Jakarta (ANTARA) - The Indonesian government is preparing quantum-resistant cryptographic technology to anticipate data security risks as the national digital economy continues to grow.

"To protect the digital economy, the government is developing quantum-resistant cryptography to mitigate the 'Harvest Now, Decrypt Later' (HNDL) risk—a scenario where encrypted data is stolen today with the intent of decrypting it in the future using quantum computers," Coordinating Minister for Economic Affairs Airlangga Hartarto stated here on Monday.

This initiative involves the implementation of Post-Quantum Cryptography (PQC) and the establishment of a National Task Force for the Migration to Quantum-Resistant Cryptography, led by the National Cyber and Crypto Agency (BSSN).

Quantum-resistant cryptography refers to information protection methods designed to withstand the potential capability of quantum computers to break the cryptographic systems currently in use.

Airlangga noted that the growth in digital transactions must be matched by robust security.

Bank Indonesia recorded 12.99 billion digital payment transactions in the third quarter of 2025, representing a 38.08 percent year-on-year increase.

He identified the digital economy as a key pillar for achieving the target of 6 percent economic growth by 2027.

The Gross Merchandise Value (GMV) of Indonesia’s digital economy is approaching US$100 billion in 2025, marking a 14 percent growth compared to the previous year.

Regarding infrastructure, Airlangga emphasized that the development of data centers hinges on the availability of land, electricity, and water.

He stated that the current operational capacity of data centers stands at 600–700 megawatts, with an additional 1.3 gigawatts in the pipeline—representing an estimated investment value of US$15 billion to US$20 billion.

American multinational technology company NVIDIA is actively reviewing a US$4.5 billion investment proposal targeting the Batam Free Trade Zone.

In the trade sector, the value of Indonesia’s e-commerce market is projected to grow by more than 14 percent, reaching US$71 billion—making it the largest e-commerce market in Southeast Asia.

The government has set a target for e-commerce transactions during the National Online Shopping Day (Harbolnas) to reach Rp40 trillion (approximately US$2.22 billion) by the end of 2026—a 10 percent increase from the Rp36.4 trillion projected for 2025—as part of ongoing efforts to strengthen the e-commerce ecosystem.

Meanwhile, international cooperation in the field of AI, facilitated through the World AI Collaboration Organization (WAICO), is expected to channel US$8 billion to US$12 billion into Indonesia between 2026 and 2030.

The digital sector is positioned as a primary engine driving Indonesia toward its ambitious 6 percent economic growth target for 2027.

Achieving this benchmark requires an investment growth rate of 8 to 9 percent, backed by a capital inflow target of Rp2,258 trillion (US$125.44 billion), increased labor productivity, and the strengthening of value-added exports.

"Within this framework, the digital economy serves as a measurable engine for growth," Airlangga emphasized.
