Abstract
This disclosure describes techniques for performing enhanced authentication of a device based on physical and logical proximity of the device to one or more other authenticated devices. An example method includes performing, at a first time, a first authentication of a first device or a first user of the first device and determining that the first device is connected to at least one second device in a communication session. The at least one second device or at least one second user of the at least one second device are authenticated. The example method further includes determining a reauthentication interval based on the first device being connected to the at least one second device in the communication session and initiating, at a second time that is after the first time by the reauthentication interval, a second authentication of the first device or the first user of the first device.
