摘　　要：Abstract Key distribution patterns （KDPs） are finite incidence structures satisfying a certain property which makes them widely used in minimizing the key storage and ensuring the security of communication between users in a large network. We construct a new KDP using t-design and combine two ω-KDPs to give new （ω- 1）-KDPs, which provide secure communication in a large network and minimize the amount of key storage.Abstract Key distribution patterns （KDPs） are finite incidence structures satisfying a certain property which makes them widely used in minimizing the key storage and ensuring the security of communication between users in a large network.
