Key Generation Algorithm Sample Clauses

Key Generation Algorithm. Fig. 2.1 shows the block diagram of the proposed key generation algorithm. This report proposes the use of a LDPC decoder to reduce the disagreements in the bit sequences of users A and B caused by the measurement noise. A Hamming(7,3) decoder is then used to support a required public discussion between A and B to confirm their independent generation of the identical secret key in a manner which does not expose the key to an eavesdropper. The following algorithm generates the secret key in an eight step process: Step 1- Transceiver A sends pulse s(t) to transceiver B and then transceiver B sends a pulse of the same shape to transceiver A. As was mentioned above, the time separation between the pulse transmission times must be less than the coherence time of the channel, Tc, so both transceivers measure a signal resulting from the same channel impulse response.
