Special secret sharing scheme with the function of assignment
摘要
A concept of secret sharing scheme with the function of assignment is proposed. It provides great capabilities for many practical applications. In this scheme, the dealer can randomly assign one or more than one participant to get the secret at any time, but these participants can get nothing about the secret before that moment. At the same time, the other participants cannot get any-thing about the secret by stealing the secret value when it is transferred. However, if the dealer is lost, a certain number or more participants of them can reconstruct the secret by cooperating. In order to clear this concept, an illustrating scheme with geometry method and a practical scheme with algebra method is given.
