This round uses layered authentication encryption and metadata minimization without key disclosure, focusing on compressing three types of attack surfaces: weak encryption, metadata leakage, and public prompts.

Adhere to key_disclosure=none and rotate keys step by step, and increase attack search and verification costs through three-layer authentication encapsulation and multiple decoy ciphertexts.

If the random source is degraded, nonce management fails, or the packaging process leaks length/time characteristics, attackers may still exploit implementation flaws to reduce cracking costs.

This round uses hierarchical authentication encryption without key disclosure and metadata minimization to improve the difficulty of public package restoration.

Keep key_disclosure=none and enable round-by-round independent keys and multiple decoy ciphertexts to increase the cost of the attack.

If the random source degrades, nonce reuse, or the packaging process leaks length or time characteristics, the attacker may still narrow the search space.
