We are now in the business of connecting everything to everything. And with this, the Internet of Things (IoT) is born. Once this total connectivity is accomplished, the collective effort this brings lets us start the next string of new and exciting systems. This results in massive amounts of data that must be trusted and processed.

But, as they say: "buyer beware." This is all good, but total connectivity opens the opportunity for unintentional or malicious data corruption and contamination to occur. Cryptographic methods can be applied to resolve these vulnerabilities. A decision that system designers face is deciding between software-based or hardware-based security solutions. Both technologies combat unauthorized access or modification to data; however, their differing features bear further examination before making the final selection.
