A non-interactive, simple and efficient Publicly Verifiable Secret Sharing (PVSS) is constructed based on the bi-linear pairing on elliptic curves, which has all advantages of Schoenmakers' PVSS. Moreover, in the scheme's distribution of shares phase, only using bilinearity of bilinear paring, anybody can verify that the participants received whether correct shares without implementing interactive or the non-interactive protocol and without construction so called witness of shares applying Fiat-Shamir's technique. Subsequently, in the scheme's reconstruction of secret phase, the released shares may be verified by anybody with the same method.
