## What is Quantum Shieldz Cipher(QSC)?

Quantum Shieldz Cipher는 사용자의 스마트폰과 함께 작동하는 독립형 음성 암호화 장치입니다. 통화하는 사용자의 음성을 양자난수생성기(QRNG, Quantum Random Number Generator)가 생성하는 암호 키로 안전하게 암호화하여 상대방에게 전송함으로써, 스파이웨어를 이용한 도청이나 원하지 않는 녹음을 차단합니다. Quantum Shieldz Cipher는 자신의 스마트폰과 연동되는 간단하면서도 강력한 보안을 갖춘 통신 장치입니다.
