FPGAs Vulnerable to Power Analysis Hacks?

By JDavis | 12/14/09 7:21 AM

As reported in a recent EDN blog post, FPGAs (field-programmable gate arrays) are being widely used in federal/defense applications (those requiring FIPS-140 certification) and their increased usage is sparking concerns about their cryptographic security. Of particular concern is possible FPGA vulnerability to hackers using power analysis -- examining a device's power dissipation -- to extract cryptographic keys.
