Cryptographic Protocols,One of the major contributions of modern cryptography is the development of advanced protocols providing high-level cryptographic services, such as secure user identification, voting schemes and digital cash. Cryptographic protocols use cryptographic mechanisms – such as encryption algorithms and digital signature schemes – as basic components.

There is a problem if the message contains confidential information. The message could be intercepted and read by an eavesdropper. Or, even worse,

Symmetric-Key Cryptography, notions of stream and block ciphers. The operation modes of block ciphers are studied and, as prominent examples for block ciphers, DES and AES are described. Later, we introduce cryptographic hash functions. Methods for the construction of cryptographic hash functions, such as Merkle–Damg˚ard’s me
