A system, apparatus and method are provided for supporting shared sessions in communication networks. The system, apparatus and method include interoperation between a User Equipment and serving nodes of a communication network. The serving nodes communicate with at least one anchor node of the communication network. In some implementations a shared session identifier and User Equipment identifying component are used to identify a User Equipment within a shared session. In some implementations, a paging notification is used to inform one or more target User Equipment that of a downlink message relating to the shared session.

The present disclosure relates to a method, apparatus, and computer program for setting an encryption key in a wireless communication system; and a recording medium for same. According to one embodiment of the present disclosure, a method for setting an encryption key size in a wireless communication system may comprise: a step in which a first controller of a first device receives a first message containing information on a minimum value of a first encryption key size from a first host of the first device; and a step in which the first controller transmits, to the first host, a second message indicating an encryption change. The second message may contain information on the first encryption key size.

A computer implemented method of a network access point for secure network access by a mobile computing device, the mobile device being associated with the access point by a digitally signed record in a blockchain wherein the blockchain is accessible via a network and includes a plurality of records validated by miner computing components, the method including receiving a request from another network access point to associate the mobile device with the other access point, the request having associated identification information for the mobile device; responsive to a verification of an entitlement of the mobile device to access the network, generating a new record for storage in the blockchain, the new record associating the mobile device with the other access point and being validated by the miner components such that the other access point provides access to the network for the mobile device based on the validation of the new record.

An encrypted sequence that includes an authentication key may be received. A base key stored at a device may be identified and the encrypted sequence may be decrypted with the base key to obtain the authentication key. A challenge value may be received and the authentication key may be combined with the challenge value to generate a device ephemeral key. An authentication result may be generated for the device based on a combination of the device ephemeral key and the challenge value. Furthermore, the authentication result may be transmitted to a mobile network to authenticate the device.

Systems, methods, and devices are described herein for executing a lockdown of electronic locks deployed in a local network of interconnected devices. In example implementations, each electronic lock is provided with a unique encryption key specific to that electronic lock and is provided with a shared encryption key. To execute a lockdown of all electronic locks in the local network, a server generates a locking instruction and encrypts it using the shared encryption key. The server then transmits the encrypted locking instruction to the gateway devices of the local network which, in turn, transmit it to each of the electronic locks. Upon receipt of the encrypted locking instruction, the electronic locks attempt to decrypt it using the shared encryption key. Upon successful decryption of the encrypted locking instruction, an electronic lock toggles to a lock state.

A key-based interleaver for enhancement the security of wireless communication includes a physical layer communication channel key to provide security even when the software encryption key is compromised. A method of creating a secure communication link using a physical layer interleaving system includes implementing a key policy implementation that utilizes temporal dependency and interleaving bits using a flexible inter and intra-block data interleaver.

A User Equipment (UE) including a wireless transceiver and a controller is provided. The wireless transceiver performs wireless transmission and reception. The controller selects a PLMN via the wireless transceiver, and determines whether a predetermined ciphering algorithm is adopted for a Non-Access Stratum (NAS) security context. In response to selecting the PLMN and the predetermined ciphering algorithm being adopted for the NAS security context, the controller sends an initial NAS message in which Information Elements (IEs) are in cleartext only to the selected PLMN via the wireless transceiver.

Techniques disclosed herein relate to the pairing of a pairing initiator device and a pairing responder device for communication. The pairing initiator device and the pairing responder device range with each other to determine the distance between the pairing initiator device and the pairing responder device. Based on the distance being below a threshold distance, the pairing initiator device and the pairing responder device wirelessly pair with each other without further input from the user.

An operation method of a user device which performs near field communication (NFC) with a card reader includes downloading a service certification of a service, which the card reader provides, from a service authentication server through a network, sending status information of the user device to the card reader, receiving a service identifier (ID) which the card reader sends depending on the status information, performing an authentication process with the card reader based on a symmetric key when the service ID is present in the downloaded service certification, and sending an authentication success message to the card reader when the authentication process succeeds.

A system and method for encrypting a data frame of a low-power communication protocol. The method includes providing an input data frame, the input date frame includes a random number, a unique identifier, and a payload data, encrypting the payload data, generating a Message Integrity Code (MIC), generating a rotating identifier by encrypting the unique identifier, and generating an output frame based on the generated rotating identifier, the generated MIC, and the encrypted payload data.
