We present a general scheme for multiparty-controlled teleportation of anarbitrary m-qudit ($d$-dimensional quantum system) state by using non-maximallyentangled states as the quantum channel. The sender performs m generalizedBell-state measurements on her 2$m$ particles, the controllers take somesingle-particle measurements with the measuring basis $X_{d}$ and the receiveronly need to introduce one auxiliary two-level particle to extract quantuminformation probabilistically with the fidelity unit if he cooperates with allthe controllers. All the parties can use some decoy photons to set up theirquantum channel securely, which will forbid some a dishonest party to eavesdropfreely. This scheme is optimal as the probability that the receiver obtains theoriginally unknown m-qudit state equals to the entanglement of the quantumchannel.
