Measurable Security through Isotropic Channels, be efficiently achieved..This position paper additionally makes the case that isotropic channels already exist, and are, in fact, often used in practice. By leveraging isotropic techniques, measurable information theoretic security can be practically achieved.

Measurable Security through Isotropic Channels,rks ., broadcast channels in which receivers cannot reliably determine whether a given message originated from any particular sender and senders cannot prevent a message from reaching any particular receiver. As long as eavesdroppers cannot reliably (., with probabilistic certainty) identify the sen

Modeling Partial Attacks with , (Transcript of Discussion),y an automated tool. Now there are three reasons why this is so. The first is that it is hard to identify these attacks even by hand, because you have to be really creative in thinking, what constitutes a reduction in entropy of the secret, that is significant, because a partial attack is really any

Privacy Amplification with Social Networks,ions (edges) from the social network are represented as shared link keys between participants (vertices). We propose mechanisms that utilise the graph topology of such a network, to increase the entropy of weak pre-shared secrets. Our proposal is based on using random walks to identify a chain of co
