On the Security Properties of e-Voting Bulletin Boards
bulletin board e-voting, liveness persistence
2018/6/6
In state-of-the-art e-voting systems, a bulletin board (BB) is a critical component for preserving election integrity and availability. Although it is common in the literature to assume that a BB is a...
In cryptography, forward secrecy is a well-known property for
key agreement protocols. It ensures that a session key will remain private
even if one of the long-term secret keys is compromised in th...
Security properties of two authenticated conference key agreement protocols
Security properties authenticated conference key agreement protocol insider attacks
2009/2/12
In this paper we analyse the security of two authenticated group key agreement
schemes based on the group key agreement protocol of Burmester
and Desmedt. One scheme was proposed by Burmester and De...
A Cryptographic Model for Branching Time Security Properties – the Case of Contract Signing Protocols
Cryptographic Model Branching Time Security Properties Contract Signing Protocols
2008/8/19
Some cryptographic tasks, such as contract signing and other related tasks, need to ensure complex,branching time security properties. When dening such properties one needs to deal with subtle proble...
