20120204224 | Method and Apparatus for a Control Plane to Manage Domain-Based Security and Mobility in an Information Centric Network - A networking system comprising a virtual group controller in an information centric network configured to enable mobility and security for a plurality of users groups of the information centric network, a plurality of user groups coupled to the virtual group controller and associated with the users, a plurality of agents that are each associated with one of the user groups, and a database for trusted service profile coupled to the virtual group controller, wherein the virtual group controller is configured to interact with the agents to enable mobility for the user groups using a server-less domain-based naming scheme. | 08-09-2012 |
20120317655 | Method for Flexible Data Protection with Dynamically Authorized Data Receivers in a Content Network or in Cloud Storage and Content Delivery Services - A networking system comprising an application service that runs on a cloud infrastructure and is configured to receive dual encrypted content from a content provider and re-encrypt the dual encrypted content to enable dynamic user group control for group-based user authorization, and a cloud storage service coupled to the application service and configured to store the dual encrypted content from the content provider and the re-encrypted dual encrypted content from the application service, wherein the application service and the storage service are configured to communicate and operate with a content delivery service that uses a content delivery network (CDN) to deliver the re-encrypted content to one or more users in a group authorized by the content provider. | 12-13-2012 |
20130041982 | METHOD AND NODE FOR ACQUIRING CONTENT AND CONTENT NETWORK - The present invention discloses a method and node for acquiring content and a content network, and is related to the field of communications. The method includes: receiving a content request, where the content request at least includes an identifier of requested content; determining whether the content corresponding to the identifier can be acquired locally; if yes, acquired the content corresponding to the identifier locally; otherwise, searching, according to the identifier, a name resolution system for a target node that stores the identifier, and acquiring the content corresponding to the identifier from the target node; where the name resolution system comprises a multilevel DHT and a global content resolution structure, and the global content resolution structure supports name aggregation and longest matching search. | 02-14-2013 |
20130275752 | METHOD AND SYSTEM FOR SECURE MULTIPARTY CLOUD COMPUTATION - One embodiment of the present invention provides a system for performing secure multiparty cloud computation. During operation, the system receives multiple encrypted datasets from multiple clients. An encrypted dataset associated with a client is encrypted from a corresponding plaintext dataset using a unique, client-specific encryption key. The system re-encrypts the multiple encrypted datasets to a target format, evaluates a function based on the re-encrypted multiple datasets to produce an evaluation outcome, and sends the evaluation outcome to the multiple clients, which are configured to cooperatively decrypt the evaluation outcome to obtain a plaintext evaluation outcome. | 10-17-2013 |
20140233575 | Method for Scalable Routing in Content-Oriented Networks - A method for routing content, comprising receiving an interest packet from a first face, wherein the interest packet comprises a content name field populated with a first content name, a destination field, and a broadcast flag field set to broadcast, wherein the broadcast field indicates whether the first face has previously received a request having the first content name, and receiving a data packet from a second face, wherein the data packet comprises a content name field populated with a second content name, a source field populated with the identity of a source of data associated with the second content name, and a data field populated with the data associated with the second content name. | 08-21-2014 |
