| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Based on OpenSSL commit 875ba8b21ecc65ad9a6bdc66971e50 by Billy Brumley, Sohaib ul Hassan and Nicola Tuveri. ok beck jsing commit 875ba8b21ecc65ad9a6bdc66971e50461660fcbb Author: Sohaib ul Hassan <soh.19.hassan@gmail.com> Date: Sat Jun 16 17:07:40 2018 +0300 Implement coordinate blinding for EC_POINT This commit implements coordinate blinding, i.e., it randomizes the representative of an elliptic curve point in its equivalence class, for prime curves implemented through EC_GFp_simple_method, EC_GFp_mont_method, and EC_GFp_nist_method. This commit is derived from the patch https://marc.info/?l=openssl-dev&m=131194808413635 by Billy Brumley. Coordinate blinding is a generally useful side-channel countermeasure and is (mostly) free. The function itself takes a few field multiplicationss, but is usually only necessary at the beginning of a scalar multiplication (as implemented in the patch). When used this way, it makes the values that variables take (i.e., field elements in an algorithm state) unpredictable. For instance, this mitigates chosen EC point side-channel attacks for settings such as ECDH and EC private key decryption, for the aforementioned curves. For EC_METHODs using different coordinate representations this commit does nothing, but the corresponding coordinate blinding function can be easily added in the future to extend these changes to such curves.

* RFC 3394 section 2 states that we need at least two 64 bit blockstb2018-10-201-6/+6
| | | | | | | | | | | | | | for wrapping and, accordingly, three 64 bit blocks for unwrapping. That is: we need at least 16 bytes for wrapping and 24 bytes for unwrapping. This also matches the lower bounds that OpenSSL have in their CRYPTO_128_{un,}wrap() functions. In fact, if we pass an input with 'inlen < 8' to AES_unwrap_key(), this results in a segfault since then inlen -= 8 underflows. Found while playing with the Wycheproof keywrap test vectors. ok bcook
