Hitachi Solutions Unveils DoMobile Ver.5 with Quantum-Resistant Security

On January 15, 2026, Hitachi Solutions Create Ltd. (HSC) introduced DoMobile Ver.5 in Japan, a major leap forward in remote access security. This latest version incorporates cutting-edge post-quantum cryptography (PQC) from 01 Quantum. This technology is crucial in preparing for future threats as quantum computing continues to advance.

The DoMobile platform, a trusted choice since 2002 for secure remote work, now includes PQC algorithms aligned with the standards of the National Institute of Standards and Technology (NIST). Existing users can upgrade to this fortified version at no extra cost. Yusaku Kurata from HSC highlighted the strategic importance of this upgrade in shielding against sophisticated threats, particularly ‘Harvest Now, Decrypt Later’ scenarios.

Confronting the Quantum Challenge

With hybrid work becoming commonplace, security in remote computing is paramount. While traditional encryption methods like RSA have been robust, quantum breakthroughs pose new risks. ‘Harvest Now, Decrypt Later’ tactics highlight vulnerabilities that need addressing. Thus, global authorities are rushing to standardize PQC, safeguarding future data integrity.

Financial sectors, under regulators like Japan’s Financial Services Agency, underscore the urgent need for this transition to secure sensitive information adequately.

A Leader in Remote Access Security

For more than two decades, HSC’s DoMobile has been a cornerstone of secure remote access. It serves approximately 7,000 companies across sectors, notably in finance, where security is critical. During the pandemic, it proved vital for seamless remote operations in Japan.

DoMobile Ver.5 positions HSC at the forefront of quantum-resistant technology, offering unparalleled protection against emerging cyber threats while maintaining reliable remote work solutions.

Key Attributes of DoMobile Ver.5

• Quantum-Resistant Security: Advanced PQC integration to defend against quantum threats.
• NIST Standards Compliance: Uses algorithms approved by NIST, ensuring robust, future-proof security.
• No Additional Costs: Current users receive features as part of standard updates.
• Market Pioneer in Japan: The first of its kind with integrated PQC, reinforcing HSC’s leadership.

The Growing Quantum Threat

As Q-Day approaches, the point where quantum computers may surpass traditional encryption, the urgency for robust security heightens. The rise of ‘harvest now, decrypt later’ attacks presents a formidable challenge for ongoing digital security needs.
