Electronic money (e-money or e-Cash) is the digital representation of physical banknotes augmented by added use cases of online and remote payments. This paper presents a novel, anonymous e-money transaction protocol, built based on physical unclonable functions (PUFs), titled PUF-Cash. PUF-Cash preserves user anonymity while enabling both offline and online transaction capability. The PUF’s privacy-preserving property is leveraged to create blinded tokens for transaction anonymity while its hardware-based challenge–response pair authentication scheme provides a secure solution that is impervious to typical protocol attacks. The scheme is inspired from Chaum’s Digicash work in the 1980s and subsequent improvements. Unlike Chaum’s scheme, which relies on Rivest, Shamir and Adlemans’s (RSA’s) multiplicative homomorphic property to provide anonymity, the anonymity scheme proposed in this paper leverages the random and unique statistical properties of synthesized integrated circuits. PUF-Cash is implemented and demonstrated using a set of Xilinx Zynq Field Programmable Gate Arrays (FPGAs). Experimental results suggest that the hardware footprint of the solution is small, and the transaction rate is suitable for large-scale applications. An in-depth security analysis suggests that the solution possesses excellent statistical qualities in the generated authentication and encryption keys, and it is robust against a variety of attack vectors including model-building, impersonation, and side-channel variants.

“…The features of the final version of the segmented images are extracted and it is compared with the already stored feature details of the reference data, when the result of comparison is greater than a threshold, a decision is made on whether the given note is fake or real. Sakalauskas [2] has proposed an effective realization for an e-wallet system, the proposed system uses Elgamal Asymmetric Encryption Scheme for digital signatures generation and verification. SHA 256 algorithm is used for defining Payment parameters.…”

“…In the system [2], the author demonstrates the security using two parts of electronic circuitry; one part is a small and elongated magnet which is placed in the wallet. The other part is the electronic circuitry and audio producing device in which the circuit activating switch is held open as long as the wallet with its magnet is in proximity to the second part.…”

 Abstract: The main objective is to create a security system for wallet based on RFID technology and also keep an account of how much money is coming inside and going out of the wallet which is done using tcs3200 colour sensor by which we can have an account of the amount of money spent and update the same on the mobile app. So, this project basically alerts the person if the wallet is missing from his/her pocket and also shares the location of the same and also gives the information of how much he/she has spent. The major components used in this paper include Raspberry PI, RFID Reader, RFID Tag, GPS Module, and TCS3200 Colour Sensor. Whenever the RFID card is placed near to the reader, the RFID reader obtains the UID (unique key) information about the card. The location of the wallet is obtained using the GPS Module. This detail is notified to user when the wallet is not connected. The status obtained by the RFID reader and the GPS module is collected by Raspberry PI. Using the PI's WIFI, the details are posted onto the cloud. All the details posted onto the cloud are accessed via the APP and also through a website portal in case of any emergency

“…Since the observer in this system is the chip implemented in user's device, it is necessary to supply the chip with proper cryptographic functions. In [21], we suggested using physical unclonable functions (PUFs, [14]) as a better way of ensuring the suitability of cryptographic functions and the security of e-money system. It was also mentioned in [21] that PUFs allow user to extract a unique unclonable code (UUC) for the chip and to create a unique cryptographic key.…”

A simple mobile e-cash system with observers satisfying e-cash divisibility, partial anonymity, off-line payment, transferability and double-spending prevention requirements is presented. The proposed e-cash system is based on two well-known cryptographic primitives, namely ElGamal signature along with Schnorr identification protocols. Therefore, it can be considered simple in the sense of implementation and security considerations. The traditional and elliptic curve realizations of e-money system are presented. The system employs observers, i.e. cryptographic bank chips implemented in customer's payment device (e.g. smart phone) in order to avoid the increase in the size of transferred e-cash data, which is a major flaw of most divisible, anonymous, off-line and transferable e-cash systems. The security of the proposed e-money system is based on discrete logarithm problems in cyclic and elliptic curve groups. The system's security against chosen message attack is provided.
