  • Patent number: 11917402
    Abstract: A method of digital radio communication between a first device and a second device is disclosed. An advertising packet is transmitted between first and second devices, wherein the packet includes a first address and a data portion. Additionally, an encryption key is transmitted between the devices. The first device generates a second address by encrypting an identity value derived from part of the first address using the encryption key and the data portion. The result is encrypted to generate second portion of the second address. The first device then transmits a connection request including the second address. The second device decrypts the second portion and uses the encryption key to determine correspondence with the first portion. If said correspondence is determined, the second device decrypts the first portion using at least the encryption key and compares it to an expected identity value derived from the first address.

  • Patent number: 11907202
    Abstract: The described technology is generally directed towards caching session state data on a client device, so that services called by the client device and other services can use the session state data without having to recollect such information from a server or servers that maintain the ground truth values for the session state data. The session state data can be divided into payload datasets based on domains or the like, so that only a relevant part of the session state data need be attached to a given communication, and/or updated when a session variable changes in some way. A payload dataset can be encoded or encrypted so that a service can verify the integrity of the payload dataset before using it, such as for service-to-service communication.

  • Patent number: 11895229
    Abstract: A network node operates a Session Management Function (SMF) in a control plane of a core network of a wireless network. The network node authenticates a User Equipment (UE) with an Extensible Authentication Protocol (EAP) server in a secondary authentication process that uses the SMF as an EAP authenticator. The EAP server is outside of the core network and the UE is separately authenticated with a further network node in the control plane of the core network via a primary authentication process. Authenticating the UE in the secondary authentication process comprises exchanging EAP messages between the SMF and the UE and between the SMF and the EAP server. The SMF authorizes a data session between the UE and the external network through a user plane of the core network based on the UE having successfully authenticated via both the primary authentication process and the secondary authentication process.

  • Patent number: 11870904
    Abstract: A method for encrypting and decrypting data across domains based on privacy computing is provided. A data provider deploys a base key for a data user in advance, and when the data user needs to use the data at a later stage, the data provider generates a data token about a data key based on the base key, and then transmits encrypted data and the data token to the data user. The user obtains the data key based on its own base key in a privacy environment according to the data token, and uses the data key in the privacy environment to realize use of the encrypted data. A transmission process does not involve transmission of the key; therefore, even if a transmission channel is not secure, security of the data can still be ensured, and even if private data is used, the data itself cannot be obtained.

  • Patent number: 11765146
    Abstract: Techniques and mechanisms to reduce double encryption of packets that are transmitted using encrypted tunnels. The techniques described herein include determining that portions of the packets are already encrypted, identifying portions of the packets that are unencrypted, and selectively encrypting the portions of the packets that are unencrypted prior to transmission through the encrypted tunnel. In this way, potentially private or sensitive data in the packets that is unencrypted, such as information in the packet headers, will be encrypted using the encryption protocol of the encrypted tunnel, but the data of the packets that is already encrypted, such as the payload, may avoid unnecessary double encryption. By reducing (or eliminating) the amount of data in data packets that is double encrypted, the amount of time taken by computing devices, and computing resources consumed, to encrypted traffic for encrypted tunnels may be reduced.

  • Patent number: 11606477
    Abstract: A camera has two or more color elements that are removable and replaceable. The color elements may include a lens, a color filter with a filter data interface, and an image sensor. A security processor includes a private key, firmware, and has storage room for one or more vegetation indices. The security processor securely decrypts, stores, and uses the indices. Firmware checks license terms and installed filters required in a selected index, and analyzes images based on a formula in the index, thresholds for the index value, and thresholds for an object's height above ground level. A positioning receiver (e.g. GPS) determines time and position, which the firmware uses for the license check and for the height AGL calculation. Differences in camera position allow determining a parallax calculation on correlated groups of pixels. The camera provides on-the-fly analysis, and tags and stores images for which alert conditions are met.
