International Classification:

H04B 7/00

US Classification:

455041200

Abstract:

Disclosed are a unique system and method that facilitate establishing and maintaining a secure connection between at least one wireless input component and a host (e.g., PC). The system and method involve the wireless input component broadcasting a message that can be “heard” by any potential host located within a given distance from the wireless input component. The message can indicate that the input component is available for use or pairing with a PC. PCs in the area can respond to the message by notifying the user that a wireless input component is available and by generating a random PIN. The PIN can be displayed to the user on the respective PC. The user can be prompted to enter the PIN using the wireless device. When a match between the user's response and the corresponding PC is determined, the two can be securely linked. In addition the invention provides support of wireless input devices at boot or start up.

International Classification:

H04B 1/38

US Classification:

455574000

Abstract:

A wireless input device may negotiate a predefined transmit/receive schedule with a receiving device (i.e., PC, PDA, cellular device). To conserve power, the wireless components of the input device are powered down during periods of non-transmission. The wireless input device detects intermediate user input and corresponding data according to a detection rate during periods of non-transmission. The intermediate data is then transmitted to the receiving device during a transmission period along with a current data detected at the time of transmission. The wireless device may further discard any intermediate data which does not reflect a significant change. Additionally, the system and method may include a detection rate that adapts to degrees of user activity detected by the wireless input device.

US Classification:

Abstract:

This document describes tools that enable secure communication between devices that are within a user's common control. These commonly controlled devices may follow a protocol, for example, where each commits to its own public key and receives a commitment of the other's public key, publishes its own public key and receives the other's public key, and authenticates the other's public key based on the received commitment of the other's public key. If authentic, each device computes an identifier based on the other's public key and its own private key associated with its own public key. A user may interact with the devices to confirm that the identifiers are the same. If they are the same, the devices may communicate securely.
