Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a network node may receive at least one communication of a plurality of communications associated with at least one physical layer channel, wherein a first set of the plurality of communications includes the at least one communication and is secured by a first security key, and a second set of the plurality of communications is secured by a second security key. The network node may decrypt the at least one communication based at least in part on the first security key, wherein the first security key is based at least in part on a first set of physical layer parameter values and the second security key is based at least in part on a second set of physical layer parameter values. Numerous other aspects are described.

Abstract: Disclosed are a communication system. All nodes in the communication system belong to a same layer 2 network. Well-known information of the layer 2 network can be obtained by the node. The node obtains the well-known information and forms a well-known key based on the well-known information and a preset key derivation algorithm; obtains a local MAC address of a first node and forms a first random number; forms first plaintext data based on the local MAC address and the first random number; and encrypts the first plaintext data based on the well-known key and a symmetric encryption algorithm, to form a first network layer address. Each node forms the well-known key based on the well-known information and the key derivation algorithm, and forms the network layer address based on the well-known key, the local MAC address, and the symmetric encryption algorithm.

Abstract: There is provided a method for managing a cluster of worker nodes that are controllable by a master node. The method is performed by an entity. A wireless device is automatically allowed to join the cluster as a worker node if the wireless device is authorised to join the cluster. The wireless device is authorised to join the cluster if the wireless device is registered to an owner of the master node and/or cluster of worker nodes. The worker nodes are responsible for providing a computational resource in a network.

Abstract: Provided are techniques for providing security for edge computing using location data. A command base location of an entity, an application identifier of the entity, and an expire date for the application identifier are determined. A message generated from the command base location and the application identifier is sent to a location authority. A signed command base location is received based on the command base location being within a jurisdiction of the location authority and a current date being before the expire date. A common key for the command base location is generated using the application identifier and the signed command base location. A public key is generated using the common key. A message is encrypted using the public key to create a cryptographic message. The cryptographic message is sent.

Abstract: An object is to provide a key generation method capable of maintaining a high security level in each of sliced networks when network slicing is applied to a core network. A key generation method according to this disclosure specifies network slice identification information indicating a network slice system that provides a service to be used by a communication terminal (50) among a plurality of network slice systems included in a core network (10) and, using the network slice identification information, generates a service key to be used for security processing in the network slice system indicated by the network slice identification information.
