Why Hardware Privacy Matters
Why Hardware Privacy Matters
Hardware-based privacy provides fundamental security advantages that software-only solutions cannot match. This document explains why hardware privacy is essential for protecting cryptographic keys and enabling secure offline transactions.
The Software Security Problem
Software Vulnerabilities
Attack Surface:
Software is vulnerable to malware
Keys stored in software are accessible
Operating system vulnerabilities
Application vulnerabilities
Network attacks
Limitations:
Cannot prevent software attacks
Keys can be extracted
Memory can be read
No physical protection
Why Software Alone Isn't Enough
Key Extraction:
Malware can steal keys
Memory can be dumped
Keys can be copied
No hardware protection
Network Exposure:
Keys transmitted over network
Network attacks possible
Man-in-the-middle attacks
Key interception
