. As with RSA the security of the system is related to the difficulty of factoring very large numbers. But, in contrast to RSA, GMR is secure against ''adaptive chosen-message attacks'' — even when an attacker receives signatures for messages of his choice, this does not allow them to forge a signature for a single additional message.
