Side-Channel Leakage Shield
Electromagnetic & Power Trace Mitigation
Hardware and software countermeasures that eliminate subtle power consumption and electromagnetic radiation leaks used to steal crypto keys from mobile chips.
Technical Explanation
When a microchip executes cryptographic calculations, slight fluctuations in its electrical power draw and radiated electromagnetic emissions leak information about the private keys (Differential Power Analysis - DPA). The Side-Channel Leakage Shield incorporates constant-time cryptographic assembly routines, random algorithmic masking (blinding), and internal noise-injection circuits on silicon, making it impossible for physical attackers with oscilloscopes to steal keys.
Key Functions
- Constant-time cryptographic algorithmic execution eliminating timing side-channel leaks
- Randomized algorithmic masking (blinding) preventing Differential Power Analysis (DPA)
- On-chip hardware noise injection scrambling electromagnetic emissions from crypto dies
- Protecting mobile iSIMs and base station hardware from physical laboratory probing attacks
- Compliance with NIST FIPS 140-3 Level 4 physical security standards
