IoT and Edge Computing for Architects - Second Edition

Overview of this book

Industries are embracing IoT technologies to improve operational expenses, product life, and people's well-being. An architectural guide is needed if you want to traverse the spectrum of technologies needed to build a successful IoT system, whether that's a single device or millions of IoT devices. IoT and Edge Computing for Architects, Second Edition encompasses the entire spectrum of IoT solutions, from IoT sensors to the cloud. It examines modern sensor systems, focusing on their power and functionality. It also looks at communication theory, paying close attention to near-range PAN, including the new Bluetooth® 5.0 specification and mesh networks. Then, the book explores IP-based communication in LAN and WAN, including 802.11ah, 5G LTE cellular, Sigfox, and LoRaWAN. It also explains edge computing, routing and gateways, and their role in fog computing, as well as the messaging protocols of MQTT 5.0 and CoAP. With the data now in internet form, you'll get an understanding of cloud and fog architectures, including the OpenFog standards. The book wraps up the analytics portion with the application of statistical analysis, complex event processing, and deep learning models. The book then concludes by providing a holistic view of IoT security, cryptography, and shell security in addition to software-defined perimeters and blockchains.

Encryption and secrecy are absolute requirements of IoT deployments. They are used for securing communication, protecting firmware, and authentication. Regarding encryption, there are generally three forms to consider:

  • Symmetric key encryption: Encryption and decryption keys are identical. RC5, DES, 3DES, and AES are all forms of symmetric key encryption.
  • Public key encryption: The encryption key is published publicly for anyone to use and encrypt data. Only the receiving party has a private key used to decrypt the message. This is also known as asymmetric encryption. Asymmetric cryptography manages data secrecy, authenticates participants, and forces non-repudiation. Well-known Internet encryption and message protocols such as elliptic curve , PGP, RSA, TLS, and S/MIME are considered public keys.
  • Cryptographic hash: This maps data of an arbitrary size to a bit string (called the digest). This hash function is designed to be "one...
