New Secure Solutions For Privacy And Access Control In Health Information Exchange, Ahmed Fouad Shedeed Ibrahim
New Secure Solutions For Privacy And Access Control In Health Information Exchange, Ahmed Fouad Shedeed Ibrahim
Theses and Dissertations--Computer Science
In the current digital age, almost every healthcare organization (HCO) has moved from storing patient health records on paper to storing them electronically. Health Information Exchange (HIE) is the ability to share (or transfer) patients’ health information between different HCOs while maintaining national security standards like the Health Insurance Portability and Accountability Act (HIPAA) of 1996. Over the past few years, research has been conducted to develop privacy and access control frameworks for HIE systems. The goal of this dissertation is to address the privacy and access control concerns by building practical and efficient HIE frameworks to secure the sharing …

Construction Of Efficient Authentication Schemes Using Trapdoor Hash Functions, Santosh Chandrasekhar
University of Kentucky Doctoral Dissertations
In large-scale distributed systems, where adversarial attacks can have widespread impact, authentication provides protection from threats involving impersonation of entities and tampering of data. Practical solutions to authentication problems in distributed systems must meet specific constraints of the target system, and provide a reasonable balance between security and cost. The goal of this dissertation is to address the problem of building practical and efficient authentication mechanisms to secure distributed applications. This dissertation presents techniques to construct efficient digital signature schemes using trapdoor hash functions for various distributed applications. Trapdoor hash functions are collision-resistant hash functions associated with a secret trapdoor …
