A Hybrid Blockchain-Edge Architecture for Electronic Health Records Management with Attribute-based Cryptographic Mechanisms
Hao Guo, Wanxin Li, Mark Nejad +1
This paper presents a hybrid blockchain-edge architecture for managing Electronic Health Records (EHRs) with attribute-based cryptographic mechanisms. The architecture introduces a…
Attribute-based Multi-Signature and Encryption for EHR Management: A Blockchain-based Solution
Hao Guo, Wanxin Li, Ehsan Meamari +2
The global Electronic Health Record (EHR) market is growing dramatically and has already hit $31.5 billion in 2018. To safeguard the security of EHR data and privacy of patients, f…
Collusion Attacks on Decentralized Attributed-Based Encryption: Analyses and a Solution
Ehsan Meamari, Hao Guo, Chien-Chung Shen +1
Attribute-based Encryption (ABE) is an information centric security solution that moves beyond traditional restrictions of point-to-point encryption by allowing for flexible, fine-…
Data User-Based Attribute-Based Encryption
Ehsan Meamari, Hao Guo, Chien-Chung Shen +1
Attribute-Based Encryption (ABE) has emerged as an information-centric public-key cryptographic system which allows a data owner to share data, according to access policy, with mul…
Access Control for Electronic Health Records with Hybrid Blockchain-Edge Architecture
Hao Guo, Wanxin Li, Mark Nejad +1
The global Electronic Health Record (EHR) market is growing dramatically and expected to reach $39.7 billions by 2022. To safe-guard security and privacy of EHR, access control is…
Multi-Authority Attribute-Based Access Control with Smart Contract
Hao Guo, Ehsan Meamari, Chien-Chung Shen
Attribute-based access control makes access control decisions based on the assigned attributes of subjects and the access policies to protect objects by mediating operations from t…
Location-Enhanced Authenticated Key Exchange
Marcos Portnoi, Chien-Chung Shen
We introduce LOCATHE (Location-Enhanced Authenticated Key Exchange), a generic protocol that pools location, user attributes, access policy and desired services into a multi-factor…
Secure Zones: An Attribute-Based Encryption advisory system for safe firearms
Marcos Portnoi, Chien-Chung Shen
This work presents an application of the highly expressive Attribute-Based Encryption to implement Secure Zones for firearms. Within these zones, radio-transmitted local policies b…
Location-aware sign-on and key exchange using attribute-based encryption and Bluetooth beacons
Marcos Portnoi, Chien-Chung Shen
This work presents a mobile sign-on scheme, which utilizes Bluetooth Low Energy beacons for location awareness and Attribute-Based Encryption for expressive, broadcast-style key ex…
Wireless-Delimited Secure Zones with Encrypted Attribute-Based Broadcast for Safe Firearms
Marcos Portnoi, Chien-Chung Shen
This work presents an application of the highly expressive Attribute-Based Encryption to implement wireless-delimited Secure Zones for firearms. Within these zones, radio-transmitt…
Loc-Auth: Location-Enabled Authentication Through Attribute-Based Encryption
Marcos Portnoi, Chien-Chung Shen
Traditional user authentication involves entering a username and password into a system. Strong authentication security demands, among other requirements, long, frequently hard-to-…
