Abstract
The authors propose a new finite ideal threshold scheme which provides Shannon perfect secrecy and can be used to handle the changeable master keys system in finite times without affecting any secret shadow. Since the idea was inspired by A. Shamir´s (1979) threshold scheme, this threshold scheme is introduced. The definition of the finite ideal threshold scheme is given. The dynamic secret is described. The security analysis of the method is considered.<>
