A Location Based Encryption Technique and Some of Its Applications

Abstract

Location based encryption enhances security by integrating position and time into encryption and decryption processes. We find that from a security perspective, it is not enough to simply enable or disable decryption based on location and time; these aspects must be integrated into the key construction process. Furthermore, keys or files in transit should not reveal anything regarding their locations/times of applicability. After reviewing the objectives of location-based encryption, this paper introduces a specific approach called geo-encryption.
