| 发明名称 | Securing electronic control units using message authentication codes | ||
| 摘要 | A method of securing electronic control units (ECUs) using message authentication codes includes receiving a message authentication code (MAC) at an ECU; determining that the length of the MAC is greater than or equal to a predefined bit value; authenticating the MAC when the length of the MAC has been determined to be equal to or greater than the predefined bit value; and rejecting the MAC when the length of the MAC has been determined to be less than the predefined bit value. | ||

| 主权项 | 1. A method of securing electronic control units (ECUs) using message authentication codes, comprising the steps of: (a) receiving a message authentication code (MAC) at an ECU; (b) comparing, at the ECU, the length of the MAC with a predefined bit value; (c) ending further processing of the received MAC when the length of the MAC has been determined to be less than the predefined bit value; and (d) creating a comparison MAC to determine if data accompanying the MAC is authentic when the length of the MAC has been determined to be equal to or greater than the predefined bit value. | ||
