Quantum key distribution from a random seed
"It is designed a new quantum cryptography protocol that generates various secret and secure keys of the same size of the transmitted qubits, implying zero information losses between the interlocutors. Besides, generates key swapping between the two recipients of photons, without even sharing a past between them. This protocol differs from BB84 just in the classic procedures, using a random seed and asymmetric cryptography."
Quantum key distribution protocol with private-public key
"A quantum cryptographic protocol based in public key cryptography combinations and private key cryptography is presented. Unlike the BB84 protocol and its many variants two quantum channels are used. The present research does not make reconciliation mechanisms of information to derive the key. A three related system of key distribution are described."
