Remarks on- An ideal multi-secret sharing scheme based on MSP

Zhi-hui Li Jing Li

Abstract: In 2010, C.- F. Hsu, Q.Cheng, X.M.Tang and B.Zeng proposed an ideal linear multi-secret sharing scheme based on monotone span programs (for short HCTZ scheme). This paper mainly makes an analysis about the problems in HCTZ scheme.Meanwhile, we presents an ecient ideal multi-secret sharing scheme based on monotone span programs for a family of access structures. The new scheme e ectively overcomes the de ciency of HCTZ scheme, and has the advantage of small calculation cost.

Category / Keywords: multi-secret sharing ; monotone span programs; a family of access structures; small calculation cost
