Techniques for securing communication. The techniques include using at least one device to perform method for encrypting input data using a cipher associated with a plurality of languages including a first language, the first language associated with a first set of ciphertext symbols, a first permutation for the first set, and a first partition for the first permutation. The method includes obtaining, from the input data, a first plaintext symbol; mapping the first plaintext symbol to a first ciphertext symbol using the cipher, the mapping including: identifying a first set of candidate ciphertext symbols using the first plaintext symbol, the first permutation, and the first partition; and identifying, at random, the first ciphertext symbol from the first set of candidate ciphertext symbols; and outputting the first ciphertext symbol.
