A matrix key distribution system

Li Gong, David J. Wheeler

DOI: 10.48456/tr-164


A new key distribution scheme is presented. It is based on the distinctive idea that lets each node have a set of keys of which it shares a distinct subset with every other node. This has the advantage that the numbers of keys that must be distributed and maintained are reduced by a square root factor; moreover, two nodes can start conversation with virtually no delay. Two versions of the scheme are given. Their performance and security analysis shows it is a practical solution to some key distribution problems.
