Archistar

Last updated

Archistar is a software framework [1] to build distributed storage system on the basis of secure fragmentation and information dispersal. It is dedicated to the development of a secure distributed storage architecture for trustworthy cloud usage. The Archistar framework combines methods from Byzantine fault tolerance, secret sharing, and additional tools from cloud cryptography to achieve its goal and parts of it are released as open-source software. A non-functional goal is to provide a base framework for further research into this topic: to achieve this, focus has been set on readability and open-source licenses have been used for all prototype code.

Secret sharing

Secret sharing refers to methods for distributing a secret amongst a group of participants, each of whom is allocated a share of the secret. The secret can be reconstructed only when a sufficient number, of possibly different types, of shares are combined together; individual shares are of no use on their own.

Open-source software software licensed to ensure source code usage rights

Open-source software (OSS) is a type of computer software in which source code is released under a license in which the copyright holder grants users the rights to study, change, and distribute the software to anyone and for any purpose. Open-source software may be developed in a collaborative public manner. Open-source software is a prominent example of open collaboration.

Current Features as of November 2013

Netty is a non-blocking I/O client-server framework for the development of Java network applications such as protocol servers and clients. The asynchronous event-driven network application framework and tools are used to simplify network programming such as TCP and UDP socket servers. Netty includes an implementation of the reactor pattern of programming. Originally developed by JBoss, Netty is now developed and maintained by the Netty Project Community.

AIT Austrian Institute of Technology is Austria's largest Research and Technology Organization (RTO), employing about 1,300 people mostly based at the main facilities Vienna Tech Gate, Vienna TECHbase, Seibersdorf, Wiener Neustadt, Ranshofen and Graz.

Secure multi-party computation is a subfield of cryptography with the goal of creating methods for parties to jointly compute a function over their inputs while keeping those inputs private. Unlike traditional cryptographic tasks, where cryptography assures security and integrity of communication or storage and the adversary is outside the system of participants, the adversary in this model controls actual participants. These types of tasks started in the late 1970s with the work on mental poker, cryptographic work that simulates game playing/ computational tasks over distances without requiring a trusted third party. Note that traditionally, cryptography was about concealing content, while this new type of computations and protocol is about concealing partial information about data while computing with the data from many sources, and correctly producing outputs.

Shamir's Secret Sharing is an algorithm in cryptography created by Adi Shamir. It is a form of secret sharing, where a secret is divided into parts, giving each participant its own unique part.

Berkeley DB (BDB) is a software library intended to provide a high-performance embedded database for key/value data. Berkeley DB is written in C with API bindings for C++, C#, Java, Perl, PHP, Python, Ruby, Smalltalk, Tcl, and many other programming languages. BDB stores arbitrary key/data pairs as byte arrays, and supports multiple data items for a single key. Berkeley DB is not a relational database.

A GPL linking exception modifies the GNU General Public License (GPL) in a way that enables software projects which provide library code to be "linked to" the programs that use them, without applying the full terms of the GPL to the using program. Linking is the technical process of connecting code in a library to the using code, to produce a single executable file. It is performed either at compile time or run-time in order to produce functional machine-readable code. There is a public perception, so far unsupported by any legal precedent or citation, that without applying the linking exception, a program linked to GPL library code may only be distributed under a GPL-compatible license. The license of the GNU Classpath project explicitly includes a statement to that effect.

GNU Classpath

GNU Classpath is a free software implementation of the standard class library for the Java programming language. Most classes from J2SE 1.4 and 5.0 are implemented. Classpath can thus be used to run Java-based applications. GNU Classpath is a part of the GNU Project. It was originally developed in parallel with libgcj due to license incompatibilities, but later the two projects merged.

Filesystem in Userspace (FUSE) is a software interface for Unix-like computer operating systems that lets non-privileged users create their own file systems without editing kernel code. This is achieved by running file system code in user space while the FUSE module provides only a "bridge" to the actual kernel interfaces.

A source-code repository is a file archive and web hosting facility where a large amount of source code, for software or for web pages, is kept, either publicly or privately. They are often used by open-source software projects and other multi-developer projects to handle various versions. They help developers submit patches of code in an organized fashion. Often these web sites support version control, bug tracking, release management, mailing lists, and wiki-based documentation...

Software relicensing is applied in open-source software development when software licenses of software modules are incompatible and are required to be compatible for a greater combined work. Licenses applied to software as copyrightable works, in source code as binary form, can contain contradictory clauses. This requirements can make it impossible to combine source code or content of several software works to create a new combined one.
