Abstract
(English)
In this paper, we consider a ramp model for Key Predistribution System (KPS). In the ramp model, the required resources can be reduced at the cost of a security degradation which depends on the size of users. We define a ramp model for KPS, show lower bound on the size of the piece of a user's information and design a ramp model for KPS.
