Abstract
A start value is x bits in size and is used to provide an initial value to an n-bit security count value. A wireless communications device establishes channels with a compatible device, and releases channels established with the compatible device. For every channel established by the wireless communications device, a corresponding terminal value is obtained. A terminal value for a channel is the highest value reached by the x most significant bits (MSB ) of an n-bit security count value associated with the channel. The security count value is used to encipher data transmitted along the channel. A final value that is obtained that is the greatest value of all the terminal values. Finally, a start value is stored in the memory of the wireless device that is at least as large as the final value.
