and a NAS COUNT corresponding to an access technology used to transmit the NAS message. This application is applicable to a process of performing security protection on a NAS message.
