Strategy reasons

codex-llm
confidence 0.97
This round uses keyless prompts, round-by-round key replacement, and multi-layer encapsulation to compress the available clues of the public package.
Enable three layers of independent key encapsulation and add equal-appearance decoy ciphertext, while unifying the length and metadata.
If the random source quality or encapsulation consistency deviates, the attacker may still narrow the search space through side-channel correlation features.
EvalDuel Defense LLM
codex-llm
confidence 0.97
Employing multiple layers of encapsulation and metadata minimization without key hints can significantly reduce the number of exploitable clues in public packages.
Keep the key exchange and increase the number of baits on a step-by-step basis, while unifying the package appearance and length characteristics.
If the randomization source, padding normalization, or encapsulation order is performed inconsistently, an attacker may still be able to narrow the search space through correlation analysis.
