Detail

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.
