Strategy reasons

codex-llm
confidence 0.98
This round uses zero-hint hierarchical authentication encryption and metadata convergence to simultaneously compress three types of attack surfaces: weak algorithms, metadata leakage, and public hints.
Keep key_disclosure=none and enable round-by-round independent key rotation, stacking three layers of authentication encapsulation and a high number of decoy ciphertexts to increase search and verification costs.
If the random source is degraded, nonce management is incorrect, or the residual length and time characteristics of the packaging process are compromised, attackers may still use implementation flaws to reduce cracking costs.

confidence 0.98
This round adopts zero key disclosure, round-by-step key exchange and metadata minimization, prioritizing the compression of weak algorithms, metadata leaks and public reminder attack surfaces.
Use three-layer authentication encryption and add high-similarity decoy ciphertext to simultaneously increase search and verification costs without providing any key prompts.
If the random source degrades, nonce management fails, or the length and time characteristics of the packaging process are leaked, attackers may still use implementation flaws to reduce cracking costs.
