New Research on Secret Sharing and Its Applications

Secret sharing is one of the most popular cryptographic tools in network applications used to protect data.  For example, secret sharing has been used in cloud to strengthen data security. Shamir’s threshold secret sharing scheme which was proposed originally in 1979 is the most popular scheme in the literature.  In this talk, I will briefly introduce Shamir’s scheme and point out some interesting properties.  Then, I will introduce some new research problems on the secret sharing and its application to group authentication.
