An improved and efficient message passing interface for secure communication on distributed clusters

The main aim of this project is to provide secure communication among distributed clusters via Message Passing Interface (MPI). When a number of clusters associated to each other are increased then, it becomes a threat to security applications running on the clusters. To handle this security trouble, a MPI is built-up to protect the properties of security in an untrusted network. In the existing system, to generate the symmetric shared key, the participant provide only 1 byte size of random number so there is a chance to find out the key by the intruder. Furthermore, here only text message is passed between the clients. The proposed system is Enhanced Security for Message Passing Interface Chameleon version 2 (ES-MPICH2) in which it maintains the size of random number as 4 bytes, thus it is impossible to find out the key by the unauthorized person. This protocol is extended with features, such as secure file transfer utility and rekeying process. As well it supports to encrypt and decrypt the file upload by the user. We use secure algorithms like interpolation polynomial, AES and SHA-1 for key management, encryption/decryption and providing integrity service. After that those algorithms are integrated into Message Passing Interface Chameleon version 2 (MPICH2) that becomes ES-MPICH2. It supports a large collection of calculation and conversation area. The proposed work is based on both mathematics and cryptography concept that direct to error free message passing among the authorized users with enhanced security.
