A cryptographic attack method, device and heterogeneous acceleration platform

Abstract

The invention discloses a password attack method, device and heterogeneous acceleration platform. The method is applied to a heterogeneous platform including a CPU end and an FPGA end, including: the FPGA end reads a pre-stored rainbow table and ciphertext data to be attacked; According to the preset password attack algorithm, the ciphertext data to be attacked is processed in parallel to obtain the password data to be selected; the FPGA side matches the password data to be selected with the rainbow table according to the preset matching algorithm to find out the candidate password; The terminal returns a completion signal to the CPU terminal. It can be seen that this application utilizes FPGA to perform hardware acceleration of the cryptographic attack algorithm, and the FPGA executes the cryptographic attack algorithm in parallel, which improves the parallelism of the algorithm, improves the throughput performance of the algorithm execution, and then improves the performance of the cryptographic attack algorithm based on the rainbow table . Furthermore, the redundancy and fine-grained parallelism at the FPGA side make the hardware cost lower.

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 ...
