TL;DR
A flexible privacy-preserving framework that combines the scalability of broadcast encryption with the fine-grained access control of Attribute-Based Encryption through a novel pseudo-layer encryption model, and achieves confidentiality, forward and backward secrecy, and collusion resistance.
Experimental results from a full-scale prototype, comprising ESP32-based devices and Android apps, demonstrate that SHERLOC incurs millisecond-level latency and maintains compatibility with legacy MQTT brokers without altering protocol semantics, making it a robust and deployable solution for modern smart home environm...
A privacy-preserving, secure data-sharing framework tailored for edge-cloud collaborative architectures that minimizes the computational overhead on the terminal side while safeguarding user privacy, and effectively reduces the overhead associated with user joining and revocation within the same group.
The consumer Internet of Things (CIoT) enables large-scale sensing and data-driven services by connecting billions of devices. However, the privacy-preserving data aggregation in mobile edge computing (MEC)-enabled CIoT remains challenging when the edge aggregator is malicious, rather than simply honest-but-curious. Sp...
A flexible credential model that employs vector commitments with a padding strategy to unify credentials from heterogeneous issuers, enabling privacy-preserving authentication without enforcing a global static attribute set or verifier-defined policies is proposed.
This paper proposes ABEAT, an efficient and anonymous dynamic group communication system that also minimizes overhead on receivers who are not the intended recipients of a message, and proposes a new anonymous KP-ABE approach to maintain recipient anonymity.
In this paper, a behaviour-sensitive session orchestration architecture over secure communication and the rationale behind it will be proposed and discussed, which is a variant of mixed public-key cryptography that aims at offering more manageable, secret, and authenticity in real-time messaging infrastructure. The arc...
