Strong Privacy for RFID Systems from Plaintext-Aware Encryption

Abstract

Modeling privacy for RFID protocols went through different milestones. One pretty complete model was proposed by Vaudenay at ASIACRYPT 2007. It provides a hierarchy of privacy levels, depending on whether corruption is addressed by the protocol and on whether the return channel from the reader is available. The strongest notion of privacy was proven to be impossible to achieve, but the counterexample which was given was not convincing. Somehow, it showed that the requirements for strong privacy were unnecessarily too high. Several amendments were considered until a slight change in the definition which was proposed at CANS 2012. There, the simulator (blinder) was given access to the adversary's random tape, making him able to read his mind. Thanks to plaintext-aware encryption, we can now prove that strong privacy is possible.

Privacy law

Privacy law is the body of law that deals with the regulating, storing, and using of personally identifiable information, personal healthcare information, and financial information of individuals, which can be collected by governments, public or private organisations, or other individuals. It also applies in the commercial sector to things like trade secrets and the liability that directors, officers, and employees have when handing sensitive information.

Privacy

Privacy (UK, US) is the ability of an individual or group to seclude themselves or information about themselves, and thereby express themselves selectively. The domain of privacy partially overlaps with security, which can include the concepts of appropriate use and protection of information. Privacy may also take the form of bodily integrity. There have been many different conceptions of privacy throughout history. Most cultures recognize the right of an individual to withhold aspects of their personal lives from public record.

Right to privacy

The right to privacy is an element of various legal traditions that intends to restrain governmental and private actions that threaten the privacy of individuals. Over 150 national constitutions mention the right to privacy. On 10 December 1948, the United Nations General Assembly adopted the Universal Declaration of Human Rights (UDHR), originally written to guarantee individual rights of everyone everywhere; while right to privacy does not appear in the document, many interpret this through Article 12, which states: "No one shall be subjected to arbitrary interference with his privacy, family, home or correspondence, nor to attacks upon his honour and reputation.
