Systems, apparatuses, and methods are described for adjusting capacity in a networking environment. A networking system comprising clients, servers, load balancers, and/or other devices may expand and contract network capacity as needed. When expanding network capacity, load balancers may instruct client devices to connect to servers that are part of the expanded network. When network capacity is reduced, a server and/or a load balancer my instruct client devices to close a connection with a first server and establish a connection with a second server. Client devices may seamlessly begin using the connection with a second server without having to wait for a connection timeout with the first server.

Embodiments disclosed systems and methods to broadcast a message to one or more virtual data processing (DP) accelerators. In response to receiving a broadcast instruction from an application, the broadcast instruction designating one or more virtual DP accelerators of a plurality of virtual DP accelerators to receive a broadcast message, the system encrypts the broadcast message based on a broadcast session key for a broadcast communication session. The system determines one or more public keys of one or more security key pairs each associated with one of the designated virtual DP accelerators. The system encrypts the broadcast session key based on the determined one or more public keys. The system broadcasts the encrypted broadcast message, and the one or more encrypted broadcast session keys to adjacent virtual DP accelerators for propagation.

One disclosed example method includes a leader client device associated with a leader participant generating a meeting key for a video meeting joined by multiple participants. For each participant, the leader client device obtains a long-term public key and a cryptographic signature associated with the participant. The leader client device verifies the cryptographic signature of the participant based on the long-term public key and the cryptographic signature. If the verification is successful, the leader client device encrypts the meeting key for the participant using a short-term private key generated by the leader client device, a short-term public key of the participant, a meeting identifier, and a user identifier identifying the participant. The leader client device further publishes the encrypted meeting key for the participant on the meeting system. The leader client device encrypts and decrypts meeting data communicated with other participants based on the meeting key.

One disclosed example involves a client device joining a videoconferencing meeting in which there is end-to-end encryption, where the end-to-end encryption is implemented by the client devices participating in the meting using a meeting key provided by the meeting host. Thereafter, the client device receives a public key of an asymmetric key pair corresponding to the host of the meeting, where the public key is different from the meeting key. The client device then generates a security code based on the public key and output the security code on a display device. The security code can be compared to another security code generated by another client device participating in the meeting to verify if the meeting is secure. The client device may also receive encrypted videoconferencing data, decrypt it using the meeting key, and output the decrypted videoconferencing data on the display device.

A Computing environment is described to enable an information handling system (IHS) to receive a public encryption key from another IHS; and decrypt with a public encryption key one or more encrypted symmetric encryption keys, encrypted via a private encryption key, to obtain one or more symmetric encryption keys respectively associated with one or more memory address ranges. The IHS may physically receive a memory device that was utilized by the other IHS to store information in an encrypted fashion. The IHS may further decrypt, with a first encryption key of the one or more symmetric encryption keys associated with a first address range of the one or more address ranges, first encrypted data stored by the at least one non-volatile memory medium to obtain first data.

A user equipment for a mobile telecommunications system, including circuitry configured to: communicate with a non-public network authentication-authorization-accounting server and initiate a registration procedure with the mobile telecommunications system; and provide an authentication interface between the non-public network authentication-authorization-accounting server and an authentication server function entity in the mobile tele-communications system.

A method for recovering a network key of an access point to a network, implemented by a terminal. The network key allows the terminal to be associated with the access point upon a first connection of the terminal to the access point. The network key recovery method includes: receiving, by the terminal, a network key provided by the access point on a server following a request, by the terminal to the server, for the network key of the access point, the request including an identifier of the access point and having been relayed by the server to the access point associated with the identifier of the access point in the request. Thus, as the access point does not transmit the network key directly to the terminal, but to a server on which the terminal will recover it, this limits intrusions into the network linked to the vulnerability of the Wi-Fi network.

This application provides a key distribution method, an apparatus, and a system, includes: determining, by an identity management server based on AAA authentication information, whether AAA authentication on the terminal succeeds; if the AAA authentication succeeds, sending the ID of the terminal to a key management server; and generating, by the key management server, a private key of the terminal and returning the private key to the management server. After negotiating with the terminal to generate a first key, the identity management server encrypts the ID and the private key of the terminal, and sends an encrypted ID and an encrypted private key to the terminal. The terminal obtains the ID and the private key of the terminal. According to the key distribution method, apparatus, and system provided in this application, communication security performance of the terminal during ID-based registration authentication is improved.

Disclosed is a method for ultra-wide band (UWB) security ranging and a UWB device configured to perform secure ranging. The method includes obtaining, from a UWB sub-system of the UWB device, first encryption data including a symmetric key encrypted with a public key of a secure application of the UWB device; transferring the first encryption data to the secure application; obtaining, from the secure application, second encryption data including a ranging data set (RDS) encrypted with the symmetric key; and transferring the second encryption data to the UWB sub-system. In this case, the RDS may include a ranging session key configured to secure a UWB ranging session, and the secure application may be included in a trusted execution environment area.

An operating system with automatic login mechanism and an automatic login method are provided. The operating system includes a first electronic device, a second electronic device and a server device. The second electronic device includes a biometric sensor. When a login event of the first electronic is triggered, the first electronic device sends a login request to the second electronic device directly or via the server device, so that the second electronic device performs a biometric verification by the biometric sensor according to the login request. When the biometric verification is passed, the second electronic device sends a first login credential to the first electronic device directly or via the server device, so that the first electronic device performs an automatic login operation of the first electronic device according to the first login credential.
