Introduction

A SoftForum that sets a milestone for future security through quantum resistant cryptography.
It is necessary to prepare for new changes through quantum computer technology.
Quantum computer is a groundbreaking technology that can solve problems in seconds that are difficult to solve with conventional supercomputers even if it takes hundreds of years, and is called a game changer in the future industry. It is expected to bring about revolutionary changes in the field. Unlike existing computers that count the number of cases one by one, this method calculates numerous combinations of possibilities at once, can find the optimal financial investment or logistics transportation route, and helps solve the challenges in the field of life science, leading to new drug development. It can be used to provide clues. In this way, as quantum computers develop, ‘quantum jumps’ (rapid development in a short period of time) can be achieved in various fields.
Although there are positive aspects in which the development of quantum computers can achieve rapid progress in various fields, the threat caused by the changes brought about by quantum computers in the IT information security field that requires strong security channels and data protection for sensitive data and data transmission may become
Quantum computers will no longer be able to safely use algorithms such as RSA (Rivest-Shamir-Adleman) and ECC (elliptic curve cryptography), which are currently most widely used, through the Shore/Grover algorithm that utilizes quantum superposition computing technology. will be. Thus, as quantum computers advance, vulnerabilities in most cryptographic systems will emerge as new threat models, putting current public-key cryptosystem infrastructures used for e-commerce, digital signatures, and electronic identities at risk.
Recently, major companies and countries have increased interest and investment in the vast technological and social values that the upcoming quantum computer era will bring, and as a result, the development of quantum computers is accelerating. Given the accelerated development of quantum computing, cryptosystems used in existing systems may become insecure within a few years due to quantum computers, and if the corresponding technology is not converted quickly, it may be exposed to more risks.
Since 2016, NIST in the United States has been leading the process of developing and testing a set of quantum safe cryptographic algorithms, and so far, the algorithm selection process has been conducted over four rounds, and standardization is expected to be completed by 2024. This new cryptosystem uses various mathematical concepts and processes, such as lattice-based, that are not easily cracked by quantum computers. A new cryptographic system that is being standardized is an algorithm that can be safely used in an existing computer system, but is calculated so that a quantum computer cannot easily decipher it.
Information security technology in the quantum computer era can be largely divided into 'security technology using quantum mechanics' and 'threat analysis and response by quantum computer', and there is a quantum resistant encryption technology as a response technology to quantum computer threats. The global security market of quantum resistant cryptography is growing significantly according to the US NSA's 'Quantum Resistant Cryptographic Standardization Progress and Timeline'. We provide products and solutions.
Soft Forum has a continuous roadmap to apply various concepts such as hybrid systems (double encryption, double KEM, double signature, etc.) based on quantum resistant cryptography technology, and allows companies and governments to use quantum computers in current public key cryptographic algorithms. We are preparing to apply a new quantum resistant cryptographic algorithm that is safe even in this era.
In the future, institutions and enterprises will need to adopt new quantum-resistant cryptographic products and services to stay secure with great agility.
