Hardware Integration

PQC-IIoT is designed to run securely on general-purpose hardware but supports enhanced security through dedicated hardware integration.

Supported Hardware

• TPM 2.0: Using the tss-esapi crate standard.
• Secure Elements (SE): Interface for I2C/SPI connected secure elements (e.g., ATECC608, SE050).
• HSM: PKCS#11 support (Planned).

Integration Pattern

The library uses the SecurityProvider trait to abstract hardware details.

#![allow(unused)]
fn main() {
// Your custom provider implementation
struct TpmProvider { ... }

impl SecurityProvider for TpmProvider {
    fn sign(&self, msg: &[u8]) -> Result<Vec<u8>> {
        // Send command to TPM to sign
        // Private key never leaves TPM
    }
}
}
