Today SK Telecom presents the Galaxy A Quantum, the world’s first 5G smartphone equipped with a quantum random number generator (QRNG) in cooperation with Samsung Electronics and ID Quantique.

The company will open pre-order for the Galaxy A Quantum from May 15 to 21, 2020 and officially launch the device on May 22, 2020 in Korea.
 
The Galaxy A Quantum is equipped with the world’s smallest QRNG IC measuring 2.5mm by 2.5mm. This QRNG IC allows smartphone holders to use selected services in a safe and secure manner by generating true random numbers that cannot be hacked.

Integrated with quantum enhanced cryptography, the Galaxy A Quantum will allow customers to experience advanced security through two-factor authentication (2FA) for T-ID*; biometric authentication-based payment for SK Pay** app; and a blockchain-based mobile e-certification service named Initial.

Users of the Galaxy A Quantum will go through two-factor authentication (2FA) – i.e. ID login and quantum one-time password (OTP) authentication – when they log in with their T-IDs. By adding OTP authentication as an extra layer of protection, the QRNG-powered smartphone ensures strong protection for users’ online accounts.
 
2FA for T-ID is expected to be well utilized as T-ID login is applied to SK Telecom’s 28 services including 11st (online marketplace), T Map (mobile navigation), Wavve (OTT platform), Flo (music streaming), T Membership (subscriber membership) and Nugu (AI platform/speaker).
 
Customers will also benefit from advanced protection while making payments via the SK Pay app at offline affiliate stores such as convenience stores and restaurants. Going forward, SK Telecom plans to expand the feature to the mobile apps of SK Pay affiliate stores.
 
By choosing ‘SKT 5GX Quantum’ when storing their biometric authentication information in the SK Pay app, customers will receive an alert that says “SK Pay is being protected by SKT 5GX Quantum” at the top of the screen, assuring that they are making payments in a safe and secure manner.

 Moreover, with the application of quantum security, Initial will offer an added layer of security by creating an encrypted ‘quantum wallet’ when users store their personal certificates (e.g. pass, license, transcript, graduation certificate, insurance claim documents, etc.) in Initial.

With the aim to constantly develop and expand services based on quantum security, SK Telecom plans to open application programming interfaces (APIs) to developers through SK Open API Portal and support the development of relevant technologies to expand the ecosystem.
 
Meanwhile, SK Telecom has been making investments in quantum security technologies since 2011, actively developing quantum key distribution (QKD) and quantum random number generators (QRNGs).
 
Last year, SK Telecom and ID Quantique have been awarded quantum communication network building projects in the U.S. and Europe (EU), and applied QRNG to SK Telecom’s 5G authentication center (AuC) for the first time in the world. Going forward, SK Telecom will expand its footprint in the quantum security business by integrating QRNGs to more devices and networks.
