Manipulative attack using the phase retrieval algorithm for double random phase encoding.

Area of Science:

• Cryptography
• Information Security
• Signal Processing

Background:

• Secure communication systems are vulnerable to sophisticated attacks.
• Existing cryptanalysis methods often rely on specific, limiting assumptions.
• Phase retrieval algorithms offer new avenues for information extraction.

Purpose of the Study:

• To propose a novel attack scheme for cryptosystems based on phase retrieval.
• To demonstrate an attack that bypasses traditional assumptions.
• To validate the scheme's effectiveness using a practical example.

Main Methods:

• Developing an attack strategy leveraging phase retrieval principles.
• Implementing ciphertext falsification and information gathering techniques.
• Testing the scheme against a double random phase encoding system.

Main Results:

• The proposed attack scheme successfully intercepted and cracked the system.
