Title:
高信頼なクラウド・コンピューティングおよびクラウド・サービスのフレームワーク
Document Type and Number:
Japanese Patent JP2012518330
Kind Code:
A
Abstract:
A digital escrow pattern is provided for network data services including searchable encryption techniques for data stored in a cloud, distributing trust across multiple entities to avoid a single point of data compromise. In one embodiment, a key generator, a cryptographic technology provider and a cloud services provider are each provided as separate entities, enabling a publisher of data to publish data confidentially (encrypted) to a cloud services provider, and then expose the encrypted data selectively to subscribers requesting that data based on subscriber identity information encoded in key information generated in response to the subscriber requests, e.g., a role of the subscriber.
