  Among the problems to guarantee secrecy for in-transit information, the
difficulties involved in renewing cryptographic keys in a secure way using
couriers, the perfect secrecy encryption method known as One-Time-Pad (OTP)
became almost obsolete. Pure quantum key distribution (QKD) ideally offers
security for key distribution and could revive OTP. However, special networks
that may need optical fibers, satellite, relay stations, expensive detection
equipment compared with telecom technology and the slow protocol offer powerful
obstacles for widespread use of QKD. Classical encryption methods flood the
secure communication landscape. Many of them rely its security on historical
difficulties such as factoring of large numbers -- their alleged security
sometimes are presented as the difficulty to brake encryption by brute force.
The possibility for a mathematical breakthrough that could make factoring
trivial are poorly discussed. This work proposes a solution to bring perfect
secrecy to in-transit communication and without the above problems. It shows
the key distribution scheme (nicknamed KeyBITS Platform) based on classical
signals carrying information but that carry with them recordings of quantum
noise. Legitimate users start with a shared information of the coding bases
used that gives them an information advantage that allows easy signal recovery.
The recorded noise protects the legitimate users and block the attacker's
access. This shared information is refreshed at the end of each batch of keys
sent providing the secret shared information for the next round. With
encryption keys distilled from securely transmitted signals at each round OTP
can be revived and at fast speeds.
