Cryptographic key management fundamentals

Now that we have addressed basic cryptography and cryptographic modules, it is necessary to delve into the topic of cryptographic key management. Cryptographic modules can be considered cryptographically secured islands in larger systems, each module containing cryptographic algorithms, keys, and other assets needed to protect sensitive data. Deploying cryptographic modules securely, however, frequently requires cryptographic key management. Planning key management for an embedded device and/or full scale IoT enterprise is essential to securing and rolling out IoT systems. This requires organizations to normalize the types of cryptographic material within their IoT devices and ensure they work across systems ...
