摘要： A method, device and system for providing user-centric connections to a location comprising digital collaboration tools, as well as software for carrying out the method. The method includes a network device having a beacon system for proximity detection and a BYOD (Bring Your Own Device). A confirmed BYOD proximity can be used to initiate the setup of a data channel between the network device and the BYOD, and further join the BYOD to a UC (Unified Communications systems and tools) session.

摘要： A method performed by a wireless device is provided. The method comprises identifying that an Access and Mobility Management Function (AMF) relocation procedure with re-route via a Radio Access Network (RAN) node is being performed for the wireless device and generating a key associated with a primary authentication of the wireless device. The method further comprises using the key for performing a Non Access Stratum Security Mode Control (NAS SMC) procedure with a first network node operating as a target AMF, and wherein the use of the key by the wireless node is restricted such that the wireless device is restricted from using the key for at least one procedure other than the NAS SMS procedure with the first network node operating as the target AMF.

摘要： A method for processing multi-source data includes: generating a private key fragment of the data providing node, as well as an encryption public key and an evaluation public key, in which, other participating nodes include other data providing nodes and a data using node; generating ciphertext data by encrypting local sample data with the encryption public key, and sending the ciphertext data to a coordination node for training a machine learning model; receiving ciphertext model parameters corresponding to model parameters of the machine learning model trained by the coordination node, in which, the ciphertext model parameters are determined by the coordination node based on the evaluation public key and the ciphertext data received; and decrypting the ciphertext model parameters with the private key fragment, and sending a decrypted model parameter fragment to the data using node

摘要： A method performed by a network server is provided for authentication and key management for a terminal device in a wireless communication network. The method includes authenticating the terminal device during a primary authentication session for the terminal device. The method further includes responsive to a successful authentication of the terminal device, obtaining a first key. The method further includes generating bootstrapping security parameters. The parameters include a second key derived from the first key and a temporary identifier. The temporary identifier identifies the terminal device and the bootstrapping security parameters.

摘要： A session request method, a session request apparatus, a terminal, and a storage medium are provided. The session request method includes: generating an authentication server key when a key agreement authentication is passed; determining, according to the authentication server key, a key identifier of an authentication and key management for applications (AKMA) anchor key; when the key identifier is invalid, updating the key identifier according to a mobile subscriber identification number (MSIN); and sending an updated key identifier to an application function, to request a key-based session.

摘要： Techniques for identity-based message integrity protection and verification between a user equipment (UE) and a wireless network entity, include use of signatures derived from identity-based keys. To protect against attacks from rogue network entities before activation of a security context with a network entity, the UE verifies integrity of messages by checking a signature using an identity-based public key PKID derived by the UE based on (i) an identity value (ID) of the network entity and (ii) a separate public key PKPKG of a private key generator (PKG) server. The network entity generates signatures for messages using an identity-based private key SKID obtained from the PKG server, which generates the identity-based private key SKID using (i) the ID value of the network entity and (ii) a private key SKPKG that is known only by the PKG server and corresponds to the public key PKPKG.

摘要： A method and terminal are provided in which a radio resource control (RRC) message is received which includes information indicating a change from a first packet data convergence protocol (PDCP) to a second PDCP entity. It is identified whether the first PDCP entity is changed based on the information indicating the change. Data with a PDCP sequence number for the first PDCP entity is processed as new data for the second PDCP entity, in case that the first PDCP entity is changed. The first PDCP entity is released. A new PDCP header associated with the data is configured. The data is encrypted with a new security key. The PDCP sequence number of the first PDCP entity is greater than or equal to the PDCP sequency number of data for which successful transmission is not acknowledged from a radio link control (RLC) entity.

摘要： Security features for a wireless communications system including encryption and decryption of communications, secure key exchange, secure pairing, and secure re-pairing are provided. The encryption/decryption mechanism uses AES-256 block cypher with counter mode to generate blocks of cypher bits used to encrypt and decrypt communications between a master and devices. Session keys are generated using a random salt and a counter value. The random salt is generated using a secure random number generator. A master key or device key is also used in generating session keys. Impermanent session keys are used to encrypt/decrypt finite amount of data. Thereafter, the session key is replaced and cypher bits are generated using the new session key. A synchronized key jump procedure ensures that the master and device switch to the new session key at the same time.
