Ledger Hardware Security Architecture Audit
Verifying Secure Element (SE) chip technology, "What You See Is What You Sign" protocols, and the Donjon proactive security team.
01. Secure Screen Technology
Our audit highlights Ledger's unique Secure Screen architecture. Unlike competitors (Trezor, Jade) which use standard microcontrollers to drive their screens, Ledger's display is driven directly by the Secure Element.
"What You See Is What You Sign" (WYSIWYS)
This design ensures that transaction details are 100% tamper-proof. It eliminates "man-in-the-middle" attacks where malware on a computer or phone could alter the recipient address shown on screen.
02. Secure Element (SE) Implementation
Ledger hardware utilizes the ST33J2M0 (for Nano X) and similar CC EAL5+ certified Secure Element chips. These are the same chips trusted to secure passports and credit cards globally. Over 10 years of innovation and 8 million+ devices sold have resulted in zero successful hacks of the Secure Element.
