Overview

Randomized trial develops lightweight S-boxes with low hardware complexity in cryptographic systems, suggesting improved security.

Key Points

  • This research aims to design lightweight yet secure 6-bit and 12-bit S-boxes with low hardware requirements.
  • Developed three 6-bit S-boxes and six 12-bit S-boxes using combinations of small S-boxes and XOR operations.
  • Emphasized minimizing logic gates while ensuring adequate security levels in the designs.
  • Presented hardware results and security analyses for comparison with existing structures.
  • Achieved a maximum nonlinearity of 24 for 6-bit S-boxes and 1888 for 12-bit S-boxes.
  • Optimal S-box structures were developed, demonstrating lower gate counts and improved security compared to existing designs.
  • Proposed S-boxes are viable candidates for implementation in block ciphers.
