This is the second device the manufacturer uses this type of encryption technology.
Samsung once again cooperated with South Korean telecom operator SK Telecom to launch its smart phone with a second security chip based on quantum technology. In Galaxy Quantum 2, the height of the company called ID Quantique is 2.5mm2 pcs It also has an area chip that randomly generates numbers with the help of LED lights and CMOS sensors.
The actual randomness or entropy of randomly generated numbers is the key to cryptography: if the hardware and software responsible for generating numbers behave in a predictable manner, or the signals they use as a starting point can be calculated, the encrypted information can be decrypted by guessing. In Samsung’s mobile phones, this is certainly no problem. The special chip has such a large randomness, so its output must not be used as an attack surface.
The benefit of this chip to ordinary customers is negligible. It provides random numbers for applications that use the Android factory KeyStore programming interface. Therefore, there is no doubt about the security of the encryption keys and passwords they generate. According to SK Telecom, in addition to some of its own services, local bank applications can also directly obtain random numbers from them for operation.
The more eye-catching features of the Samsung Galaxy Quantum 2 include a 6.7-inch and 1440 x 3200 pixel display, a 64 + 12 + 5 MP rear camera system, a 5G compatible Qualcomm Snapdragon 855+ system chip, 6 GB RAM and 128 GB storage. The phone will be launched in South Korea on April 23 at a price of HUF 188,000.
