Public-key cryptography for RFID-tags
2007Co-Authors: Lejla Batina, T. Kerins, Nele Mentens, Pim Tuyls, Jorge Guajardo, Ingrid VerbauwhedeAbstract:RFID-tags are a new generation of bar-codes with added functionality. An emerging application is the use of RFID-tags for anti-Counterfeiting by embedding them into a product. Public-key cryptography (PKC) offers an attractive solution to the Counterfeiting problem but whether a publickey cryptosystem can be implemented on an RFID tag or not remains unclear. In this paper, we investigate which PKC-based identification protocols are useful for these anti-Counterfeiting applications. We also discuss the feasibility of identification protocols based on elliptic curve cryptography (ECC) and show that it is feasible on RFID tags. Finally, we compare different implementation options and explore the cost that side-channel attack countermeasures would have on such implementations

rfid tags for anti Counterfeiting
2006Co-Authors: Pim Tuyls, Lejla BatinaAbstract:RFID-tags are becoming very popular tools for identification of products. As they have a small microchip on board, they offer functionality that can be used for security purposes. This chip functionality makes it possible to verify the authenticity of a product and hence to detect and prevent Counterfeiting. In order to be successful for these security purposes too, RFID-tags have to be resistant against many attacks, in particular against cloning of the tag. In this paper, we investigate how an RFID-tag can be made unclonable by linking it inseparably to a Physical Unclonable Function (PUF). We present the security protocols that are needed for the detection of the authenticity of a product when it is equipped with such a system. We focus on off-line authentication because it is very attractive from a practical point of view. We show that a PUF based solution for RFID-tags is feasible in the off-line case.

plant derived fluorescent silicon nanoparticles featuring excitation wavelength dependent fluorescence spectra for anti Counterfeiting applications
2016Co-Authors: Yiling Zhong, Binbin Chu, Bin Sun, Bin SongAbstract:By using gramineae plants as natural and accessible reaction precursors, we herein introduce a green synthetic strategy, which is efficacious for the facile production of crystalline, excitation-wavelength-dependent fluorescent and small-sized silicon nanoparticles (SiNPs). We further explore the prepared SiNPs as a novel kind of fluorescent label for anti-Counterfeiting applications.

fluorescent and magnetic anti Counterfeiting realized by biocompatible multifunctional silicon nanoshuttle based security ink
2018Co-Authors: I Song, Yiling Zhong, Houyu Wang, Inbi ChuAbstract:Herein, we present the first example of a silicon nanoshuttle-based security ink simultaneously featuring attractive optical and magnetic properties, suitable for fluorescent and magnetic anti-Counterfeiting and encryption. Significantly, the information can be dual-encrypted through multi-color fluorescence and longitudinal (T1)/transverse (T2) relaxation contrast by using the silicon nanoshuttle-based security ink. We further demonstrate the feasibility of this high-performance ink for practical application in banknote anti-Counterfeiting.

highly luminescent dual mode polymeric nanofiber based flexible mat for white security paper and encrypted nanotaggant applications
2018Co-Authors: Pawan Kumar, Amit Kumar Gangwar, Ashish Gupta, Garima Kedawat, Bhanu Pratap Singh, Nidhi Singh, Avanish Kumar SrivastavaAbstract:Increasing Counterfeiting of important data, currency, stamp papers, branded products etc., has become a major security threat which could lead to serious damage to the global economy. Consequences of such damage are compelling for researchers to develop new high-end security features to address full-proof solutions. Herein, we report a dual mode flexible highly luminescent white security paper and nanotaggants composed of nanophosphors incorporated in polymer matrix to form a nanofiber-based mat for anti-Counterfeiting applications. The dual mode nanofibers are fabricated by electrospinning technique by admixing the composite of NaYF4 :Eu3+ @NaYF4 :Yb3+ , Er3+ nanophosphors in the polyvinyl alcohol solution. This flexible polymer mat derived from nanofibers appears white in daylight, while emitting strong red (NaYF4 :Eu3+ ) and green (NaYF4 :Yb3+ , Er3+ ) colors at excitation wavelengths of 254 nm and 980 nm, respectively. These luminescent nanofibers can also be encrypted as a new class of nanotaggants to protect confidential documents. These obtained results suggest that highly luminescent dual mode polymeric nanofiber-based flexible white security paper and nanotaggants could offer next-generation high-end unique security features against Counterfeiting.

future prospects of luminescent nanomaterial based security inks from synthesis to anti Counterfeiting applications
2016Co-Authors: Pawan Kumar, Satbir Singh, Bipin Kumar GuptaAbstract:Counterfeiting of valuable documents, currency and branded products is a challenging problem that has serious economic, security and health ramifications for governments, businesses and consumers all over the world. It is estimated that Counterfeiting represents a multi-billion dollar underground economy with counterfeit products being produced on a large scale every year. Counterfeiting is an increasingly high-tech crime and calls for high-tech solutions to prevent and deter the acts of Counterfeiting. The present review briefly outlines and addresses the key challenges in this area, including the above mentioned concerns for anti-Counterfeiting applications. This article describes a unique combination of all possible kinds of security ink formulations based on lanthanide doped luminescent nanomaterials, quantum dots (semiconductor and carbon based), metal organic frameworks as well as plasmonic nanomaterials for their possible use in anti-Counterfeiting applications. Moreover, in this review, we have briefly discussed and described the historical background of luminescent nanomaterials, basic concepts and detailed synthesis methods along with their characterization. Furthermore, we have also discussed the methods adopted for the fabrication and design of luminescent security inks, various security printing techniques and their anti-Counterfeiting applications.
