Wired on Navy's new version of Onion Routing

[Sarad AV]

hi,

Since they are using symmetric keys, for a network of
'n' nodes, each node  need to know the secret key that
they share with the remaining (n-1) nodes.Total number
of symmetric keys that need to be distributed is
[n*(n-1)]/2. Key management is harder when they
network gets larger.
