Abstract: Quantum cryptography protocols have the feature of unconditional security, which is ensured by attack-detection. A new method is introduced to improve the precision of the estimation of the error rate in the information bits. With the new technique, more information about the error bits can be obtained, then the value of error rate of the information bits can be obtained by classical signal estimation. This method can improve the precision of attack-detection within a single running of all quantum cryptography protocols.
