Towards More Secure RFID Chips
Researchers at MIT and a related spinoff company have been working on a new system to enhance the encryption of data on RFID chips. RFID has long been a concern of security professionals and has been identified by the Privacy Commissioner of Canada as a major privacy concern.
The researchers have been working on algorithms that are derived from faults that exist in every chip and that differ for every chip. Thus, since the algorithms are unique to each chip, they can be used for authentication purposes.
Encryption is the single most important means for safeguarding data, particularly data in mobile units like RFID chips. Click here for an article on this research.
