ROHNP: Key Extraction Side Channel in Multiple Crypto Libraries

Libgcrypt before 1.7.10 and 1.8.x before 1.8.3 allows a memory-cache side-channel attack on ECDSA signatures that can be mitigated through the use of blinding during the signing process in the gcryeccecdsasign function in cipher/ecc-ecdsa.c, aka the Return Of the Hidden Number Problem or ROHNP. T...
