Abstract
A method is disclosed for processing a file in either an encryption operation or a decryption operation. A received analog signal is received comprising one of an analog encrypted signal to be decrypted or an analog message signal to be encrypted, each having an associated length from a fixed beginning point. A first analog key signal and a second analog key signal are received, each having a fixed beginning point and an associated length. The received analog signal is processed through a first transfer function and the output of the first transfer function processed through a second transfer function, each of transfer function having at least a second order response. The operation of the first transfer function is parameterized with the first analog key and the operation of the second transfer function is parameterized with the second analog key. The steps of parameterizing are controlled to synchronize the beginning of the one of the encrypted analog encrypted signal or the analog message signal received as the received signal with the beginning of the first and second analog key signals.
