GS3: a Grid Storage System with Security Features

Abstract

Technological trend and the advent of worldwide networks, such as the Internet, made computing systems more and more powerful, increasing both processing and storage capabilities. In Grid computing infrastructures, the data storage subsystem is physically distributed among several nodes and logically shared among several users. This highlights the necessity of a) availability for authorized users only, b) confidentiality, and c) integrity of information and data: in one term security. In this work we face the problem of data security in Grid, by proposing a lightweight cryptography algorithm combining the strong and highly secure asymmetric cryptography technique (RSA) with the symmetric cryptography (AES). The proposed algorithm, we named Grid secure storage system (GS 3 ), has been implemented on

Information dependability in distributed systems: The dependable distributed storage system

“…This paper extends previous work [8,9] mainly broadening the scope to reliability issues, thus turning into the wider dependability context to provide further investigation on the impact of dependability on the overall storage system. Furthermore, the reference architecture of D 2 S 2 is here specified identifying functionalities and modules of both its Client and Server, also providing and discussing new evaluation results obtained by testing the resulting implementation through real applications and against the former implementations.…”

“…To this purpose we can start roughly assigning reliability/availability commitments to the D 2 S 2 server side, while security issues are mainly in charge of the D 2 S 2 client. 8 …”

“…More specifically we have performed the same measurements of [8], where we evaluated GS 3 at the basis of the D 2 S 2 gLite implementation. Thus, in the experiments we have disabled the cache in order to effectively evaluate the actual operation response time, always operating on new files.…”
