Multi-secret Sharing Scheme of Multi-dealer
摘要
Abstract
The traditional secret sharing schemes are all based on a single dealer. However, in reality, maybe there are many applications where the shared secrets are commonly maintained by several dealers. This paper proposes a novel secret sharing scheme based on the multi-dealer by means of Homogeneous linear recursion sequence and discrete logarithm problem. In this scheme, several dealers can commonly maintain the secret and the secret can be dynamically renewed by any dealer. In the secret updated phase, the dealer just needs to publish a little public information instead of redistributing the new secret shadows. Its security is based on the security of RSA cryptosystem and the intractability of discrete logarithm problem. Verification result shows that the scheme is secure and efficient.关键词
