Query: Multivariate Cryptography with Mappings of Discrete Logarithms and
  Polynomials   In this paper, algorithms for multivariate public key cryptography and
digital signature are described. Plain messages and encrypted messages are
arrays, consisting of elements from a fixed finite ring or field. The
encryption and decryption algorithms are based on multivariate mappings. The
security of the private key depends on the difficulty of solving a system of
parametric simultaneous multivariate equations involving polynomial or
exponential mappings. The method is a general purpose utility for most data
encryption, digital certificate or digital signature applications.
