A MESSAGE PASSING INTERFACE WITH ENHANCED SECURITY

OBJECTIVE:

The main objective of this system is to implement the security in the

Message Parsing Interface by integrating the encryption and decryption algorithms

in to the MPICH2 library with the standard MPI Interface.

PROBLEM STATEMENT:

The problems found in existing system as, Threat to the confidentiality of

the data shared among the nodes in the computing clusters of open network.

Anybody can access to the data in an open network of computer clusters. Due to

this the consistency of the data received by the processes in the network is low.

This may cause to process failure. Unauthorized access to the security-sensitive

messages by entrusted processes can lead to security breaches.

ABSTRACT:

The Message Passing Interface (MPI) is a library specification for message-

passing among the nodes of computer clusters of open network. Message Passing

Interface (MPI) is a standardized and portable message-passing system designed

by a group of researchers from academia and industry to function on a wide variety

of parallel computers.MPI is one of the most popular communication protocols for

cluster computing environments.

A computer cluster consists of a set of loosely connected computers  that

work together so that in many respects they can be viewed as a single system.

Clusters are usually deployed to improve performance and availability over that of

a single computer. But, the computer clusters are connected to the multiple number

of nodeswithin the network over the internet. It leads to the threat to the

confidentiality of the data shared among the multiple processes in the computer

cluster. This paper provides a systematic approach to improve the security in the

Message Parsing Interface by implementing the encryption and decryption

algorithms to the MPI libraries without changing the application programming.

EXISTING SYSTEM:

MPICH2 is an implementation of the Message-Passing Interface  (MPI). The

goals of MPICH2 are to provide an MPI implementation for important platforms,

including clusters, SMPs, and massively parallel processors. It also provides a tool

for MPI implementation research and for developing new and better parallel

programming environments.

DISADVANTAGES:

Threat to the confidentiality of the data shared among the nodes in the

computing clusters of open network.

Anybody can access to the data in an open network of computer

clusters. Due to this the consistency of the data received by the

processes in the network is low. This may cause to process failure.

Unauthorized access to the security-sensitive messages by untrusted

processes can lead to security breaches.

PROPOSED SYSTEM:

The proposed system is ES-MPICH2 framework implemented based on the

MPICH2. In this to provide the data confidentiality we are providing security for

MPI protocol by encrypting and decrypting the messages sent among the

computing nodes. Encryption algorithms are integrated into the MPICH2 library at

communication channel level of the MPICH2.

ADVANTAGES:

Provides security for the data shared among the computing nodes by

implementing the encryption and decryption algorithms.

By using the block ciphers the integrity of data is maintained.

The data shared among the nodes in the computer cluster are made

confidential without changing the source code of applications that are

runs under the MPI.
