	abstract = {New results are presented for recently proposed rooted tree based secure multicast key revocation scheme [1,2] by studying the information theoretic properties of member revocation events .It is shown that the optimal average number of keys per person is given by the entropy of the member revocation event and the currently available solution correspond to the worst case or the maximum entropy scenario. It is shown that the proposed key assignment in [2] corresponds to optimal source coding and is susceptible to attack by compromise or collusion of multiple members.},

	abstract = {We present a scheme for shared secret generations by n members that combines the contributions the members in a fashion such that the individual contribution of each member is not exposed to anyone- including other members. We note that for an external attacker trying to break the n L-bit secrets of the members, the effective search space dimension is~nL, meaning that all n keys must be broken simultaneously in order to crack system integrity. We also note that the scheme provides "Unconditional Secrecy"[1].},
