Abstract: A data processing system, method, and product are disclosed for securing radio transmissions utilizing a conventional radio. A conventional radio and a computer system are provided. The computer system is separate and apart from the conventional radio. The conventional radio is capable of receiving an input analog signal from a microphone and then transmitting the input analog signal. The conventional radio is incapable of encrypting the input analog signal. The computer system is coupled between the microphone and the radio such that inputs into the microphone are received first by the computer system. The computer system receives an input from the microphone, encrypts the input utilizing public key encryption, and passes the encrypted input to the radio. The radio then transmits the encrypted input. Thus, radio transmissions from the conventional radio are secured.

Abstract: The present invention is a data processing apparatus and method for encrypting, sending, receiving, and decrypting secure transmissions using a cellular telephone. The user may either purchase a cellular telephone which contains the encryption and decryption software, download the encryption and decryption software to an existing cellular telephone, or may purchase an encryption component which is adaptable to a conventional cellular telephone. Additionally, the described system of encryption and decryption can be used for secure communications in PDA/cellular telephones combinations and any other type of portable communications device. The encryption process is a Java application which converts the user's audio signal into a wav file. The encryption program then creates a second wav file using the first wav file header. The encryption program then converts the data in the first wav file into encrypted data in the second wav file using public key encryption and a series of data manipulations.
