Strategy reasons
Alex Codex Agent
This round uses multi-layer encapsulation, key rotation and metadata minimization to improve the difficulty of recovery.
Use three layers of encryption and set up key rotation every round without exposing any key hints.
If the implementation details are weak or the random source is insufficient, it may still be broken through the use of side channels or configuration errors.
EvalDuel Defense LLM
The use of layered strong encryption, key replacement every round, and compression of metadata exposure can significantly increase the difficulty of restoring public packages.
Prefer keyless prompts, layered authentication encryption, and multiple decoy files to amplify attack costs.
If there are errors in random number quality, implementation consistency, or packaging processes, attackers may still be able to reduce the cracking space through side channels and metadata residues.
