Soby Mathew 0a4270d732 Change the compatibility API to inline functions
This patch changes the compatibility API defined in crypto_compat.h
to static inline functions as the previous macro definitions were
causing issues for the C pre-processor when included in projects
which need to redefine the PSA function names. Making it static
inline function solves this problem neatly and also modern compilers
do a good job at inlining the function which makes the need for making
it a macro redundant.

Gilles Peskine 42459805ce USE_PSA_CRYPTO: don't rely on the curve encoding
Adapt to the change of encoding of elliptic curve key types in PSA
crypto. Before, an EC key type encoded the TLS curve identifier. Now
the EC key type only includes an ad hoc curve family identifier, and
determining the exact curve requires both the key type and size. This
commit moves from the old encoding and old definitions from
crypto/include/mbedtls/psa_util.h to the new encoding and definitions
from the immediately preceding crypto submodule update.

Gilles Peskine 7cfcb3fc03 Change the encoding of key types to have a parity bit
Change the encoding of key types, EC curve families and DH group
families to make the low-order bit a parity bit (with even parity).

This ensures that distinct key type values always have a Hamming
distance of at least 2, which makes it easier for implementations to
resist single bit flips.

Gilles Peskine f65ed6f254 Change key types to a 16-bit encoding
All key types now have an encoding on 32 bits where the bottom 16 bits
are zero. Change to using 16 bits only.

Keep 32 bits for key types in storage, but move the significant
half-word from the top to the bottom.

Likewise, change EC curve and DH group families from 32 bits out of
which the top 8 and bottom 16 bits are zero, to 8 bits only.

Reorder psa_core_key_attributes_t to avoid padding.

Gilles Peskine b87b719467 Remove old values of curve encodings
Remove the values of curve encodings that are based on the TLS registry
and include the curve size, keeping only the new encoding that merely
encodes a curve family in 8 bits.

Keep the old constant names as aliases for the new values and
deprecate the old names.

Gilles Peskine 228abc5773 Define EC curve family constants
Define constants for ECC curve families and DH group families. These
constants have 0x0000 in the lower 16 bits of the key type.

Support these constants in the implementation and in the PSA metadata
tests.

Switch the slot management and secure element driver HAL tests to the
new curve encodings. This requires SE driver code to become slightly
more clever when figuring out the bit-size of an imported EC key since
it now needs to take the data size into account.

Switch some documentation to the new encodings.

Remove the macro PSA_ECC_CURVE_BITS which can no longer be implemented.

Gilles Peskine 025fccdc32 Change the encoding of EC curves and DH groups to include the size
Change the representation of psa_ecc_curve_t and psa_dh_group_t from
the IETF 16-bit encoding to a custom 24-bit encoding where the upper 8
bits represent a curve family and the lower 16 bits are the key size
in bits. Families are based on naming and mathematical similarity,
with sufficiently precise families that no two curves in a family have
the same bit size (for example SECP-R1 and SECP-R2 are two different
families).

As a consequence, the lower 16 bits of a key type value are always
either the key size or 0.

Gilles Peskine d8197cb902 mbedtls_psa_parse_tls_ecc_group: make no assumption on PSA encodings
Don't assume that the PSA encoding of elliptic curves is identical to
the TLS encoding. This is currently true but about to change.

The new implementation only works when MBEDTLS_ECP_C is defined. This
is ok because the function is only used with MBEDTLS_ECP_C defined.

Gilles Peskine fc2459db13 Remove mbedtls_psa_translate_ecc_group

Gilles Peskine 7bfcfac164 Change key type encodings to avoid bit 16
Key types are now encoded through a category in the upper 4 bits (bits
28-31) and a type-within-category in the next 11 bits (bits 17-27),
with bit 16 unused and bits 0-15 only used for the EC curve or DH
group.

For symmetric keys, bits 20-22 encode the block size (0x0=stream,
0x3=8B, 0x4=16B).

Gilles Peskine 8fe6e0de3a Symmetric key types only use the upper 16 bits of psa_key_type_t
Change the numerical encoding of values for symmetric key types to
have 0000 as the lower 16 bits. Now the lower 16 bits are only used
for key types that have a subtype (EC curve or DH group).

Gilles Peskine 13faa2d920 Don't declare a parameter as const
An earlier commit fixed this for psa_hash_compare. psa_mac_verify had
the same flaw.
2020-01-30 16:32:21 +01:00
Gilles Peskine fa710f5c6a Don't declare a parameter as const
Whether a parameter should be const is an implementation detail of the
function, so don't declare a parameter of psa_hash_compare as
const. (This only applies to parameters themselves, not to objects
that pointer parameters points to.)

Jaeden Amero a15c71374b ctr_drbg: Clarify reseed_counter values before seeding
Before the initial seeding, reseed_counter used to always be 0. Now, the
value depends on whether or not the user has explicitly set the amount
of data to get from the nonce (via e.g.
mbedtls_ctr_drbg_set_nonce_len()). Add comments to clarify the possible
values reseed_counter can have before the initial seeding.

not be returned by the library. If it is returned, then it is surely a
bug in the library or somebody is tampering with the device.
