....multicast authentication problem. In the next section we describe this alternative approach. III. EFFICIENT AUTHENTICATION SCHEMES We concentrate on two approaches to authentication: public key signatures, and MACs. We do not address informationtheoretic authentication mechanisms, such as [10] [25], 6] which are inherently inefficient for groups of non trivial size. Public key signatures are perhaps the most natural mechanism for multicast authentication. Yet, signatures are typically long, and computing and verifying each signature requires a significant computational overhead. ....

....3 Efficient Authentication Schemes There are three approaches to authentication: information theoretic authentication, public key signatures, and MACs. Attempts at designing information theoretically secure (also called unconditionally secure) authentication schemes for large groups of receivers [12, 31] are 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 ....
