dc.description.abstract | In this thesis, it is shown how the use of bilinear pairings leads to cryptosystems that
provide new functionality.
The Tripartite Diffie Hellman Protocol is implemented; this is a protocol for the establishment
ok keys between parties who have not had a previous contact, using an
insecure channel in an anonymous (unauthenticated) way. This protocol was named
after its creators, who proposed it in 1976 [11].
Generally, the Diffie-Hellman protocol It is used to exchange symmetric keys that will
be used as an example for encrypting a session (i.e. to establish the session key).
Although this is an unauthenticated protocol, it provides the foundation for several
authenticated protocols .
The security of this protocol resides in the extreme difficulty (conjectured, not proven)
to compute discrete logarithms over finite fields.
The version of the Diffie-Hellman protocol implemented in this thesis was developed
by Joux [20] and it uses bilinear pairings and elliptic curves, allowing three participants
to share keys in a single step comunication.
For the developed implementation, GMP libraries were used for handling large numbers,
while PBC libray was used to manage bilinear pairings. | |
