Remote attestation mechanism for embedded devices based on physical unclonable functions

Remote attestation mechanisms are well studied in the high-end computing environments; however, the same is not true for embedded devices-especially for smart cards. With ever changing landscape of smart card technology and advancements towards a true multi-application platform, verifying the current state of the smart card is significant to the overall security of such proposals. The initiatives proposed by GlobalPlatform Consumer Centric Model (GP-CCM) and User Centric Smart Card Ownership Model (UCOM) enables a user to download any application as she desire-depending upon the authorisation of the application provider. Before an application provider issues an application to a smart card, verifying the current state of the smart card is crucial to the security of the respective application. In this paper, we analyse the rationale behind the remote attestation mechanism for smart cards, and the fundamental features that such a mechanism should possess. We also study the applicability of Physical Unclonable Functions (PUFs) for the remote attestation mechanism and propose two algorithms to achieve the stated features of remote attestation. The proposed algorithms are implemented in a test environment to evaluate their performance. © 2013 The authors and IOS Press. All rights reserved

Proposing a secure component-based-application logic and system’s integration testing approach

Software engineering moved from traditional methods of software enterprise applications to com-ponent based development for distributed system’s applications. This new era has grown up forlast few years, with component-based methods, for design and rapid development of systems, butfact is that , deployment of all secure software features of technology into practical e-commercedistributed systems are higher rated target for intruders. Although most of research has been con-ducted on web application services that use a large share of the present software, but on the otherside Component Based Software in the middle tier ,which rapidly develops application logic, alsoopen security breaching opportunities .This research paper focus on a burning issue for researchersand scientists ,a weakest link in component based distributed system, logical attacks, that cannotbe detected with any intrusion detection system within the middle tier e-commerce distributed ap-plications. We proposed An Approach of Secure Designing application logic for distributed system,while dealing with logically vulnerability issue

TCG based approach for secure management of virtualized platforms: state-of-the-art

There is a strong trend shift in the favor of adopting virtualization to get business benefits. The provisioning of virtualized enterprise resources is one kind of many possible scenarios. Where virtualization promises clear advantages it also poses new security challenges which need to be addressed to gain stakeholders confidence in the dynamics of new environment. One important facet of these challenges is establishing 'Trust' which is a basic primitive for any viable business model. The Trusted computing group (TCG) offers technologies and mechanisms required to establish this trust in the target platforms. Moreover, TCG technologies enable protecting of sensitive data in rest and transit. This report explores the applicability of relevant TCG concepts to virtualize enterprise resources securely for provisioning, establish trust in the target platforms and securely manage these virtualized Trusted Platforms
