FACTOID #53: If you thought Antarctica was inhospitable, think again - its land area is only ninety-eight percent ice. Reassuringly, the other 2% is categorised as "barren rock".
Just like in RSA the security of the system relies on the difficulty of factoring very large numbers. 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 him to forge a signature for a single additional message.

In cryptography, GMR is a digital signaturealgorithm named after its inventors Shafti Goldwasser, Silvio Micali and Ron Rivest.
