Abstract
The authorization method for an electronic device comprises to receive and store a first encrypted password generated by a remote device performing an irreversible operation on a first dynamic password, to receive an input password in response to a power-on command, to perform an irreversible operation on the input password to generate a second encrypted password, and to compare the first encrypted password and the second encrypted password. When the first encrypted password is same as the second encrypted password, the electronic device is started to complete a startup procedure and the remote device updates the first dynamic password to a second dynamic password.
Claims20
An authorization method for an electronic device, comprising:
- receiving and storing a first encrypted password generated by a remote device performing an irreversible operation on a first dynamic password;
- receiving an input password in response to a power-on command;
- performing the irreversible operation on the input password to generate a second encrypted password;
- comparing the first encrypted password and the second encrypted password;
- and
- when the first encrypted password is same as the second encrypted password:
- starting the electronic device to complete a startup procedure;
- and
- updating the first dynamic password to a second dynamic password by the remote device.
An authorization system for an electronic device, comprising:
- a remote device for generating a first dynamic password, and performing an irreversible operation on the first dynamic password to generate a first encrypted password;
- and
- a first electronic device, coupled to the remote device to receive the first encrypted password, wherein the first electronic device further comprises:
- a controller;
- a memory, coupled to the controller, for storing the first encrypted password;
- and
- an input-output interface, coupled to the controller, for receiving an input password in response to a power-on command,
- wherein the controller performs the irreversible operation on the input password to generate a second encrypted password, and compares the second encrypted password with the first encrypted password,
- wherein when the first encrypted password is same as the second encrypted password, the controller controls the first electronic device to complete a startup procedure.
An electronic device, comprising:
- a controller;
- a memory coupled to the controller for storing a first encrypted password generated by a remote device;
- and
- an input/output interface coupled to the controller for receiving an input password in response to a power-on command,
- wherein the controller performs an irreversible operation on the input password to generate a second encrypted password, and compares the second encrypted password with the first encrypted password,
- wherein when the first encrypted password is same as the second encrypted password, the controller controls the electronic device to complete a startup procedure.
