Building Comprehensive IoT Security from the Ground Up

True security must be embedded at the design phase, ensuring compliance with international security standards across system architecture, IC design, device manufacturing, and operational management. With a complete Root of Trust, key management, certificate management, and IoT security services, we ensure that devices meet the highest security standards throughout their design, production, deployment, and operation.

CHANGING IoT Security Solutions: Five Core Measures for a Secure Ecosystem

• Device Identity Authentication – Assigns a unique digital certificate to each IoT device, ensuring device authenticity and preventing spoofing attacks.
• Hardware-Based Key Protection – Utilizes secure chips (e.g., TPM) to store private keys within hardware, enhancing resistance against attacks.
• Firmware & Software Signature Verification – Rigorously validates the digital signatures of software and firmware updates, preventing unauthorized modifications and malicious attacks.
• Dedicated Root of Trust Architecture – Establishes an exclusive Root of Trust for enterprises and organizations, ensuring secure communication and data integrity.
• Certificate & Key Lifecycle Management – Manages the security and compliance of keys and certificates using a KMS (Key Management System) and Certificate Management System, improving operational efficiency.

Our solutions comply with FIPS 140-3, IEC 62443, ISO 21434, and IEC 61850 international security standards. By integrating cybersecurity considerations into product design and manufacturing, we meet market demands and regulatory requirements, reducing risks and enhancing brand reputation.

Trust and security begin at the product design stage, forming the foundation of IoT devices and ecosystems. With CHANGING, businesses can ensure data and device security, gaining a competitive edge in the global market!
