Abstract: Some embodiments provide a method for establishing a secured session with backward security between a first device and a second device. In some embodiments, the method establishes a communication session between the first and second devices using shared keys stored at the first and second devices. The method exchanges encrypted data between the first and second devices as a part of the communication session. The method, upon completion of the communication session, modifies the shared key at the first device in a predictable way. The shared key is modified at the second device in the same predictable way. The method then stores the modified shared key at the first device. The modified shared key cannot be used to decrypt any portion of the encrypted data of the current and previous communication sessions.

Abstract: This document describes, inter alia, techniques for use at a wireless device for establishing communications with other devices, and for displaying related information in a graphical user interface. The wireless device may discover, pair with, and/or connect to other wireless devices, and may display a list of information regarding the other wireless devices in a graphical user interface. The wireless device may order the list based on factors such as: the connectivity status of the other devices (e.g., whether the other devices are connected, paired, or discovered); the types of the other wireless devices (e.g., whether the devices are human interface devices (HIDs), audio devices, phones, imaging devices, computers, or other types of devices); whether device names for the other wireless devices are known/unknown; and/or other factors. The features described herein may be implemented using Bluetooth wireless technology, and/or any other wireless technology.
