Post-Quantum Crypto

[INQ. NO. 2305E01] Given the rapid advances in quantum computing, existing cryptosystems could be disrupted by large-scale quantum computers, soon making them insecure. The longer that migration to post-quantum cryptographic security standards is delayed, the more
data is at risk.
In addition, the global market for quantum security is growing according to the U.S. National Security Agency (NSA) quantum-resistant cryptography standardization progress and timeline, and it is expected to grow rapidly
from 2024 onwards.
Information security technology in the quantum computer era can be largely divided into ‘security technology using quantum mechanics,’ and ‘threat analysis and responses by quantum computers.’

Quantum-resistant public key cryptography
SoftForum has organized products and solutions with a focus on quantum-resistant public key cryptography that is safe, even in large-scale quantum computers.
Softforum’s crypto is such a post-quantum based cryptographic library.
The cryptographic module provides functions such as postquantum-based symmetric key, public key, digital signature, key agreement, hash function, MAC, and random number generator.
The encryption function (API) corresponding to crypto encryption service can be called and used through an application.
The cryptographic module supports quantum-resistant key exchange cryptographic algorithm Kyber512/1024 and quantumresistant signature algorithms Dilithium-2/3/5, Falcon-512/1024, and SPHINCS.
Each API derives a common cryptographic key between two participants using key pair generation, key verification, key establishment algorithm.
