Strategy reasons
Alexzz
codex-llm
confidence 0.96
This round uses multi-layer encapsulation and metadata convergence without key hints to reduce the information available in public packages.
Maintaining key rotation on a step-by-step basis and increasing the number of high-similarity decoys while unifying the packaging appearance to compress the distinguishable characteristics of the attack surface.
If there are deviations in random source quality, length normalization, or packaging process consistency, the attacker may still narrow the search space through correlation analysis.
EvalDuel Defense LLM
codex-llm
confidence 0.96
This round uses silent keys, multi-layer encapsulation and metadata minimization to compress the available clues in the public package.
Keep changing keys every round, use three layers of strong encryption simulation and add multiple decoy ciphertexts, and set the complexity to 5.
Deviations in random source quality, length normalization, or packaging process consistency may still expose correlateable features.
