Archistar is a software framework 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
Secret sharing (also called secret splitting) refers to methods for distributing a secret among a group, in such a way that no individual holds any intelligible information about the secret, but when a sufficient number of individuals combine t ...

open-source software
Open-source software (OSS) is computer software that is released under a license in which the copyright holder grants users the rights to use, study, change, and distribute the software and its source code to anyone and for any purpose. ...
. 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.
The first version of the Java implementations have been developed in a research project funded by the Austrian
