Keywords:

We present a probabilistic public key cryptosystem which is

secure unless the following worst-case lattice problem can be solved in

polynomial time:

"Find the shortest nonzero vector in an n dimensional lattice

L where the shortest vector v is unique in the sense that any other

vector whose length is at most a constant power of n times the length

of v, is parallel to v ."

Shai Halevi has pointed out an error in the proof of

Lemma 3.1 in the first version of the paper. In the revised (second)

version we present a corrected proof.
