Abstract
A file layout and encryption scheme to protect a data file are introduced. A system, computer-readable medium, and method are provided for selecting an encrypted data node of a data file for writing data, generating a node encryption key for the selected encrypted node, encrypting the selected encrypted node with the node encryption key, saving the node encryption key and a node integrity check value for the node encryption key in a parent encrypted cryptographic node, selecting an ancestor encrypted cryptographic node as the selected encrypted node, and repeating the generating, encrypting, saving, and selecting the ancestor encrypted cryptographic node until the selected ancestor encrypted cryptographic node is a root encrypted cryptographic node for the data file. Encrypting a data node with the node encryption key further saves the data to be written to the encrypted data node.
