Quantum Shieldz® is a BI (Brand Identity) that collectively refers to products using EYL's core technology, QEC (Quantum Entropy Chip). It refers to EYL's quantum core technologies and products to solve the convergence security problem that matches the status of the 4th industrial revolution and next-generation IoT technology.

"People use random numbers every day, though they don't always realize it. When they log in to a website, send an email, or use a credit card number to shop online, their messages are encrypted with a random number. A random number, a random number, is encrypted, It is a key component of many security areas, including authentication, signing, key wrapping, etc. It keeps Internet communications and digital data safe from hackers."

Most cryptographic systems use a random number generated by a software algorithm (pseudo-random number generator) as a key for convenience and speed, but they are becoming increasingly vulnerable to hacking. Hackers can steal or guess encryption keys due to the weak entropy generated by poor random number generators.

EYL's core technology, quantum entropy technology, uses radioactive isotopes to achieve ultimate randomness (entropy) in nature. Since the source of randomness comes from quantum phenomena, it is always true randomness, proven by the laws of quantum physics.

EYL applies these core technologies to develop the world's "smallest, cheapest, fastest, and most energy efficient" quantum random number generator (QRNG) and applications that can be used for stronger convergence security in the 4th industry based on the Internet of Things.
