  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.}
