Trapping Unauthorized Signals in Jammer

This paper presents a mechanism, called Authorized Jammer, which provide jamming capability that can trapped unauthorized wireless signals and at the same time access authorized communication. The jammer jams the wireless signals continuously by using secret keys, so that the jamming signals identify the signals come from unauthorized devices, and can access the signals by authorized devices with the secret keys. To achieve this jammer by developing new design circuit for trapping the signals. This paper assume authorized devices as mobile phones signals and other than that assume unauthorized devices.
