With the development of computer network technology and the popularity of e-commerce, many businesses from traditional business thinking and mode of operation go to the e-commerce transactions. Computer network is an open system, but its openness lead to considerable security vulnerabilities and security threats in computer networks, Types of resources in the network can easily be illegally accessed and copied,while the openness of Internet has brought the transaction to the business transaction security risks,these risks are manifold,which is very important aspect is how to confirm the transaction paries whether the desired status and legal status of network resoures to authenticate the visitor. Identity authentication technology has become one of the most important technologies in network secrity.Password authentication is one of the most simple and commonly used network authentication mechanism.The more commonly used password authentication is based on static password authentication technology,which is characterized by simple,easy to use.However,as a diversification of means of network attacks, Static password authentication technology Static password authentication technology has its security flaws,which is being affected by various means of attack in the network. High demand for network security applications has reached less than their requirements.One-time password authentication technology is used to authenticate the user who is one-time legal status, that are each password only used once, each time authentication is to use a different password. One-time password authentication technology eliminate the majority of security flaws of the static password authentication technology,which is to help fight a static password authentication technology by the major security threats facing and attacks, applications for the network provides a more secure and reliable user authentication security.In this dissertation, one-time password authentication technolog'the basic principles, implementation, and security has been analysed in depth. Based on this argument, improvements on one-time password technology increased one-time password authentication scheme to resist attacks against the capacity, its security has been enhanced.
