The research aims to investigate the boundary between classical public key cryptography and any possibilities for quantum public key cryptogra Such an interplay has not really been investigated fully before and the work we plan will benefit both communities. Firstly we aim to build upon schemes as as NTRU which appear to be resistant to quantum computers, secondly we aim to bring into the quantum setting the foundational v provable security of public key protocols. This will then naturally lead on to the study of new complexity theoretic assumptions, the foundational work acting as a guide as to what is required. At present the best available assumptions are those based on lattices, however it is not clear whether tl hardness of the lattice CVP or SVP are gauranteed in a quantum setting and in addition such assumptions are hard to turn into signature scherr to the lack of the zero-knowledge property of all practical lattice based signature schemes currently known.
