Maccabe and Patrick Widener}, title = {Scalable Security for {MPP} Storage Systems}, booktitle = {International Conference on Security and Management: Special Session on Security in Supercomputing Clusters}, year = {2007}, month = {July}, address = {Las Vegas, NV}, note = {Invited talk}, keywords = {LWFS, security model, pario-bib}, abstract = {Security is a critical but often ignored feature in massively paralell processing (MPP) I/O systems. The primary reason is that, in most cases, it is the quest for performance that drives (and funds) the I/O and file system research. Since security is not a primary objective, the researchers largely ignore the issues associated with security with the belief that they can patch a security model into the code base before the system goes into production. Unfortunately, existing security models for I/O are either inadequate with respect to the security they provide, or they severely hinder application performance because they are not designed to scale to the sizes of todays MPP system. This talk will discuss a joint effort by Sandia Laboratories and the University of New Mexico to investigating the use of Lightweight file systems (LWFS) as a means to provide efficient, secure, access to MPP system I/O devices. This talk will focus on LWFS security model. In particular we discuss the assumptions of our environment, the challenges with respect to security and scalability, and we describe and analyze security protocols that are both secure and scalable.} }
