  • Publication number: 20240049165
    Abstract: A secure ranging system can use a secure processing system to deliver one or more ranging keys to a ranging radio on a device, and the ranging radio can derive locally at the system ranging codes based on the ranging keys. A deterministic random number generator can derive the ranging codes using the ranging key and one or more session parameters, and each device (e.g. a cellular telephone and another device) can independently derive the ranging codes and derive them contemporaneously with their use in ranging operations.

  • Patent number: 11895495
    Abstract: This disclosure relates to techniques, base stations, and user equipment devices (UEs) for performing base station authentication through access stratum signaling transmissions. The UE may operate in idle mode and may receive an authentication message from a base station through the wireless interface while operating in idle mode. The UE may determine whether a signature comprised within the authentication message is valid, and the UE may continue a connection procedure with the base station based on a determination that the signature is valid. If it is determined that the signature is invalid, the UE may designate the base station as a barred base station and may perform cell re-selection. The authentication message may be one of a radio resource control (RRC) connection setup message, a special RRC message, a media access control (MAC) message, or a random access channel (RACH) message comprising a random access response (RAR) message.

  • Patent number: 11870902
    Abstract: Techniques disclosed herein relate to the authentication of a first user in a communication session between the first user using a user device and a second user using a remote computer system. The computer system sends an authentication request in the session, and the user device receives the authentication request in the session via a messaging program. The user device then causes a different program to access an authentication token received from an authentication computer system. The user device sends an indication of the authentication token to the remote computer system which the remote computer system verifies to authenticate the first user within the session.

  • Patent number: 11777936
    Abstract: Techniques are disclosed relating to sharing access to electronically-secured property. In some embodiments, a first computing device having a first secure element receives, from a second computing device associated with an owner of the electronically-secured property, an indication that the second computing device has transmitted a token to server computing system, the token permitting a user of the first computing device access to the electronically-secured property. Based on the received indication, the first computing device sends a request for the transmitted token to the server computing system and, in response to receiving the requested token, securely stores the received token in the first secure element of the first computing device. The first computing device subsequently transmits the stored token from the first secure element of the first device to the electronically-secured property to obtain access to the electronically-secured property based on the token.

  • Publication number: 20230300122
    Abstract: Some embodiments of the invention provide a method for a trusted (or originator) device to modify the security state of a target device (e.g., unlocking the device) based on a securing ranging operation (e.g., determining a distance, proximity, etc.). The method of some embodiments exchanges messages as a part of a ranging operation in order to to determine whether the trusted and target devices are within a specified range of each other before allowing the trusted device to modify the security state of the target device. In some embodiments, the messages are derived by both devices based on a shared secret and are used to verify the source of ranging signals used for the ranging operation. In some embodiments, the method is performed using multiple different frequency bands.

  • Patent number: 11677554
    Abstract: Techniques are disclosed relating to secure message exchanges. In some embodiments, a first computing device generates an account key associated with a user account shared by a plurality of computing devices. The first computing device signs a public key of the first computing device with the generated account key to produce a digital signature and sends the public key and the digital signature to a first server system for distributing the public key to a second computing device attempting to send an encrypted message to the first computing device. The first computing device sends the account key to an external storage external usable by others of the plurality of computing devices to obtain the account key and use the account key to sign public keys of the other computing devices. The first computing device receives, from the second computing device, the encrypted message encrypted using the public key.
