| dc.description.abstract | [Abstract] Amazon Alexa processes voice commands as input to help users perform tasks. For
protecting this commands, Amazon Alexa implements some security measures. These security
measures, such as voice recognition and user’s PIN, do not have the ability to mitigate replay
attacks. In order to mitigate replay attacks, in this paper, we propose an authentication method
based on Geofencing, consisting of (1) an Android application and (2) an Alexa Skill. By using
the Android application, the user is able to configure a geofence near the Amazon Echo smart
speaker. The developed Alexa Skill only accepts requests when the user is within the established
geofence. This method mitigates replay attacks: an attacker could only try to use a replay attack
when the legitimate user is close to the speaker, making it unfeasible | es_ES |
