According to one embodiment, a gateway maintains multiple cryptographic keys. A file that is to be stored across multiple third-party cloud storage services is received by the gateway from a user of an enterprise network. The file is partitioned into chunks. A directory is created within a cloud storage service having a name attribute based on an encrypted version of a name of the file. For each chunk: (i) existence of data is identified within the chunk associated with one or more predefined search indices; (ii) searchable encrypted metadata is generated based on the identified data and a selected cryptographic key; (iii) an encrypted version of the chunk is generated; and (iv) a file is created within the directory in which a name attribute includes the searchable encrypted metadata and the file content includes the encrypted chunk."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Secure cloud storage distribution and aggregation","description":"Methods and systems for secure cloud storage are provided.
