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 future-proof 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.
The company is closely following standards recommended by the National Institute of Standards and Technology (NIST)1 to defend against quantum computer attacks. 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 optimizing performance and minimizing 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 future-proof cloud data against quantum threats.
