  Quantum key distribution protocols constitute an important part of quantum
cryptography, where the security of sensitive information arises from the laws
of physics. In this paper we introduce a new family of key distribution
protocols and we compare its key with the well-known protocols such as BB84,
PBC0 and generation rate to the well-known protocols such as BB84, PBC0 and
R04. We also state the security analysis of these protocols based on the
entanglement distillation and CSS codes techniques.
