Whether a very simple product or a complex system, security is an important consideration today. By including a security component in a product’s design, one can experience multiple benefits. Security can prevent someone from copying or modifying firmware in a product; ultimately, strong security can prevent someone from cloning the finished product. That same security component can be used to authenticate the product for warranty repair and reduce fraudulent claims. In more complex systems, security is key to controlling access and protecting privacy. If attached to a network, establishing trust with other nodes and ensuring that downloads are genuine will require security to be a part of the system.
