一种抗窃听USB设备控制器
USB device controller resistant eavesdropping attacks
摘要
Abstract
Through in-depth analysis of USB transfer characteristics,this paper proposed a device controller to against eavesdropping attacks.It supported all transfer types and multi-pipe applications by combining block cipher module and stream cipher module with an endpoint independent design.The cipher modules embedded between the function interface and endpoint buffer could encrypt/decrypt data in the access process transparently.The interface and cipher modules design with pipelined transmission support substantially eliminated the impact of encryption/decryption to endpoint buffer access speed.Its implementation based on FPGA platform has been tested with Nios Ⅱ system on-chip and host software.The results show that the device controller can correctly encrypt/decrypt the bus data,which means anti-eavesdropping communication capability for USB peripherals.关键词
