Multivariate public key cryptography with polynomial composition
Abstract
This paper presents a new public key cryptography scheme using multivariate polynomials over a finite field. Each multivariate polynomial from the public key is obtained by secretly and repeatedly composing affine transformations with series of quadratic polynomials (in a single variable). The main drawback of this scheme is the length of the public key.
