SKT's Authentication Solution "Passkey" Achieves GS Certification Grade 1

Adoption in Core Internal Systems

Plans to Expand into the Enterprise Market

On May 12, SK Telecom announced that its authentication solution, "SK Telecom Passkey," has received the highest grade, Grade 1, in the GS (Good Software) certification from the Telecommunications Technology Association (TTA) of Korea.

The GS certification is a nationally recognized certification system that evaluates software for functional suitability, security, and reliability, based on ISO/IEC international standards.

"SK Telecom Passkey" is a next-generation authentication solution based on FIDO (Fast Identity Online) that allows users to log in more easily and securely by using biometric authentication methods such as fingerprint and facial recognition, or device unlock methods like PIN or pattern, instead of traditional password-based access.

Passkey operates on the principle of public key cryptography. When a user registers for a service for the first time, a pair of private and public keys is generated within the device. The private key is stored only in the secure area of the user's device and is never transmitted externally. The public key is registered on the service server and used for authentication.

During subsequent logins, when the server requests identity verification, authentication is completed by signing with the private key stored on the device and sending the signed response. Only the signature value is transmitted, rather than any password, ensuring that no key-related information is left on the network.

This solution is provided in the form of a Software Development Kit (SDK) that supports a variety of device environments, including Android and iOS.

With this certification, SKT plans to gradually introduce Passkey to its internal systems, aiming to establish a "passwordless work environment." After further verifying the technology's stability within the company, SKT intends to expand its application to external services.

Lee Jonghyun, Chief Information Security Officer (CISO) and Head of the Integrated Security Center at SKT, stated, "Achieving Grade 1 in the GS certification proves that SKT's technology, developed based on FIDO standards, meets the highest level of national certification criteria. Building on this, we will further strengthen our internal security framework and continue to create a safe authentication environment."
