| Abstract （English） |
A key distribution scheme is a method to distribute off-line initial private pieces of information among a set of users, such that each group of a given size can compute a common key for secure conference. In this paper, we consider a ramp model for key distribution scheme. In the ramp model, the required resources can be reduced at the cost of a secerity degradation which depends on the size of users. We define a ramp model for key distribution scheme, show lower bounds on the size of the piece of a user's information and design a ramp model for key distribution scheme. |
