Class PublicKeyParameterValidationUtil

  • public class PublicKeyParameterValidationUtil
extends java.lang.Object
    Utility class to verify keys against Key Overwriting (KO) attacks. This class of attacks is only possible if the attacker has access to the (encrypted) secret key material. To execute the attack, they would modify the unauthenticated parameters of the users public key. Using the modified public key in combination with the unmodified secret key material can then lead to the extraction of secret key parameters via weakly crafted messages.
