During the presentation I will start by exploring low-level attacks to obtain secret keys:

•  Examining the Meltdown and Spectre attacks, which exploit hardware architectural features,
•  Understanding Side Channel Attacks on AES based on chip power consumption,
•  Analyzing example of poor key management and quality in WEP WiFi networks.

After that, I will explain how to secure cryptography keys by:

• proper generation (entropy and random number generator)
• safe exchange (Diffie-Helman and Quantum key approach)
• proper distribution (centralized vs distributed -> PKI vs blockchain approach)
• secure storage (in embedded devices, servers, hardware wallets)

Finally, I will provide an example of an IoT device to illustrate how the above features are demonstrated in real-world application.
