Hardware Root of Trust

Technical Explanation

The foundation of all cellular security is the Hardware Root of Trust (HRoT)—traditionally the physical SIM card or embedded SIM (eUICC). In 6G, the integrated SIM (iSIM) is embedded directly into the main mobile processor die inside a tamper-proof secure enclave. The 6G HRoT features physical side-channel defenses, quantum-random number generators, and hardware accelerators for post-quantum algorithms, ensuring master keys cannot be extracted even with physical electron microscope probing.

Key Functions

• Tamper-resistant physical silicon enclave storing master subscriber authentication keys
• Hardware-accelerated execution of post-quantum cryptographic algorithms (ML-KEM/ML-DSA)
• Integrated SIM (iSIM) embedded directly onto the primary application processor die
• Physical side-channel resistance against differential power analysis (DPA) and laser fault injection
• Cryptographic measurement engine providing hardware-level remote attestation reports
