- **Caution**: 
- **Caution**: 

### Q: What makes Secure Memory tamper-resistant?
**A**: Secure Memory uses specialized tamper-resistant packaging and detection circuits that trigger data erasure if physical or environmental tampering is detected, protecting cryptographic keys from unauthorized access.

### Q: How does Secure Memory integrate with Cryptographic Verifier systems?
**A**: It connects directly to the system's security processor via dedicated interfaces, providing isolated, encrypted storage for keys and certificates while maintaining high-speed access for verification operations.

### Q: What types of sensitive data can Secure Memory store?
**A**: It's designed specifically for cryptographic keys (RSA, ECC), digital certificates, authentication tokens, and other critical security parameters that require hardware-level protection against extraction or compromise.
