OUR VISION

Complete Cipher And
protect the world.

The world is now facing a real threat from AI and quantum computing. However, we can no longer afford to keep the "only way" to protect the world a secret.

Therefore, we have decided to move forward with the social implementation of this technology.

OUR goal

Fully secure communications

Fully remote authentication

Stored in complete confidentiality.

Full proximity authentication

Furthermore, we will provide technology that enables the direct and instantaneous exchange of "value." As a result, we aim for a world where a multi-layered and high-turnover economy spreads throughout the globe, and no one suffers from hunger.

Purpose

With a CBDC, everyone can benefit from the cash economy.
Achieve completely secure communication and complete the internet.
Achieve complete confidentiality and eliminate information leaks.
A "generative national ID" that cannot be hacked or misused.
"Net contracts" that cannot be hacked, stolen, or tampered with.
"Messaging" that cannot be hacked, stolen, or tampered with.

Story

The threat of "AI" and "quantum computers" is imminent.

Our company was established in 2021 to provide technologies that can eliminate new threats that could fundamentally disrupt today's information society.

01

The Current State and Challenges of the Internet

Thanks to advancements in computer and communication technologies, our society has become highly information-driven. On the other hand, technologies for handling information securely have long been based on the premise of "security dependent on computational power."
Currently, there is a debate about the need to re-examine this very premise.

02

Challenges Facing Information Security

Four Threats to Information Security "Information theft, information tampering, identity theft, and cyber attacks" While countermeasures against these threats have continuously evolved, in many cases, it has been a recurring technological battle between attackers and defenders.

03

Information-Theoretic security

Our company focuses on the cryptographic design concept "Complete Cipher" (*), which is based on information-theoretic security.Information-theoretic security is a concept that defines the nature of security independently of the attacker's computing power.

04

Present and Future

We are developing and providing technology with the aim of adapting design principles to the modern information and communication environment and implementing them in a practical way for society.
Cipher Core emphasizes technological transparency and design principles to ensure that the social infrastructure handling information remains reliable for the future.

CEO

Takatoshi Nakamura

Representative Director, Information Security Research Institute

He holds four engineering degrees from the Department of Mechanical Engineering, Graduate School of Science and Technology, Keio University, and from the Departments of Marine Engineering, Mechanical Engineering, and Civil and Environmental Engineering, Massachusetts Institute of Technology (MIT).

After working at McKinsey & Company Japan, he served as a former researcher (visiting researcher) at the Massachusetts Institute of Technology (MIT), where he conducted research on computer architecture and information security.

He successfully developed a "cognitive processor," a non-von Neumann logic circuit, and based on this, completed quantum computer-resistant complete cipher technology.

Applying these results, he developed an end-to-end protection communication system, a remote authentication IoT system, and "Cipher Cash," a non-ledger-based cash-type CBDC platform. He is promoting the social implementation of information-theoretically secure cryptographic technology and working to establish next-generation information security and financial infrastructure.
