The commonly used technique for cheating detection in verifiable secret sharing (VSS) require public key systems. Based on linear integer secret sharing (LISS) scheme, this paper presents a private verifiable protocol over arbitrary access structure without public key systems, which can avoid cheating both from participants and dealers. For further consideration of share refreshing and renewal, this paper shows the proactive property of our scheme with new method. Furthermore, this paper
