Popis:	We extend the Flush+Reload side-channel attack of Benger et al. to extract a significantly larger number of bits of information per observed signature when using OpenSSL. This means that by observing only 25 signatures, we can recover secret keys of the secp256k1 curve, used in the Bitcoin protocol, with a probability greater than 50 percent. This is an order of magnitude improvement over the previously best known result.
