Figure 1 Trusted Platform Architecture with BIT
All devices across the IoT or embedded device ecosystems need to benefit from security to create a protected, trusted digital ecosystem. Where space, resources and costs are a barrier to implementing security protocols, the Block Integrated Trust (BIT) specification provides security no matter the size or budget of an IoT device.
The Block Integrated Trust (BIT) specification gives small devices the basic security capabilities of identity, measurement storage, and measurement reporting to attest to the health and trustworthiness of a device in an affordable way.
BIT is an isolated, lightweight hardware root of trust which can be integrated into all types of device designs including IoT devices, embedded devices, automotive vehicles, satellites, mobile phones as well as smart home devices and more.
The full Block Integrated Trust (BIT) Library specification helps to provide guidance on implementing the security protocols. To find out whether the MARS specification can be applied to a specific IoT or embedded device, the BIT Use Case and Considerations document is a helpful start.
