Abstract: A method of managing application installation is provided. The method includes receiving an application by an electronic device, determining an application signature key included in the application, if the application signature key matches a development signature key among the development signature key and a commercial signature key, verifying the application signature key in relation to whether the electronic device corresponds to information on a test electronic device defined in the application signature key, and installing the application based on a verification result of the application signature key.
