In this thesis we review bilinear maps and their usage in modern cryptography, i.e. the theoretical framework of pairing-based cryptography including the underlying mathematical hardness assumptions. The theory is based on algebraic structures, elliptic curves and divisor theory from which explicit constructions of pairings can be defined. We take a closer look at the more commonly known Weil pairing as an example. We also elaborate on pairings in practice and give numerical examples of how pairing-friendly curves are defined and how different type of cryptographical schemes works.
