Abstract(in English) | Extensive studies have been made on the public-key cryptosystems that are constructed based on multivariate polynomials. However in most of the conventional cryptosystems are proved not secure against the algebraic attacks. Recently, the public-key cryptosystems based on random multivariate polynomials have been proposed. In this paper, we analyze the public key cryptosystems that are constructed based on random polynomials over 2 variables. We then show that the cryptosystems are insecure. |
