Quantum cryptography: individual eavesdropping with the knowledge of the error-correcting protocol
D. B. Horoshko · Quantum Electronics · 2007
The quantum key distribution protocol BB84 combined with the repetition protocol for error correction is analysed from the point of view of its security against individual eavesdropping relying on quantum memory. It is shown that the mere knowledge of the error-correcting protocol changes the optimal attack and provides the eavesdropper with additional information on the distributed key.
