AMPC Election Protocol Over WAP

AMPC Election Protocol Over WAP

• In this presentation we will briefly go through
  the software engineering phases of the system
  implementation.

2
Requirements

• To enable voters to participate in the AMPC
  election protocol using a WAP agent.
• Portability. The implementation was written in
  JAVA.
• Fast deployment.
• Dynamic content. The application parameters can
  change dynamically.
• Transparency. The voter is not aware of the
  algorithm being used by the election protocol.

Why WAP?

• The election protocol doesn't require heavy
  processors either on the side of the AMPC network
  entities or on the side of the voter (there is no
  need for conventional cryptography).
• The natural choice for an end user's device would
  be a WAP agent.

Design

• The system is compromised of three separate,
  though related, entities
• The WAPServer
• Deployed on a web server. Enables a WAP
  browser to download the election protocol
  application, which includes two types of content.
• WML - responsible for the user interface.
  WMLScript - responsible for the ballot
  generation.

Design (Cont)

• The WAP agent
• WAP browser is responsible for displaying and
  interpreting the content sent by the WAPServer.
• The WAP agent could be any third party WAP
  emulator or WAP enabled device. In this demo we
  are using the Openwave WAP emulator.
• The WAPAdapter
• Responsible for forwarding the concealed ballots
  to the AMPC network.
• The WAPAdapter can be seen as a bridge between
  the two networks - the wireless and the wired.

• Voting process
• Voter fills in his identifier and VID.
• Voter selects his candidate.
• The application generates the concealed ballot.
