- Turn on hardware acceleration for AES. This is supported only on selected
architectures and currently only available for AES. See configuration options
`MBEDTLS_AESCE_C`, `MBEDTLS_AESNI_C` and `MBEDTLS_PADLOCK_C` for details.
`MBEDTLS_AESCE_C`, `MBEDTLS_AESNI_C` for details.
- Add a secure alternative implementation (typically hardware acceleration) for
the vulnerable cipher. See the [Alternative Implementations
Guide](docs/architecture/alternative-implementations.md) for more information.

@ -46,7 +46,7 @@ Generally, alternative implementations can define their context types to any C t
Where a context type needs to have a certain field, the field must have the same type and semantics as in the built-in implementation, but does not need to be at the same position in the structure. Furthermore, unless otherwise indicated, only read access is necessary: the field can be `const`, and modifications to it do not need to be supported. For example, if an alternative implementation of asymmetric cryptography uses a different representation of large integers, it is sufficient to provide a read-only copy of the fields listed here of type `mbedtls_mpi`.
* AES: if `MBEDTLS_AESNI_C` or `MBEDTLS_PADLOCK_C` is enabled, `mbedtls_aes_context` must have the fields `nr` and `rk`.
* AES: if `MBEDTLS_AESNI_C` is enabled, `mbedtls_aes_context` must have the fields `nr` and `rk`.
* DHM: if `MBEDTLS_DEBUG_C` is enabled, `mbedtls_dhm_context` must have the fields `P`, `Q`, `G`, `GX`, `GY` and `K`.
* ECP: `mbedtls_ecp_group` must have the fields `id`, `P`, `A`, `B`, `G`, `N`, `pbits` and `nbits`.
* If `MBEDTLS_PK_PARSE_EC_EXTENDED` is enabled, those fields must be writable, and `mbedtls_ecp_point_read_binary()` must support a group structure where only `P`, `pbits`, `A` and `B` are set.
