Abstract :
Recently, a secure broadcasting scheme was proposed which requires fewer broadcasting messages than other existing schemes. It is shown that in order to provide security, the operation of this proposed broadcasting cryptosystem becomes infeasible because a very large amount of information (~271 bits) must be kept by each user, and be sent for each broadcast
