Abstract
A secure voice solution for a PDA-type device is provided. Voice data is received from the user using the device microphone and built- in media player software in the device. This data is encrypted and sent as an IP packet. The device then receives, as IP packets, encrypted voice communication from the other party in the encrypted call, which in turn are decrypted in the device and played back on a second media player running on the device. The present invention takes advantage of the device's ability to run two media players simultaneously to in effect, simulate a cellular telephone call. As a result, an encrypted call can be made with PDA-type devices such as the Blackberry® and also such calls can be made using different data paths (cellular, WiFi, Bluetooth) as the calls are made by sending and receiving data over the Internet, not as traditional cellular data signals.
