Abstract
A method for exporting sensitive information an integrated circuit, the method comprising: fabricating an integrated circuit, the integrated circuit having a register-transfer level 'RTL' key fabricated in the integrated circuit, wherein the RTL key is a pre-determined cryptographic key; signing the sensitive information using the RTL key using a signature; and exporting the signed sensitive information and the signature for validation.
