Teppo Järvelin 91d7938761 Changed every memcpy to SCA equivalent mbedtls_platform_memcpy
This makes physical attacks more difficult.

Arto Kinnunen 77b9cfcea9 AES: add config option for 128-bit keys

calculation.

Manuel Pégourié-Gonnard 7a346b866c Replace memset() with mbedtls_platform_memset()
Steps:

1. sed -i 's/\bmemset(\([^)]\)/mbedtls_platform_memset(\1/g' library/*.c tinycrypt/*.c include/mbedtls/*.h scripts/data_files/*.fmt

2. Manually edit library/platform_util.c to revert to memset() in the
implementations of mbedtls_platform_memset() and mbedtls_platform_memcpy()

3. egrep -n '\<memset\>' library/*.c include/mbedtls/*.h tinycrypt/*.c
The remaining occurrences are in three categories:
    a. From point 2 above.
    b. In comments.
    c. In the initialisation of memset_func, to be changed in a future commit.

Ron Eldor 9924bdc792 Deprecate hardware acceleration errors
Deprecate the module-specific XXX_HW_ACCEL_FAILED and
XXX_FEATURE_UNAVAILABLE errors, as alternative implementations should now
return `MBEDTLS_ERR_PLATFORM_HW_FAILED` and
`MBEDTLS_ERR_PLATFORM_FEATURE_UNSUPPORTED`.

Andres Amaya Garcia 1f6301b3c8 Rename mbedtls_zeroize to mbedtls_platform_zeroize 2018-04-17 10:00:21 -05:00
Andres Amaya Garcia e32df087fb Remove individual copies of mbedtls_zeroize()
This commit removes all the static occurrencies of the function
mbedtls_zeroize() in each of the individual .c modules. Instead the
function has been moved to utils.h that is included in each of the
modules.

Ron Eldor 5a21fd62bf fix for issue 1118: check if iv is zero in gcm.
1) found by roberto in mbedtls forum
2) if iv_len is zero, return an error
3) add tests for invalid parameters

Andres Amaya Garcia d3e7e7d83f Add comment for skipped AES-192 test condition 2017-06-15 16:17:46 +01:00
Andres Amaya Garcia 2a078da134 Run AES-GCM-192 selftest if available only
This patch modifies the function mbedtls_gcm_self_test() function to
ensure that AES-GCM-192 tests are only run if the key size is supported
by the available implementation. This is useful when using
MBEDTLS_AES_ALT as some hardware crypto accelerators might not support
AES-192.

Andres AG 821da84ff9 Fix documentation for mbedtls_gcm_finish()
Fix implementation and documentation missmatch for the function
arguments to mbedtls_gcm_finish(). Also, removed redundant if condition
that always evaluates to true.

Manuel Pégourié-Gonnard 1e07562da4 Fix wrong length limit in GCM
See for example page 8 of
http://csrc.nist.gov/publications/nistpubs/800-38D/SP-800-38D.pdf

The previous constant probably came from a typo as it was 2^26 - 2^5 instead
of 2^36 - 2^5. Clearly the intention was to allow for a constant bigger than
2^32 as the ull suffix and cast to uint64_t show.

fixes #362
