Lattice cryptography is a post quantum cryptography that work on two NP-hard problem in below:
Find shortest nonzero vector from origin and
Find minimum distance of a arbitrary point out of lattice from origin.
At the moment lattice cryptography system is broken with key space of dimension 300. On the other hand we use dimension 400 in this cryptosystem. Can we use this cryptosystem in future?
How we can distinguish between this cryptosystem with others?
