-Subject: [PATCH] Add blinding to an ECDSA signature
-
-Keegan Ryan (NCC Group) has demonstrated a side channel attack on an
-ECDSA signature operation. During signing the signer calculates:
-
-s:= k^-1 * (m + r * priv_key) mod order
-
-The addition operation above provides a sufficient signal for a
-flush+reload attack to derive the private key given sufficient signature
-operations.
-
-As a mitigation (based on a suggestion from Keegan) we add blinding to
-the operation so that:
-
-s := k^-1 * blind^-1 (blind * m + blind * r * priv_key) mod order
-
-Since this attack is a localhost side channel only no CVE is assigned.
