Abstract

In this paper, we propose an encryption algorithm with anti-symmetric keys. The algorithm is assumed to be known to public, but the keys are kept private. The primary key (at the encryption site) is designed based on matrix transformation with the requirement that all arithmetic operations are strictly over the integer field. Therefore, there are no round off errors when the signal is deciphered at the receiver site. The anti-symmetric key algorithm is designed for constructing such a primary key in the proposed encryption scheme, which is shown to be robust against attacks.
