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…
An information services algorithm to heuristically summarize IP addresses for a distributed, hierarchical directory service
Marcos Portnoi, Jason Zurawsky, Martin Swany
A distributed, hierarchical information service for computer networks might rely in several instances, located in different layers. A distributed directory service, for example, mi…
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-…
