Abstract

The invention relates to the field of password authentication and discloses a security system and method that realizes the pattern of strong password authentication so as to resolves such problems in the prior password authentication pattern as the password being easily pried and attacked. The invention uses a security module for password authentication, and imports the user password into the security module instead of a host machine keyboard, adopts the random number with sufficient length as a user password, and the user password is not directly sent onto the network when logging in, and the dynamical information about the transmitted password is once for all, thereby being free from the attacks by various passwords. At the same time, the invention adopts a challenge/reply mechanism and a time synchronization mechanism, and combines the security function property of the security module, helping the method to prevent the counterfeit of a server and the assaults of a middleman apart from the fight against password assaults.

Description

technical field [0001] The present invention relates to the field of password authentication, in particular to a security system and method for realizing entity strong password authentication Background technique [0002] Password (Password) login authentication is a relatively simple and easy login authentication method commonly used by most application systems. In password login authentication, passwords are used to verify the user's identity when accessing the system. However, in the prior art, the password login authentication method has many security problems during use, such as the password is easy to be snooped, and it is easy to be attacked by the dictionary, exhaustive attempts, garbage search, information interception / replay, network data Attacks such as stream eavesdropping are threatened. In specific use, although the security of passwords can be enhanced to some extent by frequently changing passwords and increasing the length of passwords, this will also brin...
