This thesis is concerned with applying software Engineering techniques to
pairing based cryptographic systems. In particular we evolve our existing
cryptographic system to incorporate new cryptographic concepts that
strengthen the system. We discuss the design approach taken to allow an
advanced mathematically based cryptographic concept to be developed in a
maintainable manner. We present the integration process and evolutionary
impacts on the existing system. We provide some testing data on the resulting
system and give an indication of its performance. The language chosen is
Java and the objective is that the Java developer can easily use the resulting
system with minimal knowledge of the underlying machinery. Specifically,
we present, implement, and evaluate alternative approaches to the use of a
standard implementation of Tate pairing in a Java-based biometric identity
verification tool
