The Design And Implementation Of Document Nonproliferation System Based On Data Storage

As digital libraries, e-commerce, multimedia transmission and other networkapplications continue to evolve, the data rapid growth from GB, TB to PB. The user havebecome increasingly demanding of the data security, so new research is done to documentnon-proliferation. Not only did a study of documents used, but also the paper researchedthe security of communication of the mass information net users node and its own security.It made the research of the safety of the communication between the node and node in thenetwork of huge amounts of information. It took use of the roup key management schemebased on LKH, and made better the key distribution and key updated of the system. And itmade a contrast from the cost of communication. The paper setted the attributes of safetyin order to manage the documentation, at the same time, it took use the technology ofencryption and decryption when people used a USB device to transmit documentation inorder to prevent the leak from using the USB device. It made the analysis the encryptionand the decryption too. The paper took use of the technology of remote mirror in order totake precautions against the lost of document when the disaster or other causes occurred.At the same time, it improved the technology of remote mirror, used the synchronous andasynchronous mirror, and it used the batching of the requesting of writing. At the end, itimproved the disposing of a group of requesting of writing in the node of master and slave,which can better satisfy the data consistency and data recovery rate requirements.
