在安全电子控制单元中启用特殊优先模式的授权方案

Authorization scheme to enable special privilege mode in secure electronic control unit

Abstract

本发明涉及在安全电子控制单元中启用特殊优先模式的授权方案,具体提供一种用于在不必认证软件的情况下绕过安全码来允许开发软件安装在生产控制器上的系统和方法。所述方法包括从控制器请求信息以及响应于该请求而在控制器中生成识别控制器的信息标签。所述信息标签被发送到生成授权标签的安全服务器,所述授权标签通过信息标签识别控制器并且生成用于所述标签的安全码。所述授权标签被呈送给控制器,并且如果控制器核实了该安全码,则所述控制器允许安装所述开发软件。
The invention relates to an authorization scheme to enable a special privilege mode in a secure electronic control unit, and concretely provides a system and method for by-passing a security code to allow developmental software to be installed on a production controller without having to authenticate the software. The method includes requesting information from the controller and creating an information ticket in the controller in response to the request that identifies the controller. The information ticket is sent to a secure server that creates an authorization ticket that identifies the controller from the information ticket and creates a security code for the ticket. The authorization ticket is presented to the controller and if the security code is verified by the controller, the controller allows the developmental software to be installed.
