Subgroup Attack

cryptography is vulnerable to a Subgroup Attack. The vulnerability is due to missing validation of the point belonging to the expected prime-order subgroup of the curve, where an attacker can provide a public key point P from a small-order subgroup and this can lead to security issues in various...
