Abstract
An embodiment of the present invention provides a method and circuit for secure definition and integration of a core into a circuit design without exposing the core. In one embodiment, a core development package is obtained. The core development package includes an encrypted core and a decryption key of the encrypted core. The decryption key is encrypted with an asymmetric cipher. The encrypted core is transmitted from the design tool to a trusted platform module. The decryption key is decrypted with a private key of the asymmetric cipher. The encrypted core is decrypted within the trusted platform module. One or more design tool operations are performed using the decrypted core.
