Efficient sharing (broadcasting) of multiple secrets
Lein Harn · IEE Proceedings - Computers and Digital Techniques · 1995
Instead of using the conventional m-out-of-n perfect secret sharing scheme to protect a single secret among n users, the authors propose a secret sharing scheme based on one cryptographic assumption to protect multiple secrets. It is shown that, with this relaxation of the security requirement, secret sharing and some related secret-sharing problems, such as cheater detection and secret broadcasting, can be solved very efficiently.
