The invention discloses a method for attacking Fourier transform quantum secret sharing systems, and relates to quantum secret communication technology. In the method, a specific measurement base is utilized to perform single particle measurement on the information carrier quantum bit, and partial secret messages are acquired according to a measurement result. According to the quantum-mechanical nature, due to the selection of the measurement base, the state of the measured quantum bit is just the eigen state of the measurement base, and the quantum state after measurement cannot be changed at all. The method can make a dishonest agent independently obtain partial key information, also can make several cooperated agents obtain more key information, and cannot introduce any error for normal communication so as not to be discovered by other users. The invention provides a method for effectively attacking the Fourier transform quantum secret sharing systems, which is simultaneously an effective method for testing the safety of the Fourier transform quantum secret sharing systems.
