Hello, This patch series adds support for Elliptic Curve Digital Signature Algorithm (ECDSA). To reuse existing ECC functionality, which is added as part of ECDH, it separates out ECC and ECDH so that only ECC functionality is available for ECDSA even when ECDH is in a disabled state. Patch #1 restructures ECC and ECDH code such that ECC is not dependent on ECDH config. Patches #2 & #3 add vli and ecc functions which are required for other Elliptic curve algorithms like ECDSA and ECIES. Patch #4 adds support for ECDSA. This has been validated for P192 and P256 elliptic curves. Patches #5 and #6 add ECDSA tests to validate ECDSA functionality and measure ECDSA performance. Changes in v2: * Added ecc_is_pub_key_valid() for public key validation * Use crypto_rng_get_bytes() to get random bytes * Add documentation in ecdsa.h for ECDSA keys and related APIs * Reorg ECDSA sign and verity tests to reuse code Nitin Kumbhar (6): crypto: ecc: separate out ecc and ecdh crypto: ecc: add vli and ecc ops crypto: ecc: export vli and ecc ops crypto: ecdsa: add ECDSA SW implementation crypto: testmgr: add ECDSA tests crypto: tcrypt: add ECDSA test modes crypto/Kconfig | 14 ++ crypto/Makefile | 8 +- crypto/ecc.c | 421 +++++++++++++++++++++++++++++++------------- crypto/ecc.h | 101 +++++++----- crypto/ecc_curve_defs.h | 51 +----- crypto/ecc_ecdh.h | 54 ++++++ crypto/ecdh.c | 4 +- crypto/ecdh_helper.c | 94 ++++++++++ crypto/ecdsa.c | 362 ++++++++++++++++++++++++++++++++++++++ crypto/ecdsa_helper.c | 116 +++++++++++++ crypto/tcrypt.c | 250 ++++++++++++++++++++++++++- crypto/tcrypt.h | 122 +++++++++++++ crypto/testmgr.c | 330 +++++++++++++++++++++++++++++++++++- crypto/testmgr.h | 140 +++++++++++++++ include/crypto/akcipher.h | 5 +- include/crypto/ecc.h | 24 +++ include/crypto/ecdh.h | 10 +- include/crypto/ecdsa.h | 81 +++++++++ 18 files changed, 1962 insertions(+), 225 deletions(-) create mode 100644 crypto/ecc_ecdh.h create mode 100644 crypto/ecdsa.c create mode 100644 crypto/ecdsa_helper.c create mode 100644 include/crypto/ecc.h create mode 100644 include/crypto/ecdsa.h -- 1.7.6.3
