This paper provides detailed information on iCLASSTMreader and key security. It explains the security problems found without revealing the extracted secret keys (DES authentication Key and the 3DES data encryption key for iCLASSTMStandard Security cards). The chosen approach of not releasing the encryption and authentication keys gives iCLASS vendors and customers an important headstart to upda...

Fingerprint classification reduces the searching time of an automated fingerprint identification system. Since fingerprints have properties of intra-class diversities and inter-class similarities, the ambiguous example causes a difficult problem in the fingerprint classification. In order to address the problem, we have analyzed fingerprints’ subclasses with multiple decision templates. It clus...

This paper presents the design, implementation, and evaluation of the RFID Guardian, the first-ever unified platform for RFID security and privacy administration. The RFID Guardian resembles an “RFID firewall”, enabling individuals to monitor and control access to their RFID tags by combining a standard-issue RFID reader with unique RFID tag emulation capabilities. Our system provides a platfor...

NIST’s Lightweight Cryptography Project ties selected crypto­ graphic algorithms to a profile, which captures the physical, performance and security characteristics of the target devices that run these algorithms. This contribution investigates the role of energy in the profile. For many of the important application domains of Lightweight Cryptography, the opera­ tion is intermittent, rather th...
