Parallel Algorithm for Hill Cipher on MapReduce

In this paper, a parallel algorithm for Hill Cipher on mapreduce is proposed to reduce the encryption time. As the data in the cloud becomes extensively large, it greatly demands to reduce the encryption time as well as the security storage in the cloud. To address the need, Parallel Modified Hill Cipher is employed to work on mapreduce framework, which is a symmetric encryption scheme and the parallelism is mostly based on the block matrix multiplication. The key matrix is generated to be a self-invertible matrix. The experimental analyses on the cluster demonstrate the effectiveness of the proposed technique.
