Abstract: Claude Shannon revolutionized cryptography by introducing the unicity distance as the minimum ciphertext required to yield a unique solution to a cryptogram.1 2 3 He proved that this distance is a functionality of the redundancy of the plaintext; that if redundancy is nil, the unicity distance becomes infinite. 2 4 6 The Rapprochement Cipher has an infinite unicity distance by direct application of Shannon’s principles to cryptography, operating on a key of infinite entropy. 2 5 Thr...
