Abstract:
Systems and methods provide quantum secured internet transport. Quantum key distribution (QKD) is made universally available to existing Transport Layer Security (TLS) Internet services without requiring modification of existing applications. QKD keys may be prefetched and transferred to user devices at secure sites using QKD over an optical link (e.g., a continuous wave fiber or free-space optical link). A proxy QKD TLS tunnel client and a QKD TLS tunnel server are transparent to the user devices and select QKD keys for use with existing TLS client and TLS server services to form a QKD TLS tunnel between the user devices for secure communication. One-time-pad (OTP) encryption uses pre-shared QKD keys to provide secure OTP based encryption.
