Password attacking method and apparatus, and heterogeneous acceleration platform

Abstract

The invention discloses a password attacking method and apparatus, and a heterogeneous acceleration platform. The method is applied to the heterogeneous platform including a CPU terminal and an FPGA terminal. The method comprises the following steps: the FPGA terminal reads a pre-stored rainbow table and to-be-attacked ciphertext data; the FPGA terminal performs parallel processing on the to-be-attacked ciphertext data according to a preset password attacking algorithm to obtain to-be-selected password data; the FPGA terminal performs matching on the to-be-selected password data and the rainbow table according to a preset matching algorithm to find out an alternative password; and the FPGA terminal returns a completion signal to the CPU terminal. Therefore, according to the password attacking method and apparatus, and the heterogeneous acceleration platform, the FPGA is utilized to perform hardware acceleration of the password attacking algorithm, and the FPGA performs the password attacking algorithm in parallel, so the parallelism of the algorithm is improved, the throughput rate performance when the algorithm is executed is improved, and thus the performance of the password attacking algorithm based on the rainbow table is improved; and furthermore, the redundant fine graining of the FPGA terminal is parallel, so the hardware cost is relatively low.

Description

technical field [0001] The invention relates to the technical field of reconfigurable computing, in particular to an attack method, device and heterogeneous acceleration platform. Background technique [0002] With the rapid increase of data volume in the information age, the privacy and security of information and data seriously affect people's life and work. Password authentication is a widely used identity authentication and system protection method at present. [0003] Passwords generally include passwords and keys. In specific applications, defects such as too short passwords and single characters can easily lead to security vulnerabilities. Keys and passwords are often the main targets of rainbow table attacks. [0004] In order to protect the security of information system and user identity authentication, the system needs to identify weak passwords and mark them. At present, there are performance bottlenecks in theoretical algorithms and programs when identifying ...
