Abstract

The main objective is to develop a Message Passing Interface (MPI) implementation: to preserve confidentiality of messages communicated among nodes of clusters in an unprotected network. The message passing interface (MPI) is a standardized means of exchanging messages between multiple computers running a parallel program across distributed memory. In this technique public, private and secret keys are used. Keys are displayed to the receiver only if they accept the request or else displaying of key is not possible in the receiver side and also it won’t establish the Connection. In largely spread clusters, computing nodes are naturally deployed in a variety of computing sites. The Information processed in a spread cluster is communal among a group of distributed processes or client by high-quality of messages passing protocols (e.g. message passing interface - MPI) running on the Internet. Because of the open environment of the Internet, providing authentication for large-scale distributed clusters becomes a non-trivial and challenging problem. In this paper, the security of the MPI protocol has improved by encrypting and decrypting messages sent and received among computing nodes using MD5 algorithm.
