Samsung Electronics has been working on a new form of cutting-edge mobile security, starting from the Galaxy S25 series. Known as post-quantum cryptography (PQC), the technology uses advanced algorithms to with a goal to protect against the potential risks that quantum computing poses to traditional encryption methods.

Samsung Newsroom explored the future of digital security to understand why Samsung is already taking these protective measures.

Eyes on the Horizon

Quantum computing represents one of the most transformative fields in modern technology, offering unparalleled problem-solving capabilities. By harnessing the power of quantum computers, complex challenges can be solved exponentially faster than with traditional computing — unlocking breakthroughs in numerous industries from medicine to logistics. For instance, quantum algorithms could streamline supply chains or improve punctuality in transportation systems.

However, this immense computational power comes with risks. Because quantum algorithms have the potential to break certain encryption methods used to safeguard today’s data, addressing this vulnerability is critical to ensuring data protection in the future.

While quantum computing is not expected to reach full-scale implementation immediately, early action is essential to protection against “harvest now, decrypt later” threats — where attackers collect data now to decrypt it with future quantum capabilities.

Redefining Standards of Defense

Samsung has been working on PQC to ensure encrypted data remains secure in a quantum-powered world.

For example, the ML-KEM (Module-Lattice-Based Key-Encapsulation Mechanism) algorithm employs lattice-based mathematics — complex multidimensional structures that make encryption keys exceptionally difficult to solve, even for quantum computers. Ideal for secure communication between connected devices, the algorithm provides robust security while optimising performance and minimising data exchange.

NIST’s PQC standards secure a wide range of electronic information from confidential emails to e-commerce transactions. For Samsung, they are a way to protect cloud data against quantum threats.

Samsung’s Strategic Approach

Committed to protecting user data as technologies such as quantum computing evolve, Samsung is introducing Post-Quantum Enhanced Data Protection (EDP) to Samsung Knox Matrix — the company’s leading protection for connected device ecosystems.

Samsung’s EDP feature currently provides end-to-end encryption for user data when backing up, restoring or syncing personal information through Samsung Cloud.

With the integration of PQC technology to Knox Matrix, another layer of protection has been added — setting a new standard for cloud security on mobile devices. Knox Matrix’s cross-device compatibility will ensure seamless quantum-safe protection for Samsung Cloud backups and synced data across smartphones, TVs and digital appliances.

This feature is available on the new Galaxy S25 series as the first Samsung device operating on One UI 7, giving Galaxy users enhanced protection.

Samsung Leading a Secure Future

In an ever-evolving digital landscape, preparing for potential threats is not an option but a necessity. As quantum computing looms on the horizon, the need to protect data has become increasingly clear.

Moving forward, Samsung will continue to pioneer the mobile security industry and create a future where users can enjoy a connected world with added peace of mind.

Samsung Electronics Co., Ltd. today announced that its proprietary cryptography module, Samsung CryptoCore[1], has earned the prestigious FIPS 140-3 certification[2] from the National Institute of Standards and Technology (NIST). This certification underscores Samsung’s commitment as an industry-leader in security for Smart TV users.

“As home entertainment systems become more connected, it becomes critical for technology companies to safeguard the data that enables the seamless connectivity enjoyed by so many,” said Yongjae Kim, Executive Vice President and Head of the R&D Team, Visual Display Business at Samsung Electronics. “By integrating the FIPS 140-3-certified CryptoCore into our Smart TVs, Samsung is taking our commitment to secure home entertainment a step further and ensuring that our users can experience the value of our products.”

Beginning in 2025, Samsung CryptoCore will be fully integrated into Tizen OS[3], Samsung’s Smart TV operating system, enhancing the security of key products such as TVs, monitors and digital signage. With Samsung CryptoCore embedded in Tizen OS, data linked to Samsung accounts will be securely encrypted, SmartThings authentication information will be safeguarded from the risks of external hacking threats.

Since 2015, Samsung has equipped its Smart TVs with Samsung Knox[4], a security platform that has earned Common Criteria (CC) certification[5] for 10 consecutive years. But with its newly acquired FIPS 140-3 certification, Samsung has strengthened its defenses against hacking and external threats even further, proactively protecting data with advanced encryption technology.

Recognised by governments in 10 countries[6], the FIPS 140-3 certification requires comprehensive testing of cryptographic modules to ensure their security, integrity, and reliability. For users, this means Samsung Smart TVs offer a high level of protection against external threats, allowing them to enjoy their content, connect smart devices, and engage with IoT services securely.
