Simon Butcher 94ffde7b0a Fix CMAC interface for doxygen 
Parameters didn't match the function definition.
 2016-10-05 15:33:53 +01:00
Simon Butcher 327398ad3a Refactor and change CMAC interface 
Change the CMAC interface to match the mbedtls_md_hmac_xxxx() interface. This
changes the overall design of the CMAC interface to make it more consistent with
the existing HMAC interface, and will allow incremental updates of input data
rather than requiring all data to be presented at once, which is what the
current interface requires.

Manuel Pégourié-Gonnard 7b555f2928 cmac: more cosmetic changes 2016-10-05 14:19:15 +01:00
Manuel Pégourié-Gonnard ab9c5fd9b3 cmac: avoid useless wrapping of function 
probably a leftover from an earlier stage
 2016-10-05 14:19:15 +01:00
Manuel Pégourié-Gonnard d18c70708e cmac: reduce visibility of macros 
The #undef is usefull for people who want to to amalgamated releases
 2016-10-05 14:19:15 +01:00
Manuel Pégourié-Gonnard 2c06306364 cmac: some more padding-related tune-ups 
- use one less temporary buffer
- pedantic: in_len + 15 was a potential overflow
- use a more explicit name instead of 'flag'
- Mn was a bit misleading

Manuel Pégourié-Gonnard d2c3d3eddb cmac: clean up padding function and comments 2016-10-05 14:19:14 +01:00
Manuel Pégourié-Gonnard 475f06f609 cmac: make subkey gen more constant-time 
The previous version had secret-dependent memory accesses. While it was
probably not an issue in practice cause the two bytes of the array are
probably on the same cache line anyway, as a matter of principle this should
be avoided.

Manuel Pégourié-Gonnard d6cf75474b cmac: zeroize sensitive intermediate values 2016-10-05 14:19:14 +01:00
Manuel Pégourié-Gonnard a610b4c04b cmac: factor multiply by u to its own function 
We're doing exactly the same operation for K1 and K2.

Manuel Pégourié-Gonnard 690083c21d cmac: improve argument order and naming 
- always use the pattern "buffer, length"
- avoid using unqualified "length" as a name when there are more than one
