DES, (see Figure 6.1). Although the keysize is 64, the effective keysize is 56 bits. The remaining 8 bits are parity checks. The input . and key . result in a ciphertext ., which we shall denote by DES(.). For the decryption the same DES chip with the same key can be used, as we shall see later.

Private Lebensformen im Wandel,the set {0,1,…,.-1} and . . .. For most practical alphabet sizes the cryp-tanalist can break this system easily by trying all q possible keys. This is called .. For instance, when . = 26 and we use {a,b,..., z} as alphabet, one only has to check 26 possibilities. In Table 2.1 one can find the cryptanalysis of the ciphertext IYBABZ.
