Abstract:
|
The ability to communicate securely is needed for many network
applications. Public key infrastructure (PKI) is the most extended
solution to verify and confirm the identity of each party involved in any
secure transaction and transfer trust over the network. One of the hardest
tasks of a certification infrastructure is to manage revocation. Research
on this topic has focused on the trade-offs that different revocation mechanisms
offer. However, less effort has been paid to understand the benefits
of improving the revocation policies. In this paper, we analyze the
behavior of the oligopoly of certificate providers that issue digital certificates
to clients facing identical independent risks. We found the prices in
the equilibrium, and we proof that certificate providers that offer better
revocation information are able to impose higher prices to their certificates
without sacrificing market share in favor of the other oligarchs. In
addition, we show that our model is able to explain the actual tendency
of the SSL market where providers with worst QoS are suffering loses. |
