April 29, 2025 09:20 ET  | Source: SEALSQ Geneva, Switzerland, April 29, 2025 (GLOBE NEWSWIRE) -- SEALSQ Corp (NASDAQ: LAES) ("SEALSQ" or "Company"), a company that focuses on developing and selling Semiconductors, PKI, and Post-Quantum technology hardware and software products, today highlighted how its quantum-resistant secure microcontrollers can strengthen the resilience of IoT connected devices and networks including electrical grids. The massive blackout that disrupted Spain and Portugal on April 28, 2025, which was triggered by extreme atmospheric conditions, underscores the urgent need for secure, reliable IoT solutions to safeguard critical infrastructure. By securing the IoT ecosystem, SEALSQ’s technology ensures that the data driving smart grids remains trustworthy, even under extreme environmental conditions or cyber threats. According to Spain’s grid operator, Red Eléctrica (REE), the blackout resulted from temperature-induced vibrations in high-voltage transmission lines (400kV), causing synchronization failures between Spain and France’s electrical systems. This cascade led to the loss of 15 gigawatts of power in seconds, affecting millions of customers. Such environmental disruptions, combined with growing cyber threats, highlight vulnerabilities in aging grid infrastructure. SEALSQ’s post-quantum secure microcontrollers address these challenges by securing IoT sensors and monitoring devices deployed across electrical networks. These chips, embedded in devices like substations and transmission line sensors, ensure the authenticity, integrity, and confidentiality of critical environmental and operational data, such as temperature, voltage, and oscillations. Equipped with quantum-resistant cryptographic algorithms, SEALSQ’s technology protects against next-generation cyberattacks, including those enabled by quantum computing, ensuring grid operators can trust real-time data for decision-making. “IoT sensors are transforming smart grids by enabling real-time monitoring and automated fault detection,” said Carlos Moreira, CEO of SEALSQ. “However, their effectiveness depends on secure data transmission. Our quantum-resistant microcontrollers safeguard these devices, empowering grid operators to detect anomalies like temperature swings or synchronization issues early and act before failures escalate.” By integrating SEALSQ’s secure microcontrollers, grid operators can: Ensure secure, tamper-proof data collection from IoT sensors monitoring environmental and grid parameters.Protect against cyberattacks that could manipulate or disrupt critical grid communications.Enable rapid, automated responses to anomalies, such as isolating faulty segments to prevent cascading failures.Support the integration of renewable energy sources into smart grids by securing data at interconnection points. As smart grids evolve to incorporate renewable energy and advanced analytics, SEALSQ’s secure IoT architecture enhances reliability, protects against cyber threats, and supports system reconfiguration to minimize power losses. This is critical for maintaining voltage stability and operational efficiency in volatile conditions. SEALSQ remains committed to protecting global critical infrastructure with cutting-edge, quantum-resistant solutions that address the challenges of an increasingly connected and unpredictable world.
