Practical Internet of Things Security - Second Edition

Types and uses of cryptographic primitives in the IoT

When most people think about cryptography, encryption invariably comes to mind. They understand that data is scrambled, so to speak, so that unauthorized parties cannot decrypt and interpret it. Real-world cryptography is composed of a number of other primitives, however, each partially or fully satisfying one of the previous IA objectives. Securely implementing and combining cryptographic primitives together to achieve a larger, more complex security objective should only be performed or overseen by security professionals well versed in applied cryptography and protocol design. Even the most minor error can prevent the security objective(s) from being fulfilled and result in costly vulnerabilities. ...
