Pseudo random number generators are vulnerable to hacking because they tend to have a predictable pattern hackers can exploit. The weak entropy problem is compounded for FinTech & IoT devices with limited access to physical random events such as mouse movement. EYL provides Quantum random number generator that extracts randomness from radioactive isotope put in the very tiny chip(3x3mm) in order to generate powerful encryption keys. EYL produces and supplies various security products such as crypto phones using QRNG's excellent cryptographic key generation device.
