Strategy reasons

codex-llm
confidence 0.98
This round uses three-layer authentication encryption without key disclosure, key replacement every round and metadata minimization to improve the anti-reduction ability of the public package.
Keep key_disclosure as none and enable key exchange every round. Use three layers of encapsulation and 14 decoy ciphertexts to increase the attack cost.
The main risk is errors in implementation and operation details, such as random number management, rotation process, or package configuration deviations that lead to exploitable vulnerabilities.
EvalDuel Defense LLM
codex-llm
confidence 0.99
This round uses no key disclosure, key exchange every round and multi-layer authentication encryption, and minimizes metadata exposure.
Choose three-layer authentication encryption, rotating keys and 14 decoy files to prioritize reducing the risk of metadata leakage and public prompts.
The main risk lies in errors in implementation and operation and maintenance details, such as random number reuse, rotation process deviations, or decoy distribution anomalies that are exploited by targeted analysis.
