Research and Implement of a Security iSCSI Based on SSL

The existing scheme of disaster-tolerant cann't satisfy the requirments for confidential datum. The systemic framework of distributed secure storage is put forward. The structure of metedata servers, storage servers and the mechanism of data renewal are designed. According to the requirement for security of the storage system, the secure coding scheme of information dispersal algorithm based on cross-checksum is realized. When the users who have no authority access or the storage servers are faulty exhibiting Byzantine behavior, the shecme is effectively. The results show that the methods in this paper build a balance between the security and the computing cost, and it can meet the requirements of some special applications.
