Thwarting unlawful redistribution of information sold electronically is a major problem of information-based electronic commerce. Anonymous ngerprinting has appeared as a technique for copyright protection which is compatible with buyer anonymity in electronic transactions. However, the complexity of known algorithms for anonymous ngerprinting is too high for practical implementation on standar...

In this paper, adapting a novel dual authentication method based on smart cards in public networks is proposed. This method uses the ElGamal public key cryptosystem and extend Chaum–van Antwerpen’s scheme to authenticate a signature between the signer and verifier using a dual protocol with a smart card that has tamper-resistant features. We propose the method to change the verification and dis...

Integrated fares and electronic ticketing are frequently advocated by transport planning authorities to promote public transport use. But how effective and necessary are integrated fares and electronic ticketing for urban NZ. This paper reviews the state of play in New Zealand in 2009 and draws some lessons from overseas. Fare differentiation, the flip side of integrated fares, also has merit s...

Attribute based signature (ABS) is a novel cryptographic primitive, which enables a party can sign messages for any predicate satisfy by their attributes. However, heavy computational cost is required during the verification procedure in most existing ABS schemes, which may needs many pairing operations. Pairing are costly operation when compared to exponentiation in the base group. As a result...

ÐThis paper examines how monitoring power consumption signals might breach smart-card security. Both simple power analysis and differential power analysis attacks are investigated. The theory behind these attacks is reviewed. Then, we concentrate on showing how power analysis theory can be applied to attack an actual smart card. We examine the noise characteristics of the power signals and deve...

Contactless smart cards are used in access control and payment systems. This paper illustrates an attack which effectively allows an attacker to ‘borrow’ the victim’s card for a short period without requiring physical access to the victim’s card. As a result the legitimate owner will remain unaware of the attack. We show that our hardware successfully executed a relay attack against an ISO 1444...

The executions of operating system services based on smart cards allow one to personalize some functionalities of the operating system by using the secret information stored in a smart card and the basic computations that a smart card can perform. However, current solutions for integrating smart card features in operating system services require at least a partial execution of the operating sys...

A myriad of applications such as radio frequency identification (RFID) and smart card networks are emerging in which nodes are designed for extremely low-cost, large scale applications such that the replacement of batteries is not feasible. Energy conservation therefore becomes a major constraint. Classical access protocols are either not energy conserving or lead to unacceptable delays. In a p...

A remote user authentication system has become an important part of security, along with confidentiality and integrity, for systems such as the Internet that offer remote access over untrustworthy networks. In 2006, Liaw et al. proposed an efficient and complete remote user authentication scheme using smart cards that includes a session key being agreed and an updated password phase. However, t...

Slovenia initiated a nation-wide project to introduce smart cards in the health sector in 1995 and its full-scale deployment started in September 2000. Although the basic aim of the project was to support insurance related procedures, the system was designed in a flexible and open manner to present an infrastructure for the whole health sector. The functionality of the current system is describ...
