We propose two RFID localization approaches to ascertain the estimated location of a target that has a passive tag affixed. The antennas of the RFID readers are installed on the ceiling of an indoor environment as this setup will facilitate the daily routine operations of warehouses, retail stores and libraries. The reader leveled nearest-neighbor and multilateration schemes take advantage of detectable...
We implement and test the performance of an RFID hash algorithm recently proposed by Adi Shamir using a C++ simulation. The algorithm, called SQUASH (short for “SQUarehASH”), allows for an RFID tag design that is simple enough to be implemented on low-cost RFID tags. Shamir has proved mathematically that his SQUASH algorithm is at least as secure as the Rabin cryptosystem, which has been extensively...
This study extends the vulnerability analysis of a RFID authentication protocol and offers solutions to security weaknesses through enhanced measures. Vajda and Buttyan (VB) proposed a set of five lightweight RFID authentication protocols. Defend, Fu, and Juels (DFJ) did cryptanalysis on two of them - XOR and SUBSET. DFJ proposed repeated keys and nibble attacks on the XOR protocol. In this paper,...
