Abstract
A method is provided that protects electronic Identity information based on key derived operation. The method includes using an electronic Identity server to send an application derived identifier of the application and user electronic Identity code to a host security module that randomly generates an application master key, encrypts the application derived identifier with the application master key, and gets an application encryption key. The host security module encrypts the user electronic Identity code with the application encryption key, and gets an encryption document. The electronic Identity server codes the encryption document and an application identity code, and gets an application electronic Identity code. The electronic Identity server uses the application electronic Identity code as the user identifier.
