4Federal Information Processing Standards (FIPS) CryptoDev Validation
5====================================================================

7Overview
8--------
9
10Federal Information Processing Standards (FIPS) are publicly announced standards
11developed by the United States federal government for use in computer systems by
12non-military government agencies and government contractors.
13
14This application is used to parse and perform symmetric cryptography
15computation to the NIST Cryptographic Algorithm Validation Program (CAVP) test
16vectors.
17
18For an algorithm implementation to be listed on a cryptographic module
19validation certificate as an Approved security function, the algorithm
20implementation must meet all the requirements of FIPS 140-2 and must
21successfully complete the cryptographic algorithm validation process.
22
23Limitations
24-----------
25
26* Only NIST CAVP request files are parsed by this application.
27* The version of request file supported is ``CAVS 21.0``
28* If the header comment in a ``.req`` file does not contain a Algo tag
29  i.e ``AES,TDES,GCM`` you need to manually add it into the header comment for
30  example::
31
32      # VARIABLE KEY - KAT for CBC / # TDES VARIABLE KEY - KAT for CBC
33
34* The application does not supply the test vectors. The user is expected to
35  obtain the test vector files from `NIST
36  <https://csrc.nist.gov/projects/cryptographic-algorithm-validation-
37  program/block-ciphers>`_ website. To obtain the ``.req`` files you need to
38  email a person from the NIST website and pay for the ``.req`` files.
39  The ``.rsp`` files from the site can be used to validate and compare with
40  the ``.rsp`` files created by the FIPS application.
41
42* Supported test vectors
43    * AES-CBC (128,192,256) - GFSbox, KeySbox, MCT, MMT
44
45Application Information
46-----------------------
47
48If a ``.req`` is used as the input file after the application is finished
49running it will generate a response file or ``.rsp``. Differences between the
50two files are, the ``.req`` file has missing information for instance if doing
51encryption you will not have the cipher text and that will be generated in the
52response file. Also if doing decryption it will not have the plain text until it
53finished the work and in the response file it will be added onto the end of each
54operation.
55
56The application can be run with a ``.rsp`` file and what the outcome of that
57will be is it will add a extra line in the generated ``.rsp`` which should be
58the same as the ``.rsp`` used to run the application, this is useful for
59validating if the application has done the operation correctly.

61
62Compiling the Application
63-------------------------
64
65* Compile Application
66
67    .. code-block:: console
68
69         make -C examples/fips_validation
70
71*  Run ``dos2unix`` on the request files
72
73    .. code-block:: console
74
75         dos2unix AES/req/*
76         dos2unix AES_GCM/req/*
77         dos2unix CCM/req/*
78         dos2unix CMAC/req/*
79         dos2unix HMAC/req/*
80         dos2unix TDES/req/*
81
82Running the Application
83-----------------------
84
85The application requires a number of command line options:
86
87    .. code-block:: console
88
89         ./fips_validation [EAL options]
90         -- --req-file FILE_PATH/FOLDER_PATH
91         --rsp-file FILE_PATH/FOLDER_PATH
92         [--cryptodev DEVICE_NAME] [--cryptodev-id ID] [--path-is-folder]
93
94where,
95  * req-file: The path of the request file or folder, separated by
96    ``path-is-folder`` option.
97
98  * rsp-file: The path that the response file or folder is stored. separated by
99    ``path-is-folder`` option.
100
101  * cryptodev: The name of the target DPDK Crypto device to be validated.
102
103  * cryptodev-id: The id of the target DPDK Crypto device to be validated.
104
105  * path-is-folder: If presented the application expects req-file and rsp-file
106    are folder paths.
107
108
109To run the application in linuxapp environment to test one AES FIPS test data
110file for crypto_aesni_mb PMD, issue the command:
111
112.. code-block:: console
113
114    $ ./fips_validation --vdev crypto_aesni_mb --
115    --req-file /PATH/TO/REQUEST/FILE.req --rsp-file ./PATH/TO/RESPONSE/FILE.rsp
116    --cryptodev crypto_aesni_mb
117
118To run the application in linuxapp environment to test all AES-GCM FIPS test
119data files in one folder for crypto_aesni_gcm PMD, issue the command:
120
121.. code-block:: console
122
123    $ ./fips_validation --vdev crypto_aesni_gcm0 --
124    --req-file /PATH/TO/REQUEST/FILE/FOLDER/
125    --rsp-file ./PATH/TO/RESPONSE/FILE/FOLDER/
126    --cryptodev-id 0 --path-is-folder
