A file is divided into a plurality of data blocks. The data blocks are encrypted. An authentication value is generated for each encrypted data block. The encrypted data blocks are stored in a tree data structure including the encrypted data blocks and a header block. The header block includes a set of authentication values and an aggregate authentication value. Each authentication value in the set of authentication values is derived from one or more of the encrypted data blocks. The aggregate authentication value is generated based at least in part on the set of authentication values. In various embodiments, the tree data structure may include one or more levels of internal nodes including authentication blocks."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Mobile device data encryption","description":"Mobile device data encryption is disclosed.
