DATA PROCESSING APPARATUS |
摘要 |
A data processing apparatus (30) comprising: a local source of data (4); a first controller (31); and a tamper-resistant second controller (32) configured to communicate with the first controller, the first controller being configured to control and receive data from the local source of data and from a sensing unit connected to the first controller via a communication interface and to perform a series of calculation operations on the data, wherein the second controller is configured to verify the integrity of a selected subset of the operations performed by the first controller. |

1. A data processing apparatus comprising:
a local source of data; a first controller; and a tamper-resistant second controller configured to communicate with the first controller and to verify integrity of a series of calculation operations performed by the first controller, the first controller being configured to control and receive data from the local source of data and from a sensing unit connected to the first controller via a communication interface and to perform the series of calculation operations on the data, wherein the first controller is configured to record history data derived from a start state and a finish state of the series of calculation operations and transmit the history data to the tamper-resistant second controller, the tamper-resistant second controller being configured to one of randomly and pseudo-randomly select and verify one of the calculation operations to verify integrity of the series of calculation operations using the history data. |
