The Advanced Encryption Standard (AES),lock cipher is also mandatory in several industry standards and is used in many commercial systems. Among the commercial standards that include AES are the Internet security standard IPsec, TLS, the Wi-Fi encryption standard IEEE 802.11i, the secure shell network protocol SSH (Secure Shell), the Int

More About Block Ciphers,mechanisms can be realized. For instance, we can use them for building different types of blockbased encryption schemes, and we can even use block ciphers for realizing stream ciphers. The different ways of encryption are called . and are discussed in this chapter. Block ciphers can also be used for

The RSA Cryptosystem,opened up. As a consequence, cryptologists started looking for methods with which public-key encryption could be realized. In 1977, Ronald Rivest, Adi Shamir and Leonard Adleman (cf. Fig. 1) proposed a scheme which became the most widely used asymmetric cryptographic scheme, RSA.

Message Authentication Codes (MACs),s, since they also provide message integrity and message authentication. However, unlike digital signatures, MACs are symmetric-key schemes and they do not provide nonrepudiation. One advantage of MACs is that they are much faster than digital signatures since they are based on either block ciphers

Hash Functions,manifold: Hash functions are an essential part of digital signature schemes and message authentication codes, as discussed in Chapter 12. Hash functions are also widely used for other cryptographic applications, e.g., for storing of password hashes or key derivation.
