In this paper, the current security incidents of cloud storage and the popular security protection measures are deeply studied, combined with the existing results proposed a new cloud storage security solution. A trusted network node is installed between the client and the cloud storage server as the data encryption gateway, using the identity authentication method based on face recognition to authenticate and FPGA hardware acceleration technology, the user data can be transmitted to the cloud through ciphertext after encrypting the trusted gateway to improve the security of storing information in the cloud space. This scheme is designed as a framework for the implementation of the chip system and can be embedded in the home router, which has a wide application prospect. This design chooses 2012 Xilinx Company and ARM joint launch Zynq-7000 Chip, ZYNQ is the industry first integrates the arm company CORTEX-A series Core software and hardware comprehensive programmable platform, uses this chip to construct the SOPC system, and the transplant Linux system, Combining the advantages of ZYNQ and the idea of soft and hard collaborative design, the design of network server and the function of identity authentication are realized by using Cortex-a's performance advantages, and hardware acceleration is used to hardware the time-consuming encryption algorithm to improve the throughput rate. The paper realizes a cloud storage security system with different security levels based on the remote Reconfigurable method, and the average speed of data encryption uploading is about 4mb/s, and the average speed of sending to the client after downloading is approximately 2mb/s. The characteristic work of the thesis is mainly embodied in: first, the cloud storage user login authentication is based on the biometric authentication; Secondly, the system design adopts the method of soft and hard collaborative design, which optimizes the system structure and improves the running efficiency. And then the encryption algorithm by the network environment to complete remote reconfiguration, can achieve irregular replacement and improve security.
