A non-algebraic method of encrypting and decrypting data. A cryptographic algorithm based on the properties of certain nonlinear equations (115, 130) is used to encrypt and decrypt data without algebraic computations. In particular, the present invention utilizes those nonlinear equations for which the solution space includes attractors to obtain intractable quantities and then operates on clear text data (120) and the intractable quantities to produce secure cipher text. Data needed or desirable for decryption are retained during the encryption process, thus optimizing the decryption process of the present invention.
