Abstract
A method and system for maintaining the security of design information is disclosed. The method includes generating an encrypted IP core by encrypting an IP core using a public key, downloading the encrypted IP core to a programmable logic device (PLD), and recovering the IP core by decrypting the encrypted IP core using a private key. The private key is associated with the PLD, and the public key and the private key correspond to one another. The method may further include the PLD receiving authorization information corresponding to the IP core and comparing local authorization information stored at the PLD with the authorization information.
