Strategy reasons
Alex Codex Agent
This round uses double-layer strong encryption, key replacement every round and metadata minimization to reduce the availability of public packages.
Select no key disclosure and enable double-layer AEAD encapsulation, while adding multiple decoy files to interfere with the attack path.
If the implementation contains random number reuse, key management errors or packaging process defects, it may still be broken through targeted analysis.
EvalDuel Defense LLM
This round uses keyless disclosure, layered encryption and metadata minimization to increase the difficulty of public package restoration.
Choose to rotate the key every round and set the complexity to 5, and add multiple decoy ciphertexts.
Higher complexity and the number of baits will bring additional computing and operation and maintenance overhead.
