Ciphers

  • Asymmetric Key (PKE)
    • Textbook RSA
    • DGVH
  • Symmetric key
    • AES
    • Modified vulnerable version of AES - AES without shift rows
    • Geffe stream cipher

Attacks

The following attacks are on know plain text attacks.

  • Double encryption attack on AES
  • Key recovery on the modified version of AES
  • Divide and conquer attack on Geffe stream cipher
  • Correlation power analysis on AES

Usage examples are provided in the attacks source code files
