Authenticating a File System Within Untrusted Storage - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240111884 titled 'Authenticating a File System Within Untrusted Storage

Simplified Explanation

The patent application describes techniques for authenticating a file system within untrusted storage by generating a file-system root hash corresponding to the file system during a write operation. The root hash is uniquely determined based on the contents of files within the file system and the structure of the file system. The size of the root hash is independent of the size of the file system, allowing for a dynamically-changing file system and predetermined, fixed storage for the root hash.

  • File-system authenticator generates a root hash during a write operation.
  • Root hash is uniquely determined based on file contents and structure.
  • Root hash size is independent of file system size.
  • Enables support for dynamically-changing file systems.
  • Predetermined, fixed storage for the root hash.

Original Abstract Submitted

this document includes techniques, apparatuses, and systems for authenticating a file system () within untrusted storage (). in particular, a file-system authenticator () generates a file-system root hash () corresponding to the file system () during a write operation. the file-system root hash () is uniquely determined based on contents of files within the file system () and a structure of the file system (). the file-system root hash () can be readily updated, which enables the file system to support a dynamically-changing file system (). also, the size of the file-system root hash () is independent of the size of the file system () within the untrusted storage (). as such, the size of trusted storage () used to store the file-system root hash () can be predetermined and fixed regardless of the size of the file system ().
