ABSTRACT:
Embodiments of a system and method for providing additional security for data being transmitted across a wireless connection that has been established using a known wireless protocol (e.g. Bluetooth) are described. An encryption key is exchanged between a computing device (e.g. a mobile device) and a wireless peripheral device (e.g. a keyboard, a printer). In exemplary embodiments, the encryption key is generated at one of the two devices. Data associated with the encryption key is output at the one device, which can be input by the user at the other device. The encryption key is then recovered at the other device from the input, thereby completing the key exchange. The encryption key can then be used to encrypt and decrypt data transmitted over the established wireless connection, providing additional security.
