Abstract

In this paper, a conference key multicasting scheme is proposed and analyzed. Each Network user U i is associated with a key pair (x i , Y i ), where x i is a secret key and y i is a public key. A sealed lock is constructed from the public keys so that conference key can be enciphered by a chairperson and broadcasted to users in the network system, while only the authorized participants can recover the conference key. The packed sum property aspect of the well known knapsack problem together with the concept of secret sharing is utilized to accomplish the construction of a sealed lock.
