A Distributed Networked Storage System with Secure Fault-Tolerant Codes

Regenerating codes are based on the concept of the network coding. Compared with the traditional codes used for fault-tolerant, it has advantages for its low redundancy and high efficiency. We present DSRC, a distributed networked storage system realizing a traditional regenerating code and a secure regenerating code in real network settings. We deploy and evaluate our DSRC prototype in a real network setting. We also use DSRC to experiment the empirical performance of storage schemes with the secure regenerating code. The evaluate shows that the secure regenerating code can achieve the security of the fault-tolerant process with a little higher throughput.
