....inherently inefficient. Some of the suggested schemes could only be used for a single authentication, and they all have storage (distribution) requirements which are in the same order as the total number of messages that can be authenticated. Another information theoretic scheme, of Blundo et al. [7], can be adapted for authentication, but requires storage which is exponential in the size of the multicast group; therefore it cannot be applied for large groups. Signatures: Public key signatures can be used for authentication. Such signatures are typically long and require a significant ....
