WebDec 21, 2014 · 3. The definition of an unconditionally secure cryptosystem states that the cryptosystem cannot be broken even with infinitely computational ressources and time. However, since most books define the keyspace K to be finite, then with infinite time any computational device can perform an exhaustive keysearch. WebA block cipher cryptosystem consists of two algorithms: an encryption algorithm and a decryption algorithm. The encryption algorithm takes as input an n-bit message m and a k-bit key K and outputs an n-bit ciphertext C; the decryption algorithm takes as input an n-bit ciphertext C and a k-bit key K and outputs an n-bit message m. churches in tenby pembrokeshire
