OUR VISION

Protecting the World with Complete Cipher

The world now faces a real and present threat from artificial intelligence and quantum computing.

Keeping the only means of protecting the world hidden is no longer an option.

That is why we have chosen to bring Complete Cipher into practical use.

OUR GOAL

To protect information, we deliver four essential capabilities:

Complete Cipher Communication

— End-to-End Protected Communication

Complete Cipher Remote Authentication

— Secure Remote Identity Verification

Complete Cipher Storage

—Confidential Data Storage

Complete Cipher Proximity Authentication

— Secure Proximity-Based Identity Verification

Beyond information security, we are building technologies that enable the direct and instantaneous exchange of value—helping create a multi-layered, high-velocity global economy where no one suffers from hunger.

OUR PURPOSE

Our purpose is realized through six core implementations:

Bringing the benefits of a cash economy
to everyone through CBDC
Completing the Internet with Complete Cipher
Communication
Eliminating data breaches with Complete
Cipher Storage
A Generative National ID designed to prevent
unauthorized use and identity fraud
Net Contracts protected by Complete Cipher
against hacking, theft, and tampering
Messaging protected by Complete Cipher
against hacking, theft, and tampering

OUR STORY

AI and Quantum Computing Are Reshaping Information Security

The threat of artificial intelligence and quantum computing is at our doorstep.

Cipher Core, Inc. was founded in November 2025 to develop technologies capable of eliminating emerging threats that could fundamentally undermine today's information society.

01

The Internet Today: Progress and Challenges

Advances in computing and communication technologies have transformed society into one driven by information.
For decades, information security has been built on the assumption that computational difficulty can ensure security.
Today, that assumption is increasingly being reconsidered as artificial intelligence advances and quantum computing continues to evolve.

02

Challenges Facing Information Security

Information security continues to face four persistent threats:

  • Data Theft
  • Data Tampering
  • Identity Theft
  • Cyberattacks

Efforts to address these threats have continued to evolve, often resulting in an ongoing technological competition between attackers and defenders.

03

Information-Theoretic Security

Complete Cipher is our security foundation, rooted in information-theoretic security.
Rather than relying on computational assumptions, it is built on principles intended to remain secure in the age of artificial intelligence and quantum computing.
Information-theoretic security has been studied in cryptography for decades as an approach whose security properties are defined independently of an attacker's computational capability.

04

Building the Future

We transform these principles into practical technologies for today's information and communications environment.
Cipher Core is committed to security in both technology and design principles, helping ensure that the world's information infrastructure remains trustworthy for generations to come.

Leadership

Chief Executive Officer

Takatoshi Nakamura

Representative Director, Information Security Research Institute

Takatoshi Nakamura holds five engineering degrees: two from Keio University and three from the Massachusetts Institute of Technology (MIT), in Ocean Engineering, Mechanical Engineering, and Civil and Environmental Engineering.

After working at McKinsey & Company Japan, he became a Research Affiliate at MIT (1996–2014), where he conducted research in computer architecture and information security.

He established NTI, Inc. in 1996 and developed the Cognitive Processor, a non-von Neumann computing architecture, and subsequently developed Complete Cipher, an information-theoretically secure, quantum-resistant cryptographic architecture.

Building on this work, he created Complete Cipher Communication, an end-to-end protected communication platform; Complete Cipher Remote Authentication, an IoT-based identity verification system; and Cipher Cash, a ledgerless, cash-type CBDC platform.

Today, he leads Cipher Core's mission to establish next-generation information security and financial infrastructure through the practical adoption of Complete Cipher.
