Abstract:
Methods are provided for enabling secure big data analytics in the cloud. A method includes reading a secure file, by a Secure Distributed File System in a public cloud service provider. The reading step includes computing a hash of a name of the secure file to obtain a hashed file name, finding metadata for the secure file using the hashed file name, retrieving a sharing policy identifier from the metadata, and obtaining authorization from an external entity to decrypt the secure file. The reading step further includes extracting a security key and encrypted data file names from the metadata using the sharing policy identifier, requesting one or more encrypted data files that form the secure file from a node of the public cloud service provider, and at least one of decrypting and reconstructing plaintext data for the secure file from the one or more encrypted data files.

Claim (Index 4):
The method of  claim 2 , wherein the metadata portion is stored as any of (a) a separate file, (b) as parameters of a key-value pair that are stored in a key-value store and that correspond to the one or more data files including the encrypted data, and (c) appended at an end of the one or more data files including the encrypted data.
