Secure Distributed Storage and Retrieval
In his well-known Information Dispersal Algorithm paper, Rabin showed a way to distribute information in n pieces among n servers in such a way that recovery of the information is possible in the presence of up to t inactive servers. An enhanced mechanism to enable construction in the presence of malicious faults, which can intentionally modify their pieces of the information, was later present...
متن کاملProbabilistically Secure Cooperative Distributed Storage
The trend towards self-organization of systems like peer-to-peer or mobile ad hoc networks generates increasing needs for distributed data management, in particular data backup and distributed storage functions that will themselves be self-organized and cooperative. Unfortunately, in such systems, the data stored are exposed to the selfishness (e.g. data discarded because of lack of resources) ...
متن کاملSecure Agents in a Distributed Storage System
The increased use of ubiquitous computing devices is resulting in networks that are highly mobile, well connected and growing in processing and storage capabilities. The nature of these ubiquitous systems, however, also increases the risk of building systems on devices that are undependable and potentially untrustworthy. This paper investigates the use of mobile autonomous agents, combined with...
متن کاملGeneric Secure Repair for Distributed Storage
This paper studies the problem of repairing secret sharing schemes, i.e., schemes that encode a message into n shares, assigned to n nodes, so that any n − r nodes can decode the message but any colluding z nodes cannot infer any information about the message. In the event of node failures so that shares held by the failed nodes are lost, the system needs to be repaired by reconstructing and re...
متن کاملSecure Distributed Data Storage in Cloud Computing
Cloud computing has gained great attention from both industry and academia since 2007.With the goal of providingusersmore flexible services in a transparent manner, all services are allocated in a “cloud” that actually is a collection of devices and resources connected through the Internet. One of the core services provided by cloud computing is data storage. This poses new challenges in creati...
