摘要： Some embodiments provide a method for storing multiple data assets in a folder structure on a cloud services platform. The method stores a separate encrypted structure for each of the data assets on the cloud services platform. A same first key provides access to each of the encrypted structures. The method stores, on the cloud services platform, a folder structure with an encrypted copy of the first key. The method stores a parent structure of the folder on the cloud services platform. The parent structure includes an encrypted copy of a second key that provides access to the encrypted copy of the first key.

摘要： The subject technology may be implemented by a device that includes at least one processor configured to encrypt a data object based at least in part on an encryption key. The at least one processor may be further configured to sign the encrypted data object with a private key and transmit the signed encrypted data object to a server for retrieval by another device. The at least one processor may be further configured to generate a sharing object corresponding to the data object, wherein the sharing object includes an encryption key and a public key that corresponds to the private key. The at least one processor may be further configured to encrypt the sharing object using a key of the other device and transmit, over a secure channel, the encrypted sharing object to the other device for subsequent retrieval and verification of the signed data object from the server.
