Potential Structural Weaknesses

[Akshat1806]

Potential Structural Weaknesses & Cryptanalysis

Objective

Identify structural, mathematical, or implementation weaknesses in the Prime Cipher (PC).

---

Areas of Interest

Cipher Structure

• Layer separability
• Deterministic weaknesses
• Weak diffusion
• Weak avalanche effect
• Classical transposition vulnerabilities

---

Mathematical Weaknesses

• Affine reduction attacks
• Prime-chain predictability
• Grouping reversibility
• Index-collision behavior

---

Implementation Weaknesses

• Padding predictability
• RNG behavior
• Error propagation
• Edge cases

---

Suggested Questions

1. Are the encryption layers cryptographically entangled?
2. Can the cipher be decomposed into independently attackable stages?
3. Does the pivot system create exploitable deterministic behavior?
4. Are there low-entropy edge cases?
5. Can padding be reliably identified and removed?
6. Does the system exhibit meaningful diffusion?
7. Can small-word handling be exploited?
