Summary:
In this thesis, we initially provide a general introduction to pairing-based
cryptography, consisting of the presentation of the established methods for
constructing and computing a pairing and some of the most fundamental
pairing-based schemes and protocols. We then focus on the analysis of the
seminal Groth-Sahai system for the construction of efficient non-interactive
NIWI and NIZK proofs. Finally, we examine
the applications of the Groth-Sahai proof system to group signature schemes and
especially their contribution to achieving the required security properties
without random oracles.
