Fileshader : Entrusted Data Integration Using Hash Server

摘要

The importance of security is increasing in a current network system. We have found a bigsecurity weakness at the file integration when the people download or upload a file and proposea novel solution how to ensure the security of a file. In particular, hash value can be applied toensure a file due to a speed and architecture of file transfer. Hash server stores all the hashvalues which are updated by file provider and client can use these values to entrust file when itdownloads. FileShader detects to file changes correctly, and we observed that it did not showbig performance degradation. We expect FileShader can be applied current network systemspractically, and it can increase a security level of all internet users.
