On metric-preserving functions and fixed point theorems
... Since f (x) ∈ [, ] for all x > , f is tightly bounded. Therefore by Lemma , f is metric preserving. It is easy to see that f is not increasing (and is not concave either). So f is not a metric transform. It ...

Provably Secure Public-Key Encryption for Length-Preserving Chaumian Mixes
... Usually it is desireable to allow source routing, i.e. let senders choose mix chains on a per-message basis. This increases the flexibility of the whole scheme: senders can make use of new mixes that go into operation, ...
