Introduction,o a receiver referred to as .. She uses an insecure communication channel. For example, the channel could be a computer network or a telephone line. There is a problem if the message contains confidential information. The message could be intercepted and read by an eavesdropper. Or even worse, the a

Symmetric-Key Encryption,et any significant information about its content. In this chapter, we give a short introduction to symmetric-key encryption. We explain the notions of stream and block ciphers. The operation modes of block ciphers are studied and, as a prominent example for block ciphers, the DES is described.

Provably Secure Encryption,he security of cryptographic schemes and randomness are closely related. An encryption method provides secrecy only if the ciphertexts appear sufficiently random to the adversary. Therefore, probabilistic encryption algorithms are required. The pioneering work of Shannon on provable security, based
