Achieving the National Intelligence Service's Cryptographic Module Verification (KCMVP) with 'T-Crypto' technology
High-volume data processing required, enhanced communication security, and response to hacking threats.

SK Telecom has taken the lead in enhancing customer information security by obtaining the first quantum cryptography-based encryption equipment certification in Korea.

SK Telecom announced on the 18th that it had obtained the National Intelligence Service Cryptographic Module Verification (KCMVP) for a transmission encryption module that satisfies the international standard for quantum cryptography key linkage.

The modules certified by SKT this time are two products that support data transmission speeds of 100 Gbps and 10 Gbps.

It will be installed in next-generation optical communication equipment (POTN) that handles high-capacity traffic, and will be supplied to communication networks of governments, local governments, the military, and civilians where information security is particularly important, thereby accelerating the practical application of quantum cryptography technology.

SKT, considering the risk that existing encryption systems could be disabled due to the advancement of quantum computing technology, has proactively developed and commercialized quantum cryptography technology that can overcome security threats.

'T-Crypto', which SKT applied for this certification, is a mutual authentication and encryption key exchange technology based on a mathematical algorithm and SKT's quantum key distribution (QKD)It features enhanced security through data encryption linked to .

"T Crypto" utilizes LEA (Lightweight Encryption Algorithm), a purely domestic encryption technology. LEA is an algorithm that reduces computational resources by up to 50% while maintaining the same level of security as existing technologies. Based on this, data traffic can be safely encrypted or decrypted on optical lines that transmit information at speeds of up to 100 Gbps.

Meanwhile, SKT has applied quantum cryptography technology to its 5G/LTE backbone network and actively utilized T Crypto technology in its services that require high-strength security, such as smart factories and healthcare.

SKT's Jong-Kwan Park, head of infrastructure technology, said, "The development of the T Crypto encryption technology, which recently received KCMVP certification, is the result of our continuous efforts to strengthen the security of SKT's 5G service," and added, "We will continue to strengthen technology development so that we can achieve the world's highest level of security."
