What is the difference between FIPS 140-2 and FIPS 197 certification?

FIPS 197 certification looks at the hardware encryption algorithms used to protect the data. FIPS 140-2 is the next, more advanced level of certification. FIPS 140-2 includes a rigorous analysis of the product’s physical properties. So, with a FIPS 140-2 certified USB Flash Drive the tamper-proof design of the circuit board has been approved, as well as the data encryption.
