AES-CCM encrypted Mirage Mirage_block.S storage

uses two sectors of the underlying Mirage_bloc.S per provided sector:

+-----------------------------------+
| CT                | nonce | adata |
+-----------------+-----------------+
| sector n        | sector n+1      |
+-----------------+-----------------+
  • CT is sector_size + maclen bytes AES-CCM ciphertext

  • nonce is nonce_len bytes random nonce

  • adata is sector_size - nonce_len - maclen random additional authenticated data

Notes on bisect and ounit tests

$ dune runtest --instrument-with bisect_ppx --force
$ bisect-ppx-report html
$ open _coverage/index.html

convert AES-CCM encrypted disk images from/to unencrypted images
