The invention discloses a trusted measurement authentication interaction method and device for a charging control system, which are applied to the charging control system. The charging control systemincludes a charging control unit and a charging controller; The authentication interaction method includes the following steps: the charging controller sends a measurement request frame to the charging control unit; the charging controller receives an application response frame fed back by the charging control unit according to the measurement request frame to establish a trusted connection pipeline; the charging controller calls trusted kernel proxy to generate a verification data frame and sends the verification data frame to the charging control unit; the charging controller receives the verification response frame fed back by a trusted core charging control unit according to the verification data frame, and the verification response frame includes a verification result; and when the verification result is passed, a program in the charging controller is loaded and operated. By using the trusted measurement authentication interaction method of the charging control system of the invention, the problem of lack of safety protection of an unattended terminal can be effectively solved, and active decision safety immunity of a charging pile to a malicious code is achieved.
