3.6 Coopetitive Architecture SPR9. Feature Interaction Management: The SPs require that any changes to the smart card platform that can aect their application's execution should be avoided. In the best-case scenario, the smart card platform follows the SP's delegated process that removes the interdependencies between applications in such situations. However, if this does not solve the problem, then the card should simply block the application or possibly delete it (with the card owner's consent). SPR10. Protection from Malicious Users: The SPs would like to have their applications protected by the underlying smart card platform. Therefore, even if the application were issued to the malicious user, he would not be able to obtain any sensitive information about the application. 3.6 Coopetitive Architecture A UCTD can be a single-user, and/or a multi-user device, depending upon its deployment architecture. In a multi-user architecture, a device (e.g. a computer or tablet) might be used by multiple users. Furthermore, a UCTD might be part of a corporate network, as in the case of a mobile phone issued to employees by an organisation. The organisation (referred as an administrative authority) would like to retain the control of the UCTD issued as part of the mobile phone, while giving freedom to the user to have/manage the UCTD independently of the organisation. It is necessary to consider these deployment scenarios in order to achieve true scalability that will enable small to medium-sized organisations like leisure facilities, local libraries, schools, surgeries and colleges, as well as large-scale organisations like banks, MNOs and transport operators, to provide their services through a UCTD to a user without any restrictions from a centralised authority (e.g. card issuer). To accommodate the role of an administrative authority on a UCTD, we extend the UCOM architecture and propose the Coopetitive Architecture for Smart Cards (CASC). In the CASC a cardholder retains the application choice but under the provision of an administrative authority (e.g. TSM). Nevertheless, the baseline architecture of the UCTD is based the UCOM, as the CASC is an extension of the UCOM architecture that provides centralised ownership of the device while preserving the user's freedom of choice. The CASC combines the TSM architecture with the openness, scalability, and exibility of the UCOM architecture. In this architecture, users get their choice of selecting which application they want on their smart cards, and administrative authorities (or the TSM, the administrator of the corporate network) have a permanent presence on the cards along with possibly being part of the revenue loop. The CASC requires all the necessary modications to the existing smart card architecture (i.e. deployed in the ICOM) to achieve its goals. So while we focus on the UCOM in this thesis, we are implicitly also catering to the 76
Service Provider 3.6 Coopetitive Architecture Standardisation Bodies and Industrial Forums Common Criteria Platform Manager (PM) Cardholder Card Manufacture PM Card Terminal Manufacturer Figure 3.7: Ecosystem of the Coopetitive Architecture for Smart Cards (CASC) requirements of the CASC. The ecosystem of the CASC is illustrated in gure 3.7, and at its centre there are three main entities: the administrative authority (the card issuer, TSM, and corporate authority etc.), cardholder, and the smart card. The administrative authority issues the smart cards to its customers. The cardholder would have the choice to install or delete any application they would require. The management of the smart card application installation, deletion, and application/card lifecycle management is handled by the Platform Manager (PM) (discussed in section 4.2). The PM facilitates both the administrative authority and the cardholder to perform their sanctioned tasks. As an example, consider a scenario in which a user enrols into the multi-application smart card service architecture through a Mobile Network Operator (MNO). In this scenario, the MNO plays the role of an administrative authority. As the customer of the MNO, the user can receive an NFC-enabled mobile phone (possibly under a xed period contract) and UCTDs. In certain cases, MNOs subsidise the mobile phone in return for a xed period contract with their customers. The phone is under MNO lock and it can only be used on the issuing MNO's network. At the end of the contract, the customer can request the MNO to unlock the mobile phone. The acquired secure element(s) would have the MNO's application installed by default. In addition, if the user is a customer of any other organisations that are associated partners of the MNO in the TSM scheme, then she may get their applications pre-installed on the secure element. This secure element would enable the user to request installation or deletion of any application she chooses, except 77
