Abstract
Removing protections on a session-key protected design include receiving a double encrypted vendor private key and an encrypted session key. The double encrypted vendor private key is decrypted into a single encrypted vendor-private key using a user private key, and the single encrypted vendor-private key is decrypted into a vendor private key using a vendor pass phrase. The encrypted session key is decrypted into a session key using the vendor private key, and the session-key protected design is decrypted into a plain design using the session key.
