Design and implementation of distributed RSA algorithm based on Hadoop

With the advent of the era of big data, the deep integration of the Internet and healthcare makes medical data exponential growth. How to ensure data security is particularly important. However, the traditional encryption speed is no longer applicable to massive information processing. Based on Hadoop open source project, this paper designs and studies distributed RSA encryption algorithm based on distributed file system and programming model. In the beginning of this paper, a design scheme of distributed encryption algorithm based on platform is proposed, the distribution of distributed algorithm is determined, module partition and process control are carried out to the whole, and the distributed encryption function of the single computer encryption system is realized. Finally, through the large-scale distributed cluster built in the laboratory, the distributed encryption algorithm is tested by function test, extensibility test and efficiency test. It is proved that the distributed encryption algorithm can optimize the operation speed and can be applied to the processing of massive data.
