Summary: Smart home is an important IoT-based application for improving living environment. To ensure data confidentiality, many cryptographic protection schemes have been proposed. Access control is a promising method to protect generated data from unauthorized access and is urgently needed in smart home. This study proposes a decentralized and reliable access control scheme for smart homes using smart contracts, named DAC4SH. By recording all access activities into immutable distributed ledgers for auditing, our proposed scheme proves to be feasible. According to experimental results, the performance of DAC4SH is deemed appropriate.

Summary: The extensive application of IoT and AI technology has greatly promoted the construction and development of smart cities. However, the privacy and data security of smart home users accessing the system through public channels are vulnerable to attack. This paper presents a provably secure authentication scheme for the smart home environment, ensuring only legitimate users can use smart devices. The scheme is verified using an informal model and formally analyzed using the Real or Random model. By comparing security and performance analysis, our scheme proves to have higher security with similar performance.

Summary: The upcoming paradigm in Internet of Things (IoT) based applications aims to improve interactional communication strategies between devices in smart home systems. Security measures, such as authentication and access control, are vital to ensure secure communication. The proposed protocol, Modified Honey Encryption using Inverse Sampling-Conditional Probability Model Transform (MHE-IS-CPMT) with Elliptic Curve Cryptography (ECC), provides secure authentication and key agreement. It includes steps such as initialization, registration, login and data access request, authentication and session key agreement, and key update. The protocol ensures secure device registration, user authentication, and key management, offering greater security than existing methods.

Summary: Devices and edges of the IoT work together to enhance sensing capability, causing increased concern for protecting personal sensory information privacy in smart homes. Attribute-based encryption (ABE) is widely used to enable secure data sharing in this scenario. However, the computational complexity of ABE makes it difficult for resource-constrained devices. Edge computing solves this problem by offloading heavy cryptographic operations to an edge server (ES) and uploading device data to a cloud. To ensure data integrity and correctness, a lightweight dual auditing scheme is proposed, utilizing data block aggregation, signatures, and Zero-Knowledge (ZK) proof. A smart contract is used for data user authentication to prevent collusion attacks. Simulation experiments confirm the efficiency of the proposed multiple auditing scheme.

Summary: Smart home devices are susceptible to various attacks, especially when multiple devices collude to launch a DDoS attack in a network. Previous studies have proposed authentication protocols that are not necessarily implementable in devices, particularly during D2D interactions. This research utilizes the Ethereum blockchain and smart contracts to propose a lightweight authentication mechanism that enables secure D2D interactions in a smart home.
