Security against simple eavesdropping attacks is demonstrated for a recently proposed quantum key distribution protocol which uses the Fibonacci recursion relation to enable high-capacity key generation with entangled photon pairs. No transmitted pairs need to be discarded in reconciliation; the only pairs not used for key generation are those used for security-checking. Although the proposed approach does not allow eavesdropper-induced errors to be detected on single trials, it can nevertheless reveal the eavesdropper's action on the quantum channel by detecting changes in the distribution of outcome probabilities over multiple trials, and can do so as well as the BB84 protocol. The mutual information shared by the participants is calculated and used to show that a secret key can always be distilled.
