Practical Internet of Things Security - Second Edition

Summary

In this chapter, we touched on the enormously large and complex world of applied cryptography, cryptographic modules, key management, cryptographic application in IoT protocols, and a possible future of the cryptographic enablement of distributed IoT trust in the form of blockchain technology.

Perhaps the most important message in this chapter is to take cryptography and its methods of implementation seriously. Many IoT devices and service companies simply do not come from a heritage of building secure cryptographic systems and it is unwise to consider a vendor's hyper-marketed claims that their 256-bit AES is secure. There are just too many ways to thwart cryptography if not properly implemented.

In Chapter 7, Identity and Access ...
