    Tibor Jager, Jörg Schwenk, and Juraj Somorovsky, from Horst Görtz
    Institute for IT Security, published a paper in ESORICS 2015 where they
    describe an invalid curve attack in Bouncy Castle Crypto, a Java library
    for cryptography. An attacker is able to recover private Elliptic Curve
    keys from different applications, for example, TLS servers.
