A scalable authentication model based on public keys

To solve the scalability problems of the identity authentication model based on CA for application in large distributed networks, adopting a rigorous binary tree code algorithm, we present a distributed identity authentication model based on public keys. The advantages of our model are described as follows: First, it has good scalability and is suitable for large-scale distributed networks. Second, the authentication path is short, with no more than two entities intervening. Third, it does not require users to inquire about certificate revocation lists.
