ITCEN Group security company ITCEN PNS said on Wednesday it will participate in efforts to standardise NTRU+, a quantum-resistant cryptography (PQC) algorithm developed with proprietary domestic technology.

NTRU+ is a homegrown quantum-resistant cryptography (KpqC) standard algorithm candidate selected as a key encapsulation mechanism (KEM) technology. Compared with existing standard technologies, it offers strong computing speed and high implementation efficiency on low-spec devices, making it an alternative technology applicable to industrial sites and lightweight hardware environments, the company said.

NTRU+ has completed submission of a draft standard aimed at selection as a national standard technology in the information security field of broadcasting and telecommunications standards in 2026, and it is being reviewed by the relevant standards committee, the company said. It has also submitted an Internet-Draft to the Crypto Forum Research Group (CFRG) under the Internet Research Task Force (IRTF), and is following international standardisation procedures.

ITCEN PNS plans to use its participation to expand the scope for applying PQC across industries, including financial networks, public infrastructure, industrial control networks, digital assets and edge and IoT environments. Linking its existing security solution capabilities, including its mobile integrated security solution AppIron Suite and its KCMVP-certified encryption module EdgeCrypto, it plans to progressively develop next-generation security businesses such as PQC-based mutual authentication, link encryption, certificate management and digital asset protection.

ITCEN PNS CEO Won-gyu Park (박원규) said, "The advent of the quantum computing era is demanding fundamental changes to existing security systems, and quantum-resistant cryptography is a key security technology that financial, public and industrial infrastructure must prepare for." He added, "Based on cooperation with leading domestic researchers, ITCEN PNS will enhance industrial applicability and commercialisation potential of homegrown PQC technology, and will actively pursue next-generation security businesses that can expand in the future to hardware-embedded security areas such as PQC-based security chips."
