Many eﬃcient secret sharing schemes for general access structures have
been developed in eﬀorts to deal with the problems of multi-party computations (MPC),
threshold cryptography, and access control. In this paper, we have proposed a novel secret
sharing scheme with general access structures that is based on the key-lock-pair mechanism. In our scheme, the dealer can assess a real situation and design the corresponding
access structures, Γ = (Γ1; Γ2; : : : ; Γm). The diﬀerent qualiﬁed subset of participants in
Γ = (Γ1; Γ2; : : : ; Γm) can cooperate to reconstruct the shared secret, and no unqualiﬁed
participants can reconstruct the corresponding shared secret.
