Abstract

A dynamic cypher authentication system is applied to an electronic device having an authentication password. The system includes an input module, a password triggering module, an operation module, and an authentication module. The input module receives an operator password input by a user. The password triggering module generates a trigger signal and then generates a prompt password according to the trigger signal. The operation module performs a mathematical operation on the prompt password according to the operator password, so as to generate the authentication password. The authentication module receives a login password and compares the login password with the authentication password, so as to determine whether to authorize a login request on the electronic device.
