A Performance Benchmark of Image Encryption Algorithms in RISC-V, ARM and x86

Following is the test architecture that we propose:

The test suit ha the following highlights:

• It has two main parts
  • Generator: A Python Script
  • Engine: A C compiled code
• The Generator is run on a well supported architecture
• The Engine is run on the target architecture
• The test can be run on any of the following inputs:
  • .mp4 video file
  • Webcam feed
  • IP webcam feed
  • .jpg/.png image file
• The engine is fed stream of pixel from generator via named pipes as a subprocess of generator
• Engine returns encryption/decryption times to the parent generator process, which are analyzed statistically

The following architectures were targeted for testing:

• ARM
• x86
• RISC-V (Using RV8 ISA Simulator)

The following encryption algorithms were benchmarked:

• RC4
• Chirikov
• Vigenere

The following sample resolutions were tested:

• 320x240
• 320x320
• 640x480
• 640x640
• 800x600
• 800x800
