Abstract
A cryptographic communication method comprises a step for carrying out cryptographic communication between a sending station and one or more receiving stations by using (1) a ciphertext formed by encrypting a unit of sending information under the intervention of at least a cryptographic key and (2) key-distribution-information produced by using at least the ciphertext, receiving station's public information, and randomized information generated in the sending station.
