Cryptographic module principles

So far, we have discussed cryptographic algorithms, algorithm inputs, uses, and other important aspects of applied cryptography. Familiarity with cryptographic algorithms is not enough, however. The proper implementation of cryptography in what are called cryptographic modules, though a topic not for the faint of heart, is needed for IoT security. Earlier in my (Van Duren) career, I had the opportunity not only to test many cryptographic devices, but also manage, as laboratory director, two of the largest NIST-accredited FIPS 140-2 cryptographic test laboratories. In this capacity, I had the opportunity to oversee and help validate literally hundreds of different device hardware and software implementations, smart ...
