Citizen Electronic Identities using TPM 2.0

Electronic Identification (eID) is becoming commonplace in several European countries. eID is typically used to authenticate to government e-services, but is also used for other services, such as public transit, e-banking, and physical security access control. Typical eID tokens take the form of physical smart cards, but successes in merging eID into phone operator SIM cards show that eID tokens integrated into a personal device can offer better usability compared to standalone tokens. At the same time, trusted hardware that enables secure storage and isolated processing of sensitive data have become commonplace both on PC platforms as well as mobile devices. Some time ago, the Trusted Computing Group (TCG) released the version 2.0 of the Trusted Platform Module (TPM) specification. We propose an eID architecture based on the new, rich authorization model introduced in the TCGs TPM 2.0. The goal of the design is to improve the overall security and usability compared to traditional smart card-based solutions. We also provide, to the best our knowledge, the first accessible description of the TPM 2.0 authorization model.Comment: This work is based on an earlier work: Citizen Electronic Identities using TPM 2.0, to appear in the Proceedings of the 4th international workshop on Trustworthy embedded devices, TrustED'14, November 3, 2014, Scottsdale, Arizona, USA, http://dx.doi.org/10.1145/2666141.266614

Formal security analysis of registration protocols for interactive systems: a methodology and a case of study

In this work we present and formally analyze CHAT-SRP (CHAos based Tickets-Secure Registration Protocol), a protocol to provide interactive and collaborative platforms with a cryptographically robust solution to classical security issues. Namely, we focus on the secrecy and authenticity properties while keeping a high usability. In this sense, users are forced to blindly trust the system administrators and developers. Moreover, as far as we know, the use of formal methodologies for the verification of security properties of communication protocols isn't yet a common practice. We propose here a methodology to fill this gap, i.e., to analyse both the security of the proposed protocol and the pertinence of the underlying premises. In this concern, we propose the definition and formal evaluation of a protocol for the distribution of digital identities. Once distributed, these identities can be used to verify integrity and source of information. We base our security analysis on tools for automatic verification of security protocols widely accepted by the scientific community, and on the principles they are based upon. In addition, it is assumed perfect cryptographic primitives in order to focus the analysis on the exchange of protocol messages. The main property of our protocol is the incorporation of tickets, created using digests of chaos based nonces (numbers used only once) and users' personal data. Combined with a multichannel authentication scheme with some previous knowledge, these tickets provide security during the whole protocol by univocally linking each registering user with a single request.

The eIDAS Regulation: A Survey of Technological Trends for European Electronic Identity Schemes

The eIDAS regulation aims to provide an interoperable European framework to enable EU citizens to authenticate and communicate with services of other Member States by using their national electronic identity. While a number of high-level requirements (e.g., related to privacy and security) are established to make interoperability among Member States possible, the eIDAS regulation does not explicitly specify the technologies that can be adopted during the development phase to meet the requirements as mentioned earlier. To the best of our knowledge, there is no work available in the literature investigating the technological trends within the notified eIDAS electronic identity schemes used by Member States. To fill this gap, this paper analyzes how the different technological trends of notified schemes satisfy the requirements of the eIDAS regulation. To do this, we define a set of research questions that allow us to investigate the correlations between different design dimensions such as security, privacy, and usability. Based on these findings, we provide a set of lessons learned that would be valuable to the security community, as they can provide useful insights on how to more efficiently protect interoperable national digital identities. Furthermore, we provide a brief overview regarding the new eIDAS regulation (eIDAS 2.0) that aims to provide a more privacy-preserving electronic identity solution by moving from a centralized approach to a decentralized one

The State of the Electronic Identity Market: Technologies, Infrastructure, Services and Policies

Authenticating onto systems, connecting to mobile networks and providing identity data to access services is common ground for most EU citizens, however what is disruptive is that digital technologies fundamentally alter and upset the ways identity is managed, by people, companies and governments. Technological progress in cryptography, identity systems design, smart card design and mobile phone authentication have been developed as a convenient and reliable answer to the need for authentication. Yet, these advances ar enot sufficient to satisfy the needs across people's many spheres of activity: work, leisure, health, social activities nor have they been used to enable cross-border service implementation in the Single Digital Market, or to ensure trust in cross border eCommerce. The study findings assert that the potentially great added value of eID technologies in enabling the Digital Economy has not yet been fulfilled, and fresh efforts are needed to build identification and authentication systems that people can live with, trust and use. The study finds that usability, minimum disclosure and portability, essential features of future systems, are at the margin of the market and cross-country, cross-sector eID systems for business and public service are only in their infancy. This report joins up the dots, and provides significant exploratory evidence of the potential of eID for the Single Digital Market. A clear understanding of this market is crucial for policy action on identification and authentication, eSignature and interoperability.JRC.DDG.J.4-Information Societ

Formal verification of secondary authentication protocol for 5G secondary authentication

The Fifth-Generation mobile network (5G) will enable interconnectivity between the Home Network (HN) and Data Network (DN) whereby mobile users with their User Equipment (UE) will be able to access services provided by external Service Providers (SP) seamlessly. The mobile user and SP will rely on security assurances provided by authentication protocols used. For 5G, primary authentication between the UE and the HN has been defined and specified by the Third Generation Partnership Project (3GPP) while the secondary authentication has also been defined but not specified. 3GPP recommends the Extensible Authentication Protocol (EAP) framework for secondary authentication between the UE and the SP. However, the secondary authentication methods have not been formally verified, so this paper proposes a Secondary Authentication Protocol (SAP) for service authentication and provides a comprehensive formal analysis using ProVerif a security protocol verifier. Finally, it conducts a security analysis on the protocol's security properties

Strong Electronic Identification: Survey & Scenario Planning

The deployment of more high-risk services such as online banking and government services on the Internet has meant that the need and demand for strong electronic identity is bigger today more than ever. Different stakeholders have different reasons for moving their services to the Internet, including cost savings, being closer to the customer or citizen, increasing volume and value of services among others. This means that traditional online identification schemes based on self-asserted identities are no longer sufficient to cope with the required level of assurance demanded by these services. Therefore, strong electronic identification methods that utilize identifiers rooted in real world identities must be provided to be used by customers and citizens alike on the Internet. This thesis focuses on studying state-of-the-art methods for providing reliable and mass market strong electronic identity in the world today. It looks at concrete real-world examples that enable real world identities to be transferred and used in the virtual world of the Internet. The thesis identifies crucial factors that determine what constitutes a strong electronic identity solution and through these factors evaluates and compares the example solutions surveyed in the thesis. As the Internet become more pervasive in our lives; mobile devices are becoming the primary devices for communication and accessing Internet services. This has thus, raised the question of what sort of strong electronic identity solutions could be implemented and how such solutions could adapt to the future. To help to understand the possible alternate futures, a scenario planning and analysis method was used to develop a series of scenarios from underlying key economic, political, technological and social trends and uncertainties. The resulting three future scenarios indicate how the future of strong electronic identity will shape up with the aim of helping stakeholders contemplate the future and develop policies and strategies to better position themselves for the future
