With strict limits on area and power consumption, it's quite significant to design a novel RFID-suitable security scheme. In this paper, a lattice based public-key encryption scheme, the LWE cryptosystem is studied and the applicability for RFID system is assessed. The advantages and defects for the scheme to be implemented on hardware is analyzed, and(More)
This paper presents an analog front-end circuit for semi-passive HF RFID tag compatible to ISO/IEC 14443 Type A. System architecture is constructed. The proposed AFE has realized much longer recognition distance than passive tags and can work normally when the magnetic field is 0.3 A/m. It was fabricated with HHNEC 0.13 μm 1P4M CMOS technology with(More)
This paper describes the design and implementation of a performance testing tool for E-commerce systems. This tool can be used to assess the system performance based on TPC-W benchmark. The main features and designing considerations of the tool as well as testing procedures are discussed. The test results of applying this tool to two real systems have been(More)
