  Homomorphic encryption is a method used in cryptopgraphy to create programs
that can interact with encrypted data without ever leaving the data in the
clear. This has many potential applications in cybersecurity. This paper uses
automorphisms of affine space to create a form of homomorphic encryption for
straight line programs. The encryption method used for the data is known as
multivariate encryption. This gives a potentially powerful new method in cyber
security based on techniques from algebraic geometry.
