Traditional RAID gradually becomes unable to satisfy most applications. It is reflected in two main respects, one is the security problem of data in RAID system, the other is that one RAID controller can not use several devices of different protocol. Now, the performance of RAID controller gets faster and faster, therefore, it is the right time to use software encryption module instead of hardware encryption to guarantee the data confidentiality. Furthermore, with the development of storage device, different disk interface appears. How to use the disk of different protocol in the same RAID controller is becoming a new research hotspot. As to the problems mentioned above, this paper presents a new multi-protocol disk array architecture that provides encryption on RAID, referred to as Encryption Multi-protocol RAID (EMRAID). EMRAID solution not only uses different interface to management the different kinds of device, but also adopts SEAL algorithm which is an efficient pseudorandom function family encryption algorithm. Analysis result indicates that EMRAID performs more efficiently than the single-protocol RAID, and the experiment shows that the encryption algorithm has certain loss (not very large) on I/O performance.
