Claim Text:
1. A network locking method for a terminal, comprising: writing a network locking parameter into a first storage unit of the terminal; obtaining network locking parameter verification information and an unlocking code according to unique identification information of hardware of the terminal and the network locking parameter; and storing the obtained network locking parameter verification information into a second storage unit of the terminal, and storing the unlocking code, wherein obtaining the network locking parameter verification information according to the unique identification information of the hardware of the terminal and the network locking parameter comprises: calculating a first digest value for the unique identification information of the hardware of the terminal and the network locking parameter, and encrypting the first digest value using a private key in a preset asymmetric encryption key pair to obtain first network locking parameter verification information; and wherein obtaining the network locking parameter verification information according to the unique identification information of the hardware of the terminal and the network locking parameter further comprises: calculating a second digest value for the unique identification information of the hardware of the terminal and a public key in the asymmetric encryption key pair, and encrypting the second digest value using the private key in the asymmetric encryption key pair to obtain second network locking parameter verification information.
