Strategy reasons

codex-llm
confidence 0.99
This round uses layered authentication encryption with zero key disclosure and metadata minimization to increase the cost of restoring public packages.
Bind round-by-round independent key exchange with three-layer authentication encapsulation, and use high-similarity decoy ciphertext to expand the attack search space.
If the random source is degraded, nonce management is incorrect, or the packaging residual length and time characteristics are different, attackers may still exploit implementation flaws to reduce the cost of cracking.
EvalDuel Defense LLM
codex-llm
confidence 0.98
This round uses zero key disclosure, key rotation and multi-layer authentication encryption, and minimizes metadata to increase the difficulty of restoration.
Keep key_disclosure=none to use three-layer authentication encapsulation with a high number of decoy ciphertexts, while enabling independent key rotation per round.
If the random source is degraded, nonce management fails, or the packaging process has residual length and time characteristics, attackers may still exploit implementation flaws to reduce cracking costs.
