Abstract:
Secret sharing is one of most popular cryptographic tools which has been proposed originally in 1979. Shamir’s threshold secret sharing 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 related research problems to the secret sharing, including secure and fair secret reconstruction, verifiable secret sharing, multi-secret sharing, cheater detection and identification in the secret reconstruction. Applications using the secret sharing will also be discussed, such as group key establishment in group communications and group authentication. Finally, I will briefly introduce my recent research paper on the implementation of a general secret sharing.
