Description: Cryptanalysis of INCrypt32 in HID s iCLASS Systems
ChangKyun Kim, Eun-Gu Jung, Dong Hoon Lee, Chang-Ho Jung, and Daewan Han
Category / Keywords: secret-key cryptography / INCrypt32, HID s iCLASS, RFID, reverse engineering, chosen message attack.-Abstract: The cryptographic algorithm called INCrypt32 is a MAC algorithm to authenticate participants, RFID cards and readers, in HID Global s iCLASS systems. HID s iCLASS cards are widely used contactless smart cards for physical access control. Although INCrypt32 is a heart of the security of HID s iCLASS systems, its security has not been evaluated yet since the specication has not been open to public. In this paper, we reveal the specication of INCrypt32 by reverse engineering an iCLASS card and investigate the security of INCrypt32. As a result, we show that the secret key of size 64 bits can be recovered using only $2^{18}$ MAC queries if the attacker can request MAC for chosen messages of arbitrary length. If the length of messages is limited to predetermined values by the authentication protocol, the required number of MAC queries grows to $2^{42}$ to recover the secret key.

Description: 奥地利微电子的AS1910 RFID芯片，是较其它同功能芯片更有突出特征的芯片。支持1W功率，天线自动调谐。但该公司的Demo程序做的过于复杂，调试过程容易死机。本文给出该公司Demo板调试的主要协议指令，方便大家直接用其它程序调试或者自动封装成接口库不修改固件情况下直接开发应用。-Austria microelectronics AS1910RFID chip, is other than the same function chip more prominent feature of the chip. Support1W power, antenna automatic tuning. But the company Demo procedures do too complex, the debugging process easy to halt. This paper gives the company Demo debug board the main protocol instruction, facilitate direct other program or automatic package interface library does not modify the firmware directly under the development and application of.

Description: 提出两种基于盲源分离方法的标签防碰撞算法，解决标签密集的多天线RFID 系统中的标签碰撞问题。在一个确定的
时隙内， 当发射反向反馈信号的标签数目不超过阅读器天线的数目时， 这些标签可以通过盲源分离算法被阅读器成功识
别；信号，直到所有标签被成功识别出来。仿真结果表明，新算法能使得RFID 系统获得更加高效的吞吐率，能比基于ALOHA
的标签防碰撞算法具有更小的时耗，尤其是当标签数目较大时更加显著。-two tag anti－collision algorithms based on blind source separation (BSS) method are presented to solve the
tag collision problem for dense multi －antennas RFID system in this paper．When the number of tags that transmitting
backscattering signal in a confirmed slot is not exceed the number of antennas of the reader,these tags can be identified
by using blind source separation algorithm．Otherwise,these tags cannot be identified,and they randomly one of other
slots in the same frame and transmit the return signal to the reader until all tags have been identified successfully

Description: 这是一个射频识别防碰撞的程序，其中采用的是二进制算法，结果有对比图，效率明显提高-Abstract The deployments of RFID system are seriously affected by collision caused by multiple tags responding simultaneously. To facilitate the resolution of collisions caused by densely distributed memoryless passive tags in successive cycles, based on the binary query tree protocol, this paper proposes a new Successive Scheme. In this scheme, the binary query tree constructed by the protocol will be reused.

Description: — In this current world the passport and other identification docuentms may be improved by this enhancing technology. This can be brought in practical by pursuing electronic machine reliable approaches with biometric information International Civil Aviation Organization(ICAO) has adopted a standard were by passports and other documents can be stored biometric identifier. However, the selection of technology is questionable till 2006 due to the security and privacy concern. This paper tells the advancement in the electronic approaches and developments towards electrical storage and transmission. RFID i.e. Radio Frequency Identifier Devices for electronic passports and other identify documents are discussed.

Description: In this paper, we review candidate antenna technologies for isolating RFID tag antennas
(HF, UHF, and microwave) from the objects on
which they are attached. Our primary focus is the
incorporation of magnetic materials into RFID tag
substrates, which hold the greatest potential performance enhancements, but is fraught with several
physical limitations. We conclude by reviewing new
breakthroughs in superparamagnetic materials that
could revolutionize future RFID tag antenna isolators.
