This round adopts zero key disclosure, step-by-step key exchange and multi-layer authentication encapsulation, and minimizes metadata exposure to increase the difficulty of restoration.

Keep key_disclosure=none, use three-layer encapsulation and add highly similar decoy ciphertext to simultaneously increase search and verification costs.

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

This round adopts zero key disclosure, round-by-step key exchange and multi-layer authentication encapsulation, and improves the cost of public restoration through metadata convergence and high similarity bait.

Fixed key_disclosure=none, enabling independent key rotation per round, stacking three layers of authentication encapsulation and 8 decoy ciphertexts.

If the random source is degraded, nonce management fails, or the residual length and time characteristics of the packaging process exist, attackers may still exploit implementation flaws to narrow the search space.
