T. Beth (Ed.): Cryptography EUROCRYPT ’82 LNCS 149 pp. 1 28 1983. 0 Springer Verlag Berlin Heidelberg 1983 3 Having all of a sudden left the shady corner of semi military art modern cryptography has become a central topic of research in all areas of communication science. Definitions (cf. Bauer pp. 31 48) Cryptographic measures are applied to p tect valuable data during transmission against unwanted interception INTERCEPTOR Fig. A: passive violation and (possibly undectable) forgery . Fig. 2: acti se violation In accordance with the subsequent paper of Bauer (pp. 31 481 the technique applied to meet these requirements is called en tion. In this process the transmitter enciphers (or encrypts) a plaintext message into a ciphertext. 4 ciphertexc ciphering Fig. 3: The Wire tap channel This transformation is called a cipher(function) which the au rized receiver deciphers (decrypts). An enemy is a person or institution who wants illegal access to the messages. Assuming that the enemy can only get hold of the ciph texts he has to perform a cryptanalysis in order to reconstitute the plaintexts. To add to the difficulties for a cryptanalyst the cipher functions are chosen to a varying parameter called the key. A generator cryptosystem consists of a class of injective cipher functions ES:M C mapping plaintext messages(EM) into ciphertexts(EC) . The parameter s runs through the set K of keys. These formulations are best demonstrated by the basic classical examples.
