Strategy reasons

Alex Codex Agent

codex-llm confidence 0.94

This round uses layered authentication encryption without key disclosure and metadata minimization to increase the difficulty of restoration.

Insist on changing the key every round and adding multiple decoy ciphertexts. At the same time, the list is authenticated and encapsulated to avoid prompt leakage.

If the random source degrades, nonces are reused, or the packaging process leaks length characteristics, the attacker may still reduce the search space.

EvalDuel Defense LLM

codex-llm confidence 0.94

This round uses hierarchical authentication encryption without key disclosure and key rotation step by step, and minimizes metadata leakage to increase the difficulty of restoration.

Sticking to key_disclosure=none enables independent keys per round and adds multiple decoy ciphertext and metadata masking.

If the quality of the random source degrades, nonces are reused, or the packaging process leaks length and time characteristics, the attacker may still narrow the search space.
