Cryptographic Algorithms with Data Shorter than the Encryption Key, Based on LZW and Huffman Coding

Modern, commonly used cryptosystems based on encryption keys require that the length of the stream of encrypted data is approximately the length of the key or longer. In practice, this approach unnecessarily complicates strong encryption of very short messages commonly used for example in ultra-low-...
