Multicast key disrtribution schemes based on Stinson – van Trang designs / Alekseychuk A. N., Konushok S. N. // Cybernetika i sistemny analiz.
The efficiency characteristics of multicast key distribution schemes based on (v, b, r, λ)-designs are investigated. The stability and connectivity of such designs are estimated. These estimates generalize and enhance the well-known estimates for the efficiency characteristics of multicast key distribution schemes based on incomplete block designs.
