Most public key cryptosystems used in practice are
based on integer factorization or discrete
logarithms (in finite fields or elliptic curves).
However, if large enough quantum computers can
be built, Shor’s algorithm will render them
completely insecure. Multivariate public key
cryptosystems (MPKC) are one possible
alternative. MPKC makes use of the fact that
solving multivariate polynomial systems over a
finite field is an NP-complete problem, for which it
is not known whether there is a polynomial
algorithm on quantum computers. In this talk, we
give a brief introduction to the area, and we
propose a new multivariate public key encryption
scheme based on Diophantine equations.
