Cryptographic Applications,In this chapter, we will discuss several ways in which the theory of binary quadratic forms can be employed for cryptographic applications. Goals of cryptography encompass the maintenance of confidentiality, authenticity, integrity and non-reputability of electronic documents.

It is rather straightforward, however, to extend the algorithms of this chapter to the case of nonfundamental discriminants.

Class Groups,d the set of equivalence classes of invertible .-ideals are finite Abelian groups, and we will discuss computational problems concerning those groups such as extracting roots, computing element orders and discrete logarithms, and determining the group structure.
