Trusted reconfigurable device and using method thereof

Abstract

The invention belongs to the field of information security, and particularly relates to a trusted reconfigurable device and a using method thereof. As the characteristic of reconfigurability of the reconfigurable device is increasingly widely applied in engineering development, malicious attackers in the complex application environments of a network and the like also can utilize the characteristic of reconfigurability of the reconfigurable device to fulfill the aim of destructing or stealing important information and engineering design in the reconfigurable device by using the illegal means of falsifying and the like. In the invention, a method is provided for the transmission of configuration information and important data by arranging a controller, a cryptographic algorithm engine and the like in the reconfigurable device and establishing a trusted channel between the reconfigurable device and master control equipment by using the means of random numbers, a cryptographic algorithm, mutual authentication and the like; an integrity checking function is realized in a debugging interface module and a configuration module of the reconfigurable device; and the trusted reconfigurable device and the using method are provided for users by the trusted channel and an integrity checking unit.

Description

technical field [0001] The invention belongs to the field of computer trustworthiness. Background technique [0002] At present, the technical reasons for information security accidents are mainly the simplification of existing computer software and hardware structures, which leads to illegal use of resources. In order to solve hidden dangers of information security, trusted computing needs to start with improving the terminal's own protection capabilities and solve information security problems from the source. For example: hardware devices (especially SOC chips) are the basis of the entire computing system. A seemingly ordinary hardware device may contain logic bombs and sniffers. It is unknown what information it is collecting or when it will explode. [0003] In the network tax controller project that the author participated in, the network tax controller is mainly used to monitor the cash register terminal, record the communication records between the cash register te...

Problems solved by technology

However, we encountered how to reduce the risk of FPGA hardware configuration information and microprocessor operating belt being tampered with without affecting product performance, and how to quickly restore FPGA devices to normal working conditions when data has been tampered with. The problem

At present, the two major FPGA suppliers, Xilinx and Altera, have released their respective solutions for intellectual property protection of FPGA hardware configuration data and IP cores, but have not yet provided a design solution for how to prevent hardware quota data and firmware codes from being tampered with.
