Abstract
The network has become the main means of information exchange,while because of network globalization and its openness the network security problem brings more and more attention and concern.Identity authentication is the first line of defense in Web application system,its authentication technology is directly related to network security.This paper presents a dynamic password authentication scheme based on challenge-response protocol,according to static password identity authentication technology's security flaws.
