A Proxy-Based Encrypted Online Social Network With Fine-Grained Access

TL;DR

This paper introduces a proxy-based encrypted social network that enables users to control access to individual pieces of information and create protected circles with encrypted sharing, enhancing privacy and access control.

Contribution

It presents a novel proxy-based encryption scheme allowing fine-grained access control and secure sharing within social networks, addressing limitations of traditional platforms.

Findings

Enables user-specific access control for shared information.

Supports creation of protected circles with encrypted sharing.

Uses proxy-based key distribution for secure access management.

Abstract

When using Online Social Networks, users often share information with different social groups. When considering the backgrounds of the groups there is often no or little intersection within the members. This means that a user who shares information often has to share it with all members of all groups. It can be problematic that the user cannot decide which group sees which information. Our approach therefore, allows users to decide for every bit of information who can access it. Further, protected circles can be created, where users can share information within. Shared information and circles are encrypted and the keys can be distributed by proxies.
