DigiCert, a company specialising in digital trust, said on Tuesday it has presented an integrated security strategy centred on its intelligent trust platform, DigiCert ONE.

The company said concerns are being raised that widely used RSA and ECC-based public key cryptography algorithms could see security significantly weakened if large-scale quantum computers are commercialised.

To prepare, the National Institute of Standards and Technology has approved post-quantum cryptography standards, and global companies and government agencies are also pushing ahead in earnest with transitions to PQC.

It added that adopting PQC requires support across related systems and applications beyond simply replacing certificates, and that the transition process may take from months to years depending on an organisation’s scale.

The DigiCert ONE platform provides Quantum Central as part of a Quantum Ready strategy. It supports structured PQC migration by identifying cryptographic assets within an organisation and pinpointing certificates that require a transition to PQC.

Na Jung-joo (나정주), DigiCert’s Korea country manager, said the range of digital assets that companies must protect is rapidly expanding beyond people to include devices, AI agents and content as digital transformation accelerates. He said major trends such as shorter certificate validity periods, an increase in machine identities, the arrival of the quantum computing era and AI governance are not separate tasks but should be approached through a single integrated trust strategy. He said DigiCert plans to focus all capabilities with its distributor, SK Networks Service, so companies can respond proactively to these changes and achieve sustainable growth based on digital trust through the DigiCert ONE platform.
