A Piggybank Protocol for Quantum Cryptography
This is an incremental improvement for quantum cryptography, potentially enhancing security in communication systems.
The paper tackles the problem of secure communication by proposing a quantum mechanical version of the piggybank cryptography protocol, where the encryption transformation is sent separately but deciphering it alone does not break the system, though no concrete results or numbers are provided.
This paper presents a quantum mechanical version of the piggy-bank cryptography protocol. The basic piggybank cryptography idea is to use two communications: one with the encrypted message, and the other regarding the encryption transformation which the receiver must decipher first. In the quantum mechanical version of the protocol, the encrypting unitary transformation information is sent separately but just deciphering it is not enough to break the system. The proposed quantum protocol consists of two stages.
