According to a recent report, Bitcoin is susceptible to cryptographic attack.
The attack, which is dubbed “side channel analysis” utilizes a secret decryption key from data which is leaked from a specific cryptographic system.
“We illustrate the effectiveness of the attack by recovering the secret key with a very high probability using only a small number of signatures,” the researchers wrote. “After this, we are able to forge unlimited signatures under the hidden secret key. The results of this attack are not limited to ECDSA but have implications for many other cryptographic protocols implemented using OpenSSL for which the scalar multiplication is performed using a sliding window, and the scalar is intended to remain secret.”
