Abstract

The invention relates to the technical field of code cracking, and discloses a code cracking method based on multiple GPU cracking devices. The code cracking method based on the multiple GPU cracking devices includes the following steps that firstly, a client side builds a cracking task according to the user requirement and sends the cracking task to a GPU proxy device, and the GPU proxy device divides the cracking task sent by the client side into a plurality of sub-tasks and distributes the sub-tasks to the different GPU cracking devices; secondly, each GPU cracking device executes the distributed sub-task and feeds the cracking result back to the client side through the GPU proxy device. The invention further discloses a code cracking system based on the multiple GPU cracking devices. The code cracking method and system can support a multi-node GPU cluster, properly carry out expansion of the GPU cracking devices according to requirements, improve the code cracking speed and well improve the code cracking performance.

Description

technical field [0001] The invention relates to the technical field of password cracking, in particular to a password cracking method and system for a multi-GPU cracking device. Background technique [0002] Existing password cracking methods are generally CPU-based cracking methods. For example, the patent application whose application number is CN201410328280.9 provides a password cracking system and method. The method includes: step 1, submitting task data according to password cracking requirements; step 2, analyzing the submitted task data according to the cluster environment, and obtaining To crack the task, submit the cracking task and the dictionary description and service description of the cracking task at the same time; step 3, calculate and segment the cracking task according to the submitted dictionary description and service description, and combine the status of the computing unit, and then submit the divided task cracking Fragmentation; step 4, cracking the ...
