Mar 03, 2013The use of smart-card ICs has become more widespread, expanding from historical banking and telecommunication applications to electronic passports, electronic IDs, anti-counterfeiting devices, smart-grid applications and more. The security requirements for most of these applications are crucial and evolving, and more sophisticated attacks are being developed daily. NXP Semiconductors summarizes the security challenges of using smart-card ICs, and describes how a technology known as Physical Unclonable Functions (PUF) delivers comprehensive protection in current applications. PUF technology provides a secure method for storing a key and protecting against attacks. (8 pages)
