Abstract
An integrated circuit (IC) protection circuit can include a reconfigurable block that receives a seed value from a tamper-proof memory and generates a dynamic key; an authentication block that receives the dynamic key from the reconfigurable block and taint bits from a scan chain to generate an authentication signature; and an encryptor that encrypts a test pattern response on the scan chain if a mismatch is found between the authentication signature and a test pattern embedded signature.
