PASSWORD REMOTELY AUTHENTICATION METHOD BASED ON THE INTELLIGENT CARD AND AN INTELLIGENT CARD, A SERVER AND SYSTEM THEREOF

摘要

A password remotely authentication method based on the intelligent card, and the intelligent card, the server and the system thereof, and a method and a system for password transformation. The password remotely authentication method includes: the server generates the encrypted user information by using the system key and the user identifier inputted as the first hash function value and the user password inputted as the second hash function converse function value, and stores the encrypted user information to the intelligent card; when logging in the server, the intelligent card makes exponential operation for the encrypted user information with the second hash value as the power, and then obtaining the second encrypted user information, and calculates the third hash function value by using the second encrypted user information as an input, and sends the logging request message including the third hash function value to the server; the server validates the received third hash function value by the first hash function value and the second hash function value so as to realize password authentication.
