Abstract
A system and method for encoding and decoding radio frequency (RF) signals between a computer and an RF peripheral device. Because information communicated between a computer and an RF peripheral device may be sensitive, e.g., contain passwords or credit card numbers, RF signals may be encoded and decoded by the computer and/or RF peripheral device before transmission between the computer and RF peripheral device to preserve the security of the information. The computer may transmit a key register to the RF peripheral device that may be used to encode RF signals sent to the computer or decode RF signals received by the computer. The key registers may be changed as needed. The RF signals may contain encoded and unencoded sections.
