Abstract

Computer network is an open system. However, due to its openness lead to computer networks exist a considerable number of security vulnerabilities and security threats, network types of resources can easily be accessed and copied illegally. Therefore, the network resources authenticate legitimate visitors becomes very important, authentication network security technology has become the most important technologies. More commonly used authentication technology is based on a static password authentication technology, which is characterized by a simple, easy to use, to a certain extent, can effectively secure user authentication. However, with the deepening of network applications and network attacks diversification, static password authentication technology because of its own security flaws are no longer adapted to the higher security requirements of network applications. Static password authentication technologies face major network attacks are: plain text passwords over the network vulnerable to eavesdropping attacks password; encrypted form of the password is vulnerable to interception / replay attack; Other attacks include forgery host attacks, internal staff attacks, dictionary attacks and so on. Static password authentication for security flaws technology, the industry made a one-time password authentication technology (One-Time Password Authentication), also known as dynamic password authentication techniques. One-time password authentication technology is used to authenticate the user's password is a one-time legal status, that are only used once every password, every authentication is to use a different password. Referred to here is not the user password password, but by the user passwords and other uncertain factors calculated authentication password. One-time password authentication technology eliminates static password authentication technology most security flaws, can effectively resist static password authentication technology faces major security threats and attacks for network application system provides a more secure and reliable user authentication security. Firstly, one-time password authentication technology, the basic principles, implementation and security in-depth analysis. On this basis, for two typical one-time password authentication scheme -S/KEY sequences password authentication scheme and SAS-2 certification schemes are described in detail and in-depth research. By studying these certification schemes work process analysis of these certification programs as well as its safety improvement programs, and to point out the existence of some security flaws. In the comprehensive plan and the one-time password authentication scheme based on improvement, this paper presents a new one-time password authentication scheme-NOTP certification programs (New One-Time Password Authentication Scheme), and implemented based on a novel of this program sexual Password Authentication System-NOTP authentication system. NOTP certification program has certified simple steps, execution performance, without re-initialization, the user can arbitrarily modify the password, and so on. Meanwhile, NOTP certification program also enhanced ability to resist various
