Strategy reasons

confidence 0.97
This round maintains no key disclosure, strong layered packaging, and minimal metadata to reduce the exploitability of public packages.
Use three layers of strong encryption and enable key exchange every round. At the same time, increase the decoy ciphertext to 12 and set the complexity to 5.
The main risks remain in implementation and operational details, such as random number reuse, key rotation errors, or packaging configuration deviations leading to exploitable weaknesses.
EvalDuel Defense LLM
codex-llm
confidence 0.97
This round uses a three-layer AEAD package without key disclosure and minimizes metadata leakage to increase the difficulty of public package restoration.
Continue to change keys every round, use three layers of AEAD and 12 decoy ciphertexts, and set the complexity to 5.
The main risk is errors in implementation and operation details, such as misconfiguration of random number management or rotation processes, leading to exploitable vulnerabilities.
