CASTWED: continuous authentication combining smart terminal with wearable devices in mobile satellite communication system

Wearable devices, such as smart watches or smart bracelets, have been growing rapidly worldwide. These devices with various sensors have the ability to perceive the circumstance and user's biometric features, which can be used to continuously authenticate a user's identity. However, these features have not been studied to identify a specific user in mobile satellite communication system yet, due to its low data transfer rate and unacceptable delay. To solve this problem, continuous authentication combing smart terminal with wearable devices (CASTWED) was studied in mobile satellite communication system, the security of CASTWED was also theoretically analyzed. Simulation experiments show that the CASTWED scheme can provide simultaneous online authentication service for 100000 users via 60 Mbit/s Ku wave band.
