Reliable and Privacy-Preserving Wireless Body-Area Sensor Networks for E-Health Monitoring

NSERC Collaborative Research and Development Grant $540000

2012-04-01

Healthcare costs have been skyrocketing as the baby boom generation continues to grey. Remote e-health monitoring has shown to be promising for decreasing emergency room visits and/or hospitalizations compared to standard traditional healthcare. With the advancement of wireless communications and networking technology, wireless sensor networks on human body are emerging as a promising new approach for monitoring patient health and disease progression. As co-investigator of this three-year research project, Dr. Lin focused on the development of wireless body area networks for e-healthcare applications, and helped design and develop a new set of networking solutions for power-efficient, reliable, and privacy-preserving communications, taking into account the unique propagation characteristics and strict networking performance requirements.

A Threshold Anonymous Authentication Protocol for VANETs
IEEE Transactions on Vehicular Technology

2016-03-01

Vehicular ad hoc networks (VANETs) have recently received significant attention in improving traffic safety and efficiency. However, communication trust and user privacy still present practical concerns to the deployment of VANETs, as many existing authentication protocols for VANETs either suffer from the heavy workload of downloading the latest revocation list from a remote authority or cannot allow drivers on the road to decide the trustworthiness of a message when the authentication on messages is anonymous. In this paper, to cope with these challenging concerns, the authors propose a new authentication protocol for VANETs in a decentralized group model by using a new group signature scheme.

An Empirical Investigation into Path Divergences for Concolic Execution Using CREST
Security and Communication Networks

2015-12-01

Recently, concolic execution has become a hotspot in the domain of software testing and program analysis. However, a practical challenge, called path divergence, impairs the soundness and completeness of concolic execution. A path divergence indicates the tested program runs an unpredicted path. In this work, we carry out a comprehensive empirical study on path divergences using an open-source concolic execution tool, named CREST. To make the investigation representative, we select 120 test units randomly from 21 different open-source programs.

PPDM: A Privacy-Preserving Protocol for Cloud-Assisted e-Healthcare Systems
IEEE Journal of Selected Topics in Signal Processing

2015-09-01

E-healthcare systems have been increasingly facilitating health condition monitoring, disease modeling and early intervention, and evidence-based medical treatment by medical text mining and image feature extraction. Owing to the resource constraint of wearable mobile devices, it is required to outsource the frequently collected personal health information (PHI) into the cloud. Unfortunately, delegating both storage and computation to the untrusted entity would bring a series of security and privacy issues. The existing work mainly focused on fine-grained privacy-preserving static medical text access and analysis, which can hardly afford the dynamic health condition fluctuation and medical image analysis. In this paper, a secure and efficient privacy-preserving dynamic medical text mining and image feature extraction scheme PPDM in cloud-assisted e-healthcare systems is proposed.

User-Provided Networking for QoE Provisioning in Mobile Networks
IEEE Wireless Communications

2015-08-01

With the accelerating pace of development in mobile networks, mobile network operators and service providers are facing new challenges, especially in terms of quality of experience provisioning. To address these challenges, we present a new network paradigm by taking advantage of an emerging type of user-provided network. In particular, the proposed scheme allows end users to play a crucial role in both QoE evaluation and network improvement. Some points for possible challenges and future research are given. Also, a case study with the proposed resource scheduling algorithm is conducted to illustrate the win-win situation created by the proposed network paradigm.

An Effective Behaviour-Based Android Malware Detection System
Security and Communication Networks

2015-08-01

With the rapid growth of Android applications and malware, it has become a challenge to distinguish malware from a huge number of applications. The use of behavioral analytics is one of the most promising approaches because of its accuracy and resilience to malware variants. In this paper, we propose a behavior-based malware detection system.

White-Box Traceable Ciphertext-Policy Attribute-Based Encryption Supporting Flexible Attributes
IEEE Transactions on Information Forensics and Security

2015-06-01

In this paper, we propose two practical large universe CP-ABE systems supporting white-box traceability. Compared with existing systems, both the two proposed systems have two advantages: 1) the number of attributes is not polynomially bounded and 2) malicious users who leak their decryption keys could be traced. Moreover, another remarkable advantage of the second proposed system is that the storage overhead for traitor tracing is constant, which are suitable for commercial applications.

PSMPA: Patient Self-Controllable and Multi-Level Privacy-Preserving Cooperative Authentication in Distributedm-Healthcare Cloud Computing System
IEEE Transactions on Parallel and Distributed Systems

2015-06-01

Distributed m-healthcare cloud computing system significantly facilitates efficient patient treatment for medical consultation by sharing personal health information among healthcare providers. However, it brings about the challenge of keeping both the data confidentiality and patients’ identity privacy simultaneously. Many existing access control and anonymous authentication schemes cannot be straightforwardly exploited. To solve the problem, in this paper, a novel authorized accessible privacy model (AAPM) is established.

Duth: A User-Friendly Dual-Factor Authentication for Android Smartphone Devices
Security and Communication Networks

2015-05-01

With the pervasiveness of smartphones and the richness of mobile apps, many people are storing increasingly sensitive data on them, in greater quantities. In order to protect this sensitive information from misuse due to loss, or other accidental reasons, strong smartphone authentication has become imperative and has received considerable attention in recent years. However, when we directly implement traditional authentication schemes in smartphone devices, the balance between security and user-friendliness of authentication becomes challenging, mainly because of the input-in-motion environments. In this paper, without adding extra hardware devices, we present a user-friendly, dual-factor authentication scheme called Duth, for Android smartphone devices.

LSR: Mitigating Zero-day Sybil Vulnerability in Privacy-preserving Vehicular Peer-to-Peer Networks
IEEE Journal on Selected Areas of Communications

2013-09-01

Privacy-preserving Vehicular Peer-to-Peer Network (VPNET) is particularly vulnerable to sybil attack, where a malicious vehicle can abuse its multiple unlinkable pseudo-IDs to pretend multiple and distinct vehicles in the network. To make the matter even worse, due to the privacy-preserving network environment, zero-day sybil vulnerability is hard to defend against, i.e., a vehicle cannot locally detect a sybil attacker before the attacker is formally revoked. In this paper, aiming at mitigating zero-day sybil vulnerability in privacy-preserving VPNET, we propose an efficient Local Sybil Resistance scheme, called LSR, to locally detect sybil attack.
