| Abstract: | This paper proposes a special threshold secret sharing scheme among weighted participants which is based on the security of Rivest Shamir Adleman（RSA） cryptosystem, Shamir threshold secret sharing scheme and hash function. Each participant＇s secret shadow is selected and saved by the participant himself, and he can share many secrets with other participants by holding only one secret shadow. In the process of information exchange, it is not necessary to pass any confidential information and the scheme does not need a secure channel between each participant and the dealer. Theoretical analysis shows that the scheme is secure, effective and easy to implement. |
