Abstract
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 (Advanced Encryption Standard, AES). The proposed algorithm, we named Grid Secure Storage System (GS3), has been implemented on top of the Grid File Access Library (GFAL) of the gLite middleware, in order to provide a file system service with cryptography capability and POSIX interface. The choice of implementing GS3 as a file system allows to protect also the file system structure, and moreover to overcome the well-known problem of file rewriting in gLite/GFAL environments. This chapter describes and details both the GS3 algorithm and its implementation, also evaluating the performance of such implementation and discussing the obtained results.
