Chapter 5. Cryptographic Fundamentals for IoT Security Engineering

This chapter is directed squarely at IoT implementers, those developing IoT devices (consumer or industrial) or integrating IoT communications into their enterprises. It provides readers a background on establishing cryptographic security for their IoT implementations and deployments. While most of this book is devoted to practical application and guidance, this section diverges a bit to delve into deeper background topics associated with applied cryptography and cryptographic implementations. Some security practitioners may find this information common sense, but given the myriad cryptographic implementation errors and deployment insecurities even security-aware tech companies still deploy today, we decided this background was needed. The risks are growing worse, evidenced by the fact that many industries historically unfamiliar with security (for example, home appliance vendors) continue to network-connect and...
