Will Secure Elements Strengthen Crypto Wallets? Hardware Security Auditing
Byeongcheol Yoo evaluates hardware cryptocurrency wallets, analyzing whether Secure Elements (SE) effectively defend private keys against physical attacks.
Summary
Software vs. Hardware Cryptocurrency Wallets
While software wallets store private keys on internet-connected hosts vulnerable to malware, hardware wallets isolate cryptographic seed phrases within dedicated microcontroller silicon.
Architecture and Role of Secure Elements (SE)
Byeongcheol Yoo explains the security mechanisms of Common Criteria certified Secure Elements, designed to resist physical tampering and side-channel leakage.
Auditing Hardware Wallet Physical Attack Surfaces
Yoo examines vulnerability classes affecting hardware wallets—including supply chain interdiction, fault injection (voltage glitching), and bus sniffing.
Designing Resilient Hardware Cryptographic Storage
The author provides hardware manufacturers with secure chip selection guidelines and firmware attestation protocols.
