Demonstrating Trusted Blockchain IoT Device Based On TLS-PSK Secure Element
Pascal Urien · 2023
This demonstration presents an Internet of Things (IoT) device built around a secure element. According to the Blockchain IoT (BIoT) paradigm, it is able to generate Ethereum transactions of which data are sensor information or actuator states. All network communications are controlled by the secure element through the TLS pre-shared-key protocol. Specific requests are exported from secure element and unlock protected resources such as signing procedure. This avoids the misuse of the private key required for blockchain transaction generation.
