This scheme takes advantage of a trusted computing platform with a trusted computing module, which has excellent features such as security storage, remote attestation, and so on. These features effectively ensure trustworthiness of the disaster tolerant point. Furthermore, distributed storage based on Erasure code not only disposes the storage problem about a great deal of data, but also preferably avoids one node invalidation, alleviates network load and deals with joint cheat and many other security problems. Consequently, those security enhancement technologies provide mass data with global security protection during the course of disaster tolerance.展开更多

文摘This paper proposes a security enhancement scheme for disaster tolerant systems based on trusted computing technology which combines with the idea of distributed threshold storage. This scheme takes advantage of a trusted computing platform with a trusted computing module, which has excellent features such as security storage, remote attestation, and so on. These features effectively ensure trustworthiness of the disaster tolerant point. Furthermore, distributed storage based on Erasure code not only disposes the storage problem about a great deal of data, but also preferably avoids one node invalidation, alleviates network load and deals with joint cheat and many other security problems. Consequently, those security enhancement technologies provide mass data with global security protection during the course of disaster tolerance.
