Abstract

An embodiment of a semiconductor package apparatus may include technology to generate a first output from a physically unclonable function (PUF) based on a challenge, modify the challenge based on the first output, and generate a response based on the modified challenge. Some embodiments may additionally or alternatively include technology to change a read sequence of the PUF based on an output of the PUF. Some embodiments may additionally or alternatively include technology to vary a latency of a linear feedback shift register based on an output from the PUF. Other embodiments are disclosed and claimed.
