Abstract. Algorithmic progress and future technology threaten today’s cryptographic protocols. Long-term secure protocols should not even in future reveal more information to a...
—In this paper, we formulate and realize a definition of security for three-party key distribution within the universally composable (UC) framework. That is, an appropriate ideal...
The existing unconditional security definitions of quantum key distribution (QKD) do not apply to joint attacks over QKD and the subsequent use of the resulting key. In this paper...
