Design and Implementation of a Kind of Cryptographic File System

Network file sharing is bringing the convenience information sharing to human, at the same time it also bringing new security risks inevitably. The existing Internet file-sharing systems, web disks are all rarely associated with file transfer and storage security questions. In order to strengthen the network file transfer and storage's security, this paper designed a HTTP-based secure network file storage system. The system through the cited RSA and AES encryption system for file encryption protection, and document key security management mechanism to ensure the document in the process of transmission and storage is security. Using IE ActiveX makes encryption and decryption on the client, and not to increase the burden of file server. The system's Design and Implementation is to improve the network file' security.
