A Ciphertext as a Deterrent

Elastic encryption ciphertexts deter cryptanalysts from cracking them. New feature in the on going cyber war. An elastic ciphertext packs together the real message with an untold number of decoys (fake messages). If a hacker hammers out of the ciphertext one of the decoy messages and is guided by its content to some action then by this very action the cryptanalyst indicates that they cracked the code. And if the underlying cipher is a NIST recommended PQC cipher, then it will become known that this recommended cipher has failed. A fact that the cryptanalyst tries to keep secret with extreme diligence.
It is therefore that cryptanalysts who silently crack a NIST-recommended cipher will shy away from an elastic ciphertext. In other words, the elastic ciphertext acts like a deterrent: don't touch me!
