Encryption-based Security in Wearable Devices.

Wearable devices have become common accessories used in tracking fitness data or augmenting daily smartphone usage. However, not all manufacturers of inexpensive wearable devices have done sufficient work to protect the privacy of their users. Some devices have shown vulnerabilities that allow attackers to obtain data stored on a locked device. In this paper, we examine using ASCON, a set of lightweight cryptographic algorithms, to enhance security of wearable devices by encrypting locally stored data.
