Embodiment Construction

[0045] In order to further illustrate the features and advantages of the present invention, the following will be described in detail with reference to the accompanying drawings.

[0046] This embodiment provides a privacy-protected distributed computing method and system for dynamically loading a code base, using an open source distributed cluster Hadoop MapReduce as the underlying system support, and providing a series of security execution components on it. The system is fully compatible with the native MapReduce programming framework. If the user needs to run the job in a privacy-protected manner, it can be achieved by calling the provided API in the code. At the same time, this system also has good portability. By implementing the corresponding computing interface, it can also be applied to other clusters, such as Apache Spark and Storm.

[0047] Before using this system, the system needs to be deployed. In addition to following the deployment method of the original Had...

Abstract

The invention discloses a privacy protection distributed computing method and system for dynamically loading a code library. The invention relates to the field of cloud platform distributed computingand cloud user privacy protection. The confidentiality of data, job codes and a code library depended by a cluster of the cloud platform during job execution is protected; therefore, a malicious cloudinternal attacker cannot obtain and tamper the code and input data of the user in the job execution process; privacy information of a user in the cloud computing process is guaranteed, various attacks mentioned above can be successfully resisted, frequent page exchange and on-demand dynamic code library loading in the task execution process are avoided by introducing verifiable secret sharing andan inadvertent transmission protocol, and minimization of a trusted area is guaranteed.

Description

technical field [0001] The invention relates to the field of cloud platform distributed computing and cloud user privacy protection, specifically a distributed computing that is applied on the cloud platform, allows dynamic tasks to load the required code library, and protects the confidentiality of user data and codes during job execution. methods and systems. Background technique [0002] Cloud computing is currently a mainstream method for processing massive data. Users deploy distributed systems, namely clusters, by renting resources provided by cloud service providers, and upload input data to the cloud to execute distributed jobs. After the job is completed, the user downloads the output from the cloud to obtain the result. But in some scenarios, such as online medical treatment or genetic testing, user input data is often private. If it is directly uploaded to the cloud in plain text, it will be obtained by a malicious internal cloud attacker (such as a cloud admin...
