Abstract or Summary:
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 generated is proportional to the number of nodes. Moreover, two nodes can start a session with virtually no delay. The scheme suits an environment where there is a certain level of trust among the insiders. The security property to an outsider remains identical to that of other existing schemes. Two versions of the scheme are given. Analysis of security and performance shows it is a practical solution to some key-distribution problems.
