01 Quantum, Hitachi Solutions launch DoMobile Ver. 5

Executive Summary

• 01 Quantum Inc. and Hitachi Solutions Create Ltd. (HSC) have announced the launch of "DoMobile Ver. 5," a remote access system enhanced with post-quantum cryptography (PQC) technologies developed by 01 Quantum.
• The new version integrates NIST-standardized PQC algorithms (specifically those in FIPS 203) to protect against emerging quantum computing threats, such as "harvest now, decrypt later" attacks.
• DoMobile Ver. 5 is available to customers in Japan as of January 15, 2026, with no additional cost for existing customers to upgrade, positioning HSC as the first provider in Japan to offer PQC functionality in remote access software.

Key Details

• Product Launch: DoMobile Ver. 5, powered by 01 Quantum’s post-quantum cryptography technologies, is officially available in Japan.
• Security Enhancement: The system incorporates PQC into its public key cryptography framework to ensure long-term confidentiality and resistance to quantum-based cyber attacks.
• Standardization: The PQC algorithms used are standardized by the U.S. National Institute of Standards and Technology (NIST), specifically those published in FIPS 203.
• Commercial Terms: PQC-enhanced security is provided under standard licensing terms; existing customers can access the upgrade via the latest update with no optional contracts or additional costs required.
• Market Position: According to HSC, as of Jan. 15, 2026, DoMobile Ver. 5 is the first remote access software in Japan to offer PQC functionality.
• Target Audience & Reach: The platform serves approximately 7,000 companies and 36,000 users, with a significant presence in the security-sensitive financial sector.
• Threat Context: The update addresses risks from "harvest now, decrypt later" attacks, where adversaries collect encrypted data today to decrypt it once quantum capabilities mature.

Notable Quotes

• Yusaku Kurata, Executive Officer and Business Division Manager at HSC: "Since its launch in 2002, DoMobile has helped organizations maintain secure and reliable remote access. With DoMobile Ver. 5, we are taking the next major step by integrating postquantum cryptography to protect our customers from emerging risks such as harvest now, decrypt later attacks. By adopting NIST-standardized PQC ahead of the industry, we are ensuring that our users can continue working safely and confidently well into the quantum computing era."
• Andrew Cheung, Chief Executive Officer of 01 Quantum: "The transition to postquantum security is no longer theoretical, it is an operational necessity. Our collaboration with HSC on DoMobile Ver. 5 demonstrates how organizations can begin securing their remote access infrastructure today against tomorrow's quantum-enabled threats. We're proud to support a solution that brings PQC to market early and makes advanced protection accessible to tens of thousands of users without added cost or complexity."
