Patent number: 11683157Abstract: A device can receive, from a network device, information that identifies a user device. The network device might have authenticated the user device based on the user device accessing a radio access network. The device can receive, from the user device, a request for a first token. The request can include an encrypted session identifier. A server device might have encrypted the session identifier. The device can determine the session identifier, and generate the first token based on the session identifier and the information that identifies the user device. The device can encrypt the first token using an application public key, and provide, to the user device, the encrypted first token.

Patent number: 11683159Abstract: A method for a hybrid content protection architecture includes obtaining, by data processing hardware, a client-side cryptographic key and locally encrypting user content using the client-side cryptographic key. The method also includes communicating the client-side cryptographic key to a third party key manager, the third party key manager configured to store the client-side cryptographic key. In response to the third party key manager storing the client-side cryptographic key, the method includes receiving a token from the third party key manager, the token identifying the client-side cryptographic key stored at the third party key manager. The method further includes uploading the encrypted user content and the token to a server of a cloud computing platform.Type: GrantFiled: November 7, 2019Date of Patent: June 20, 2023Assignee: Google LLCInventors: Nicolas Lidzborski, Laetitia Estelle Baudoin, Vivek Prahlad Bhandari

Patent number: 11683160Abstract: Secure data transfers between communication nodes is performed using a group encryption key supplied by a remote management system. A first node transmits a request for secure communications with a second node to the remote management system using a control channel. The remote management system generates and encrypts a group encryption key usable by the first and second nodes and forwards the encrypted group encryption key to the first and second nodes using one or more control channels. The first and second communication nodes decrypt the group encryption key and use it to encrypt data transmitted between the nodes using a data transport network. In some implementations the securely communicating nodes may use encryption keys and/or techniques that prevent the remote management system from eavesdropping on the nodes' communications.Type: GrantFiled: April 25, 2019Date of Patent: June 20, 2023Assignee: Orion Labs, Inc.Inventors: Greg Albrecht, Andy Isaacson, Nelson Carpentier, Dan Phung, Schuyler Erle

Patent number: 11683161Abstract: Computer-readable media, methods, and systems are disclosed for managing group-level database encryption keys under group-level encryption in a database management system. Upon startup of the database management system, persisted database entries are sequentially processed to produce an in-memory data structure comprising a set of encryption group identifier metadata tuples having an encryption group identifier and a valid-from save point cycle version. The set of encryption group identifier metadata tuples is mapped to a set of key identifier tuples including a local secure store identifier and a group-level encryption key identifier. A set of group-level encryption keys is received from a key management system, according to which a group-level encryption key is mapped to each encryption group identifier metadata tuple.Type: GrantFiled: May 28, 2021Date of Patent: June 20, 2023Assignee: SAP SEInventor: Dirk Thomsen

Patent number: 11683162Abstract: A network can operate a WiFi access point with credentials. An unconfigured device can support a Device Provisioning Protocol (DPP), and record bootstrap public keys and initiator private keys. The network can record bootstrap public and responder private keys and operate a DPP server. A responder proxy can establish a secure and mutually authenticated connection with the network. The network can (i) derive responder ephemeral public and private keys, (ii) record the initiator bootstrap public key, and (iii) select a responder mode for the responder. The network can derive an encryption key with at least the (i) recorded the initiator bootstrap public key and (ii) derived responder ephemeral private key. The network can encrypt credentials using at least the derived encryption key and send the encrypted credentials through the responder proxy to the initiator, which can forward the encrypted credentials to the device, thereby supporting a device configuration.Type: GrantFiled: March 10, 2021Date of Patent: June 20, 2023Assignee: Meta Platforms, Inc.Inventor: John A.

Patent number: 11683164Abstract: Systems and methods described herein relate to techniques in which multiple parties each generate and exchange quantities that are based on a shared secret (e.g., powers of the shared secret) without exposing the shared secret. According to a protocol, two or more parties may exchange sets of elliptic curve points generated over polynomials that can be used, by each of the two or more parties, to determine a power of a shared secret. The protocol may be utilised as part of determining parameters for a smart contract that is broadcast to a blockchain network (e.g., Bitcoin). Based on the protocol, an additional party (e.g., a third party different from the two or more parties) may perform a computational task such as execution of the smart contract.Type: GrantFiled: December 7, 2018Date of Patent: June 20, 2023Assignee: nChain Licensing AGInventors: Alexandra Covaci, Simone Madeo, Patrick Motylinski, Stephane Vincent
