With smartphones becoming an increasingly important part of our lives, security systems have become increasingly important. Recently, we reported a security flaw in Samsung’s Secure Folder. Although they have yet to resolve that problem, they have been working on an important project: a hardware post-quantum cryptography chip.
S3SSE2A is a new chip developed by Samsung System LSI (also responsible for Exynos) that addresses the threat of quantum computers.
Once quantum computing becomes commercially available after 2030, existing security systems will be vulnerable to it. These powerful machines can easily decrypt public-key cryptography, so traditional security measures could suddenly become obsolete. Most of you are probably aware of this. The fact that Samsung is investing time and energy into futureproofing its upcoming Galaxy devices is a good sign.
Samsung claimed as early as 2028 that its S3SSE2A chip can protect against quantum computing risks. The question is, which phones will actually benefit from this development? The announcement didn’t reveal much.
Samsung announced earlier this year that the Galaxy S25 series devices will feature PQC capabilities thanks to the Snapdragon 8 Elite chip.
Due to the association between the S3SSE2A chip and Samsung’s System LSI (which is different from the Snapdragon 8 Elite), future Galaxy flagships will be positioned as the most secure devices ever built. Samsung could also integrate this chip into its flagship Exynos chips, such as the Exynos 2600, and use them in the future S and Z series devices.
How it integrates with Samsung’s existing security features, such as Secure Folder, is still unclear.
