  We construct general schemes for multi-partite quantum secret sharing using
multi-level systems, and find that the consistent conditions for valid
measurements can be summarized in two simple algebraic conditions. The scheme
using the very high dimensional mutually unbiased bases can in principle
achieve perfect security against intercept-resend attack; and for the scheme
using mutually biased bases, it reaches the optimal but non-perfect security at
4-level system. We also address the security issue against the general attacks
in the context of our multi-level schemes. Especially, we propose new protocol
to enhance both the efficiency and the security against the
entanglement-assisted participant's attack by incorporating
quantum-key-distribution and measurement-basis-encrypted schemes so that its
security is as robust as quantum-key-distribution.
