GeoFPE: Format Preserving Encryption of Geospatial Data for the Internet of Things

The rise Internet of Things (IoT) over the last years has allowed more and more devices to be connected and interact between themselves. Many of these devices, such as vehicles have to deal with geographic information, often considered as sensitive by many car manufacturers, like the BMW Group. For securely storing this geographic information, usually block ciphers are used. Unfortunately, they imply the disadvantage of breaking existing formats and compatibilities. To address this problem, we propose a new algorithm for storing geographic spatial information in IoT devices and the Cloud securely while preserving the existing format.
