Abstract
A method for pre-verification of a code module when the code module is installed or updated in a virtual machine, comprising: loading codes in the installed or updated code module; performing code verification on the codes in the code module; if the code verification is passed, generating a certificate of the code module; and storing the code module passing the code verification and its certificate. The present invention also discloses a method for verification of a code module at runtime of the code module in a virtual machine, comprising loading codes in the code module; generating a certificate of the code module based on the loaded codes; if the generated certificate of the code module and a pre-stored certificate of the code module are identical, verifying the code module to be valid; otherwise performing a pre-verification on the code module.
