https://en.wikipedia.org/wiki/A5/1
A5/1 is a stream cipher used to provide over-the-air communication privacy in the GSM cellular telephone standard. It is one of seven algorithms which were specified for GSM use. It was initially kept secret, but became public knowledge through leaks and reverse engineering.A number of serious weaknesses in the cipher have been identified.
