Research and Implementation of One-Time Password Authentication in Computer Networks

Some usual one.time password authentication protocols are analyzed. A practical efficient one.time password authentication implementing method is presented based on the symmetric algorithm, which conquers usual challenge.response protocol weakness and can protect user's identity and avoid replay attack etc. It also can boost up the security of the application security system by integrating with it in networks. And the correlative issues are discussed deeply such as security, reliability and so on.
