Asymmetric Encryption Engine

In addition to the essential symmetric encryption engines like AES for IoT, we also provide computationally more intensive asymmetric encryption algorithms ECDSA. This greatly alleviates the computational burden on the CPU and improves encryption and decryption speeds

Secure Boot

Based on asymmetric encryption and digital signature mechanisms, it verifies public key hashes and firmware signatures. This process can prevent tampering and rollback attacks, ensuring that the device only runs trusted firmware

Flash OTF Decryption

Supports both embedded and external Flash, with independent key encryption for multiple firmware. When the CPU executes encrypted firmware, it is decrypted in real-time by hardware, with nearly imperceptible performance impact. Supports unique encryption for each device, preventing injection and cloning attacks

OTP Secure Storage

Physical-level anti-extraction, key area locked for access only by the security engine, tamper-resistant and read-proof. Supports independent secure zones and CRC verification

True Random Number Generator (TRNG)

Generates high-security random numbers based on physical entropy sources. Certified by NIST for randomness. Provides unpredictability to the system, resistant to prediction attacks

HUK Derivation Mechanism

Hardware Unique Key (HUK) with physical isolation protection, unreadable and unclonable, used for secure derivation of application keys

Authenticated Debug Access

Strict control over debug interface access through authentication mechanisms. Supports authorized access and permanent closure, eliminating physical debug attacks. Meets security management requirements at different stages of the product lifecycle, effectively enhancing overall security

Security Certifications Support

We offer support for multiple security certifications. By providing these advanced security features and certification support, we aim to assist our customers in efficiently meeting various market entry requirements, ensuring the security and competitiveness of their products. Most of our chips are capable of achieving PSA Certified Level 2 and Level 3, with some chips already having completed PSA Certified Level 2 certification.
