    Abstract: Presented herein are techniques for synchronizing a cloud service and a key management service via a single indirect synchronous message sent by a client device. In particular, a cloud service receives a service request message sent by a client device. Embedded into the service request message is an encrypted key management message. The cloud service is configured to extract the encrypted key management message from the service request message and then send the encrypted key management message to the key management service.

    Abstract: In one embodiment, a beacon signal is received from a beacon device. Either a mobile device or a server identifies a beacon authentication value from the beacon signal. Either the mobile device or the server calculates a local verification value from a security algorithm. A comparison of the authentication value to the local verification value is performed, and a location service is provided based on the comparison.

    Abstract: Techniques are provided for augmenting the capabilities of the standard OAuth2 authorization framework in such a way as to allow clients to consume the services of multiple resource servers residing in disjoint security domains while requiring only a single one-time user authentication. An access token that provides access to resource services distributed across a plurality of security domains is partitioned into a plurality of reduced-scope access tokens. Each reduced-scope access token is limited to a subset of authorization scopes of the access token, providing access to a resource service in a particular security domain based upon the subset.

    Abstract: A system and method for achieving authorization in confidential group communications in terms of an ordered list of data blocks representing a tamper-resistant chronological account of group membership updates. This method permits ad-hoc and decentralized group definition, dynamic and decentralized membership updates, open sharing, tamper resistance, and tracking of membership history. There are many applications of these techniques. One such application is enabling end-to-end encryption of instant messaging, content sharing, and streamed media.
