AONT Encryption Based Application Data Management in Mobile RFID Environment

摘要

Mobile RFID (radio frequency identification) is a new application that allows the use of a mobile phone as a wireless RFID reader and provides new services to users by integrating RFID and the ubiquitous sensor network infrastructure with mobile communication and wireless internet services. Ensuring the security of mobile RFID's large-capacity database system by depending only on existing encryption schemes is unrealistic. In this regard, data sharing for security management has drawn attention as an extremely secure scheme. However, applying the existing secret sharing scheme to this method makes the size of the share equal to that of the original data, making it unsuitable for application to a large-scale database. To address this problem, this paper proposes secret sharing algorithms that enable efficient data security management through the use of the characteristics of the all-or-nothing transform (AONT) encryption in RFID middleware.
