报告摘要: Secret sharing is a well known security scheme. Recently, researchers consider the secret sharing schemes with the repairable property. In this talk, we will introduce the concept of share repairability and discuss the different setting of the problem. Then we will discuss several repairable threshold schemes and the combinatorial properties of the scheme. We will give some constructions using various combinatorial objects. Several open problems will also be considered.
