“…Moreover, these studies have considered the following methods to provide authentication in electronic Payment systems (including Mobile commerce (M-commerce): username/password, symmetric, asymmetric and elliptic curve cryptography, smart card, 2d bar code, and biometric methods. There are many authentication mechanisms and protocols based on these methods [3,4,11,12,15,25,26,33,35,40,47] but some of them do not offer enough security for M-commerce whilst symmetric and asymmetric signatures have been widely used for authentication purposes.…”

In the last few years, many value-added applications (such as Payment services) in Vehicular Ad hoc NETworks (VANETs) have emerged. Although these applications offer great business opportunities they also introduce new concerns regarding security and privacy. Moreover, the wide range of scenarios (with or without connectivity restrictions) arising from vehicle-to-vehicle and vehicle-to-roadside communications have opened up new security challenges which must be considered by Payment system designers to achieve the same security capabilities independent of the scenario where Payment occurs. We designed and implemented a lightweight (using symmetric-key operations which requires low computational power) secure Payment protocol for those scenarios in VANETs and other mobile environments where the Merchant cannot communicate directly with the Acquirer (the Merchant's financial institution) to process the Payment Request. We also present practical performance results that can be achieved with the proposed Payment protocol.

“…Given our trust model this is easy to require of the set of clients and servers. For WayStations, we depend on the presence of a public key infrastructure [4,6] or alternate key management system [10]. Note that merely knowing the public key of a WayStation does not automatically convey a trust relationship; it merely establishes the identity of that WayStation.…”

Mobile nodes rely on external services to provide safety, sharing, and additional resources. Unfortunately, as mobile nodes move through the networking infrastructure, the costs of accessing servers change. Fluid replication allows mobile clients to create replicas where and when they are needed. Unfortunately, one must trust the nodes holding these replicas, and establishing trust in autonomously administered nodes is a difficult task. Instead, we argue that trust should be deferred. In this position paper, we present the design of Stonewall, a system that defers trust decisions through the use of two mechanisms: packages and receipts. The former ensure confidentiality and detect breaches of integrity; the latter detect breaches of non-repudiation.

“…Recently, there has been substantial interest in public key technologies [2,3,4] being used to support secure electronic communications. In order to use public key cryptography, it is necessary to make an entity's public key available to others in such a way that its authenticity (i.e., its status as the true public key of that entity) and validity are verifiable.…”

Abstract.A Certificate Management System (CMS) is used to generate, distribute, store and verify certificates. It supports secure electronic communication through its functions. This paper presents a state-based model for certificate management systems. The axiomatization of CMS structures and the security policy followed by CMSs is discussed. The main functions of a CMS, including certificate issuing, certificate revocation and certificate rekeying, are formally described through transitions that change states of the CMS. A major CMS client function, certificate verification, is also formally discussed. With this model, an approach to the formal specification of the structure and behavior of a CMS is provided. The approach is very general, and would be useful in guiding the developer and the evaluator of a CMS with the design, analysis and implementation of the system.
