Cloud computing provides users with ample computing resources, storage, and bandwidth to meet their computing needs, often at minimal cost. As such services become popular and available to a larger body of users, security mechanisms become an integral part of them. Conventional means for protecting data privacy, such as encryption, can protect communication and stored data from unauthorized access including the service provider itself. Such tools, however, are not sufficient against powerful adversaries who can force users into opening their encrypted content. In this work the authors introduce the concept of deniable cloud storage that guarantees privacy of data even when one's communication and storage can be opened by an adversary.
