Recursive Algorithm for Secure Dynamic Key Transmission Over Public Channels in Quantum Cryptology

As the number of communicating parties requiring secure dynamic key distribution over quantum channels increases, a method of minimizing the amount of data shared over the quantum channel for refreshing the key is required. A method for secure sharing of dynamic keys over public channels using quantum cryptology is proposed. A recursive algorithm is exemplified and the corresponding saving in communication capacity over the quantum channel and the computational complexity of the algorithm are analyzed
