Integers,Integers play a fundamental role in cryptography. In this chapter we present important properties of integers and describe fundamental algorithms. Efficient Implementations of the algorithms described in this chapter can, for example, be found in the C+ + library LiDIA [46].

Discrete Logarithms,In this chapter, we discuss the difficulty of the discrete logarithm problem (DL problem). The security of many public-key cryptosystems is based on the difficulty of this problem. An example is the ElGamal cryptosystem (see Section 8.6).

Cryptographic Hash Functions,In this chapter, we discuss cryptographic hash functions. They are used, for example, in digital signatures. Throughout this chapter, we assume that Σ is an alphabet.
