Samsung and South Korean operator SK Telecom have announced the Galaxy Quantum 2, the second Samsung phone with built-in quantum encryption technology for added security. It is the sequel to last year’s Galaxy A Quantum.
Quantum 2 includes a chip developed by a company called Quantum ID, which claims to be the world’s smallest quantum random number generator (QRNG) at 2.5 mm square. It works by capturing random noise with an LED and a CMOS image sensor. According to SK Telecom, the QRNG chip “enables smartphone owners to use services that require security in a more secure and secure way by generating truly random, unpredictable and patternless numbers”.
Hacking RNG quantum cryptography is extremely difficult without widespread physical access to a specific device. The benefits will seem very suitable for the average customer, but the QRNG chip automatically works with applications that use the Android Keystore APIs, making the technology more affordable for developers. SK Telecom promotes local compliance with companies like Shinhan Bank and Standard Chartered Bank Korea, as well as its own services such as T World. The operator says it will work with more services in the future, including credit cards for Samsung.
The phone itself has reasonably high specifications, close to what you would find in a high-end flagship phone a year or two ago. It has a Qualcomm Snapdragon 855 Plus processor, a 64MP camera, and a 6.7 inch 120Hz OLED screen.
Galaxy Quantum 2 is only confirmed to be launched in South Korea at this time. It will go on sale on April 23rd.
