Cryptographic Security for a High-Performance Distributed File System



INTRODUCTION :

Security is quickly becoming a mandatory feature of data storage systems. Today, storage space is typically provided by complex networked systems. These networks have traditionally been confined to data centers in physically secured locations.
With the availability of high-speed LANs and storage networking protocols such as FCIP and iSCSI , these networks are becomin ....etc

Computing System is a collection of processes operating on data objects.

Persistent data objects should be named and saved on nonvolatile storage device.

Named data objects are files.

A file system is a major component in an OS.

A Distributed File System(DFS) is an implementation of file system.

Abstract
We have developed Ceph, a distributed file system that provides excellent performance, reliability, and scalability. Ceph maximizes the separation between data and metadata management by replacing allocation tables with a pseudo-random data distribution function (CRUSH) designed for heterogeneous and dynamic clusters of unreliable object storage devices (OSDs). We leverage device intelligence by distributing data replication, failure detection and recovery to semi-autonomous OSDs running a specialized local object file system ....etc

INTRODUCTION
A file is a collection of binary data. A file could represent a program, a document or in some cases part of the file system itself. In modern computing it is quite common for there to be several different storage devices attached to the same computer. A common data structure such as a file system allows the computer to access many diffe ....etc

Distributed-Input-Distributed-Output (DIDO) Wireless Technology



Abstract

Distributed-Input-Distributed-Output (DIDO) wireless technology is a breakthrough approach that allows each wireless user to use the full data rate1 of shared spectrum simultaneously with all other users, by eliminating interference between users sharing the same spectrum. With conventional wireless technologies the data rate available per user drops as more users share the same spectrum to avoid interference, but with DIDO, the data ....etc
