you are sent only the numbers (t(s)h(s) k) and (w(s)v(s) k)
Who is sending to whom? What does it prove if you are sent two identical numbers? Poor explanation :-(

a secret evaluation point s
only one?
permutes
How is that permuting? Permutation means changing the ordering.
t(s)h(s) = w(s)v(s)
Seems to imply calculation of E(t(s))E(h(s)) etc. using homomorphic properties, but fails to explain that, or even what the homomorphic properties allow.
