Extracting Secrets from FPGAs

"How would you ever extract a secret from that FPGA?" "Ah easy, we just look at the analog imprint from bias temperature instability effects on the underlying transistors." Hardware security is just insane. Pentimento: Data Remanence in Cloud FPGAs arxiv.org

A black-background screenshot presents a joke about extracting secrets from an FPGA by analyzing analog traces left by bias temperature instability in its transistors. The punchline is that hardware security is surprisingly difficult because physical effects can preserve information even after data is supposedly erased; the attached arXiv paper provides the technical reference.
