+Changes
+ * The ECP module, enabled by `MBEDTLS_ECP_C`, now depends on
+ `MBEDTLS_CTR_DRBG_C` or `MBEDTLS_HMAC_DRBG_C` for some side-channel
+ coutermeasures. If side channels are not a concern, this dependency can
+ be avoided by enabling the new option `MBEDTLS_ECP_NO_INTERNAL_RNG`.
+
+Security
+ * Fix side channel in mbedtls_ecp_check_pub_priv() and
+ mbedtls_pk_parse_key() / mbedtls_pk_parse_keyfile() (when loading a
+ private key that didn't include the uncompressed public key), as well as
+ mbedtls_ecp_mul() / mbedtls_ecp_mul_restartable() when called with a NULL
+ f_rng argument. An attacker with access to precise enough timing and
+ memory access information (typically an untrusted operating system
+ attacking a secure enclave) could fully recover the ECC private key.
+ Found and reported by Alejandro Cabrera Aldaya and Billy Brumley.

+ * Fix issue in Lucky 13 counter-measure that could make it ineffective when
+ hardware accelerators were used (using one of the MBEDTLS_SHAxxx_ALT
+ macros). This would cause the original Lucky 13 attack to be possible in
+ those configurations, allowing an active network attacker to recover

+ * When this option is disabled, mbedtls_ecp_mul() will make use of an
+ * internal RNG when called with a NULL \c f_rng argument, in order to protect

+ *
+ * This protection introduces a dependency of the ECP module on one of the

+ * attacks are outside your threat model), it might be desirable to get rid of
+ * that dependency.
+ *
+ * \warning Enabling this option makes some uses of ECP vulnerable to some
+ * side-channel attacks. Only enable it if you know that's not a problem for
+ * your use case.

+ * Uncomment this macro to disable some counter-measures in ECP.
