We do a lot of things on our smartphones. We take photos, chat with friends, send emails, shop, and perform financial transactions. The latter is particularly sensitive, which is why having strong security is essential. Thankfully, this is something Samsung considered when developing its Galaxy S25 smartphones, where its new handsets come with post-quantum cryptography.
Super secure
The Galaxy S25 announcement focused heavily on the performance of the handsets. Samsung also talked a lot about the AI features available on the phone. However, if you only skimmed through the announcement, you might have missed the part where Samsung revealed their new phones’ security features.
These security features include the Knox Vault. The Knox Vault keeps your personalized AI data private. AI processing is one of the features on the phone, thanks to the use of the powerful Qualcomm Snapdragon 8 Elite chipset. This is great news for those concerned about their privacy when AI processing requests are sent to a remote server.
However, even on-device, the data needs to be stored securely. This is where the Knox Vault comes in. Other security features include a new Knox Matrix dashboard, new Maximum Restriction settings, and enhanced Theft Protection.
However, what caught our attention was a security feature of the Galaxy S25 series which comes in the form of post-quantum cryptography.
What is post-quantum cryptography, and why it matters
The data stored on our phones are encrypted. It’s protected using the PIN code we use to unlock our phones or biometrics like fingerprint or facial recognition. Technically, this makes it pretty secure. However, as smartphone security becomes more advanced, so do hacking methods.
This is where post-quantum cryptography comes in. It helps protect devices, like the Galaxy S25, from cryptanalytic attacks made by a quantum computer. Quantum computers are extremely powerful computers that can break commonly used public key algorithms. Currently, this isn’t a problem that users need to be too worried about.
Quantum computers do exist, but they’re not available to the general public. This means that a random attacker is unlikely to hack your device. However, it doesn’t mean that we should take security for granted. It is possible that one day these threats will be very real. At the very least, Samsung is futureproofing its Galaxy S25 phones with post-quantum cryptography technology.
