Title: (EN) SYSTEM AND METHOD FOR SECURING A COMMUNICATION CHANNEL
Abstract: front page image
(EN)

A system and method for securing a communication channel may include obtaining a first value by first and second devices. A second value may be randomly selected by the first device and may be provided to the second device. The first and second devices may independently from one another apply a function to the first and second values and may use a result of the function to secure and authenticate a communication channel between the first and second devices.
