In an era where cybersecurity has become a core focus of global industrial development, the MIRDC once again demonstrates Taiwan's innovation strength in information security. Its self-developed "Featureless-Secure Encryption System for IoT (FSESI)" has been honored with the Bronze Award at the 2025 Edison Awards for Innovation. The technology overcomes long-standing limitations of chaotic encryption, offering a revolutionary solution for secure data transmission across IoT and international digital infrastructure.

Chaotic encryption, known for its high randomness and theoretical unbreakability, has long been viewed as a promising approach to data security. However, its real-world application has been hindered by sensitive parameter dependencies, complex key management, high computational costs, and data length constraints. With FSESI, MIRDC has addressed these challenges by creating a next-generation encryption system featuring untraceable, high-entropy keys, a lightweight algorithm, and real-time synchronized encryption and decryption. This dramatically enhances both the practicality and security of chaotic encryption.

At the core of FSESI is the use of multiple dynamically selected chaotic systems to generate keys that closely approximate true randomness. A specially designed sliding synchronization algorithm enables the rapid convergence of encryption and decryption systems, instantly generating identical key streams on both ends without requiring key transmission. This eliminates one of the most vulnerable points in traditional encryption: the key exchange process.

Technically, FSESI also discretizes the continuous differential equations of chaotic systems and applies carefully selected parameters, reducing computational load by approximately 60%. This significantly lowers CPU/GPU resource consumption, enabling high-performance, low-power encryption protection. Meanwhile, encrypted data undergoes dynamic random topic transformation, making it completely unidentifiable during transmission and highly resistant to data interception and reverse engineering.

FSESI is particularly suitable for environments requiring secure, synchronized communication across multiple devices and domains-such as IoT systems, blockchain nodes, drones, intelligent transportation, and medical data transmission. The system has already passed real-world validation through field testing with metal product manufacturers and equipment suppliers. It has also been successfully licensed to automation service integrators, helping manufacturing sectors strengthen the cybersecurity of their operational technology (OT) systems.

More than just an evolution in encryption technology, FSESI represents a paradigm shift in cybersecurity-from identity-based defense to stealth-based protection. With its dynamic, featureless, and decentralized security architecture, FSESI offers robust defense against modern threats while preserving data privacy across digital ecosystems. Looking ahead, the system will continue expanding into global applications in manufacturing, healthcare, and smart cities, supporting industries in achieving higher levels of digital trust and security resilience.
