  • Patent number: 11424916
    Abstract: A method may include receiving, from a first trusted authority, a secret key specific to a party for use in posting to a blockchain. The method may also include receiving, from a second trusted authority, a correlated randomness component specific to the party and associated with a given temporal segment. The method may additionally include generating a party-generated randomized mask, and computing, using an input from the party, the correlated randomness component, and the party-generated randomized mask in a non-interactive multi-party computation (NIMPC), an NIMPC-encrypted input associated with the party for the given temporal segment.

  • Patent number: 11381971
    Abstract: A method of authorizing an access point includes receiving a first transmission signal from a first access point. The first transmission signal comprises identifying information of the first access point that includes a first token. The method includes receiving a second transmission signal from a client device. The second transmission signal includes a second token that is received by the client device from an un-provisioned access point. When a match is determined between the first token and the second token, the first access point is identified as the un-provisioned access point. The method includes transmitting the identifying information of the first access point and a request to the client device to authorize the un-provisioned access point. The method includes receiving a third transmission signal from the client device that includes an authorization verification of the un-provisioned access point that authorities the un-provisioned access point to connect to a cloud-managed network.

  • Patent number: 11368298
    Abstract: Methods are provided for decentralized key negotiation. One method includes initiating, by a first Internet Key Exchange (IKE) node from among a plurality of IKE nodes, a rekeying process for an Internet Protocol Security (IPSec) communication session established with a client device and serviced by a second IKE node from among the plurality of IKE nodes, and in which a first encryption key is used to encrypt traffic. The method further includes obtaining, by the first IKE node from a key value store, information about the IPSec communication session and performing, by the first IKE node, at least a part of the rekeying process in which the first encryption key is replaced with a second encryption key for the IPSec communication session.

  • Patent number: 11329984
    Abstract: A limited input device, such as a camera, is authenticated based on a request received from an authenticated application. The application can request an application server to provide the application with a one-time authorization code. The request includes the device identifier associated with the camera. The server stores an association between the one-time authorization code and the device identifier of the camera, and provides the application with the one-time authorization code. The application provides the camera with the one-time authorization code. The camera transmits a request for an access token to the server, the request for the access token including the one-time authorization code and the device identifier associated with the camera. The server verifies the device identifier associated with the camera with that associated with the one-time authorization code, and upon a positive verification authenticates the camera by providing the camera with the access token.

  • Patent number: 11290349
    Abstract: Systems and techniques are described for a centralized management system operating within a virtual machine which configures, monitors, analyzes, and manages an adaptive private network (APN) to provide a discovery process that learns about changes to the APN through a network control node (NCN) that is a single point of control of the APN. The discovery process automatically learns a new topology of the network without relying on configuration information of nodes in the APN. Network statistics are based on a timeline of network operations that a user selected to review. Such discovery and timeline review is separate from stored configuration information. If there was a network change, the changes either show up or not show up in the discovery process based on the selected time line. Configuration changes can be made from the APN VM system by loading the latest configuration on the APN under control of the NCN.
