Location-aware sign-on and key exchange using attribute-based encryption and Bluetooth beacons
This addresses the need for seamless and secure authentication in mobile environments, but it appears incremental as it combines existing technologies like Bluetooth beacons and Attribute-Based Encryption.
The paper tackles the problem of secure and convenient mobile authentication by proposing a location-aware sign-on scheme that uses Bluetooth beacons and Attribute-Based Encryption, enabling users to perform simplified logins as they move between locations.
This work presents a mobile sign-on scheme, which utilizes Bluetooth Low Energy beacons for location awareness and Attribute-Based Encryption for expressive, broadcast-style key exchange. Bluetooth Low Energy beacons broadcast encrypted messages with encoded access policies. Within range of the beacons, a user with appropriate attributes is able to decrypt the broadcast message and obtain parameters that allow the user to perform a short or simplified login. The effect is a "traveling" sign-on that accompanies the user throughout different locations.
