ABSTRACT:
Encryption-based design obfuscation for an integrated circuit includes creating multiple functional circuit paths for an integrated circuit design and selecting among the multiple functional circuit paths during scan testing. Encrypting selection data corresponding to an intended function of the integrated circuit design avoids revealing the intended function as a result of the scan testing.
