在集群中，节点是通过共享网络相互连接的。随着群集的日益普及在可以访问Internet的广泛网络中，人们对群集上运行程序的安全性的威胁令人震惊。我们正在使用消息传递接口，因为它是一个被广泛接受的并行计算协议。这里考虑的版本是mpich2。如ECC-MPICH2，ES-MPICH2和MPISEC I/O等中的群集通信的方法。本文主要参考CKMS-MPI的工作和模型，并试图进一步提高其安全性。新颖性是增强集中式密钥管理系统的数据安全性。这是通过在ECC中引入滚动曲线方法来实现的，每次用于数据传输的曲线都会不断变化。这将确保数据传输的更高安全性，因为每次都会使用新曲线。附录是为每个节点具有单独的曲线集，以确保即使一个节点受到损害，仍然可以保留其他节点。由于上述机制将纳入同一集中式密钥管理系统（CKMS-MPI），因此性能影响最小，因为仅涉及启动开销。总而言之，我们提出了一种更复杂的滚动曲线机制，用于使用ECC处理集中式密钥管理。
In a cluster the nodes are connected via a shared network to each other. With the increasing popularity of clusters being deployed over widespread networks that have access to internet, there is an alarming increase in threats to security of programs running on the clusters. We are using Message Passing Interface as it is a widely accepted protocol for parallel computing. The version being considered here is MPICH2. There are approaches already available to secure the cluster communication as in ECC-MPICH2, ES-MPICH2, and MPISec I/O etc. This paper primarily references the work and model of CKMS-MPI and tries to further improve its security. The novelty is enhancing data security of the centralized key management system. This is achieved by introducing a rolling curve methodology in ECC where by each time the curve used for transmission of data will keep changing. This will ensure higher security in data transfer because each time a new curve will be used. Addendum is to have separate set of curves for each node to ensure even if one node is compromised the other nodes can still be kept secured. Since the above mechanism will be incorporated into the same Centralized Key Management System (CKMS-MPI) the performance impact is minimum as there is only a startup overhead involved. To summarize, we are proposing a more sophisticated Rolling curve mechanism for key management infrastructure to handle the Centralized Key Management using ECC.
