Visible to the public CRII: SaTC: Hardware based Authentication and Trusted Platform Module functions (HAT) for IoTs

Crucial and critical needs of security and trust requirements are growing in all classes of applications such as in automobiles and for wearable devices. Traditional cryptographic primitives are computation-intensive and rely on secrecy of shared or session keys, applicable on large systems like servers and secure databases. This is unsuitable for embedded devices with fewer resources for realizing sufficiently strong security. This research addresses new hardware-oriented capabilities and mechanisms for protecting Internet of Things (IoT) devices.

Visible to the public TWC: Small: Collaborative: Towards Privacy Preserving Online Image Sharing

On-line sharing of images has become a key enabler of users' connectivity. Various types of images are shared through social media to represent users' interests and experiences. While extremely convenient and socially valuable, this level of pervasiveness introduces acute privacy concerns. First, once shared images may go anywhere, as copying / resharing images is straightforward. Second, the information disclosed through an image reveals aspects of users' private lives, affecting both the owner and other subjects in the image.

Visible to the public SaTC: TTP: Medium: Collaborative: RESULTS: Reverse Engineering Solutions on Ubiquitous Logic for Trustworthiness and Security

Due to the globalization of the integrated circuit (IC) supply chain, the reduction of manufacturing costs and the need for shorter time to market, commercial-off-the-shelf ICs are now prevalent in modern electronic systems. However, the wide usage of such components breeds major security and trust concerns. Validating the security and trustworthiness of these components is extremely challenging since the end user does not have access to the design details.

Visible to the public CRII: SaTC: Automated Proof Construction and Verification for Attribute-based Cryptography

This project develops a comprehensive proof construction and verification framework for a well-defined class of cryptographic protocols: attribute-based cryptosystems. In particular, existing automated proof construction and verification frameworks, such as EasyCrypt and CryptoVerif, are extended to provide support for attribute-based cryptography. The extensions consist of libraries of simple transformations, algebraic manipulations, commonly used abstractions and constructs, and proof strategies, which will help in generation and verification of proofs in attribute-based cryptography.

Visible to the public CIF:Small:Collaborative Research:Security in Dynamic Environments: Harvesting Network Randomness and Diversity

The project aims at quantifying a general network's inner potential for supporting various forms of security by achieving secret common randomness between pairs or groups of its nodes. Statistical and computational secrecy measures are being considered against a general passive adversary. Common-randomness-achieving protocols are classified into two groups: culture-building and crowd-shielding. The former achieves common randomness between nodes situated in close proximity of each other, from correlated observations of specific (natural or induced) network phenomena.

Visible to the public SHF: Medium: PRISM: Platform for Rapid Investigation of efficient Scientific-computing & Machine-learning

Today's systems demand acceleration in processing and learning using massive datasets. Unfortunately, because of poor energy scaling and power limits, performance and power improvements due to technology scaling and instruction level parallelism in general-purpose processors have ended. It is well known that full custom, application-specific hardware accelerators can provide orders-of-magnitude improvements in energy/op for a variety of application domains.

Visible to the public CT-T: Modeling and Analyzing Trust in Service-Oriented Architectures

Service-oriented architectures (SOAs) enable the dynamic integration of services implemented on heterogeneous computer systems. An advantage of SOAs is that they provide high-level, semantically-rich services by abstracting the low-level details of their implementation. The availability of useful services such as Google's and Amazon's web service APIs has fostered applications that integrate a number of services to provide novel, more complex functionality.

Visible to the public CT-ISG: Collaborative Research: A Framework for the Modeling and Management of Obligations in Security Policies

The correct behavior and reliable operation of an information system relies not only on what users are permitted to do, but oftentimes on what users are required to do. Such obligatory actions are integral to the security procedures of many enterprises. The management o fobligations in security policies imposes significant technical challenges since obligations bear quite different properties from traditional access control. For example, obligations assigned to users often cannot be enforced.

Visible to the public Collaborative Research: CT-ISG: Error-resistant, Accountable, RFID-assisted Wireless Sensor Networks for Elder Cardiac Tele-Healthcare

Tele-healthcare could largely reduce national healthcare cost through remote self-managed patient monitoring. Cardiac Sensor Networks (CSNs) could be used to deploy such a system. Moreover, the integration of RFID into CSN could play an important role for elder healthcare because RFID could be used to monitor elders' medicine taking behaviors. On the other hand, the disclosure of RFID information during RFID tag-to-reader communications can cause the violation of patients' privacy. This research aims to achieve trustworthiness in a practical RFID-assisted CSN platform.
