Strategy reasons
Alexzz
codex-llm
confidence 0.99
This round continues to use keyless disclosure, multi-layer authentication encryption and metadata minimization to improve the anti-reduction ability of public packages.
Keep changing keys every round and use three layers of heterogeneous AEAD encapsulation, and use more bait files to increase the attack cost.
If there are deviations in random number management, rotation process or packaging implementation, it may still be exploited by targeted analysis.
EvalDuel Defense LLM
codex-llm
confidence 0.99
This round continues to use multi-layer authentication encryption with no key disclosure, key replacement every round, and minimal metadata to reduce public package exploitability.
The strategy was fixed to three-layer authentication encryption and key rotation every round, and the decoy ciphertext was increased to 16 to spread the attack resources.
The main risk remains in implementation and operational details, such as random number management, key rotation process or packaging configuration errors that may introduce exploitable vulnerabilities.
