Teaser text

Quadseal is a mitigation technique to stop attackers from obtaining secret keys from block ciphers. Where a conventional encrypting device is accessible it is possible to obtain the secret key in less than 10 minutes. With Quadseal the attacker is stymied, making communications channels and other protected items far safer.
