공동주택의 AI IoT의 하자로 인한 민사책임에 대한 소고

In contemporary South Korea, the ubiquitous presence of smartphones has become ingrained in the daily lives of its populace. With artificial intelligence permeating various aspects of modern living, from smart vehicles to interconnected homes, the integration of IoT devices has become the norm. Initially conceived for security purposes, entrance keypads now serve as pivotal nodes within home networks, interconnected with the broader Internet of Things ecosystem. However, these keypads, while designed to enhance convenience, also harbor significant volumes of personal data, raising concerns over potential breaches and leaks. Indeed, instances of personal data exposure on the dark web, stemming from IoT hacking incidents, underscore the critical imperative for robust security measures. To fortify the security framework surrounding these keypads and mitigate potential risks within residential complexes, a comprehensive legislative review is warranted. This examination encompasses the classification of keypad-related disputes as 'defects' and the subsequent application of pertinent statutes such as the 'Housing Act.' Given the intricate interplay between various legal frameworks governing housing complexes, scrutiny of relevant articles within the 'Civil Code' and the 'Act on Ownership and Management of Condominium Buildings,' particularly Articles 667 and 668, is essential to establish a coherent legal foundation. Moreover, the regulatory landscape must extend to encompass the 'Personal Information Protection Act,' addressing the ramifications of personal data exposure through IoT vulnerabilities. Furthermore, in light of IoT's alignment with the 'Installation and Technical Standards for Intelligent Home Networks,' delineating precise definitions and standards governing home networks becomes imperative. This necessitates a thorough appraisal of existing legislation pertaining to cybersecurity and hacking incidents, with a specific focus on enhancing security protocols surrounding keypad systems in residential settings. Proposals for legislative amendments, such as revisions to select provisions within the 'Enforcement Decree of the Information and Communication Business Act,' aim to codify stringent standards and safeguards within our legal framework. Additionally, recognizing the global nature of IoT technology standards and the inherent challenges posed by its rapid evolution, proactive measures are requisite. This includes advocating for amendments enabling management bodies to engage specialized supervisors through contractual arrangements or direct employment, thereby ensuring adept oversight and compliance in an ever-evolving technological landscape.

Certificateless Authentication Scheme Based on Blockchain in Smart Home Network

The traditional centralized intelligent home network security authentication schemes have security problems such as integrity and confidentiality, while the distributed schemes have the problem of delayed authentication. These schemes are not suitable for the intelligent home environment of edge computing. To solve these problems, a certificateless smart home network authentication scheme based on blockchain and certificateless cryptosystem is proposed to realize mutual authentication among users, intelligent terminals (ITs), and intelligent gateways (IGs). The aggregation signature scheme of certificateless identity is introduced into the authentication of intelligent terminals in smart home network. The IG only needs to generate a signature to complete the identity authentication of multiple ITs. Compared with other authentication schemes, the security verification and performance analysis show that the proposed scheme uses less computation overhead and achieves more security features.

Enhanced Dynamic Bandwidth Allocation Algorithm for Intelligent Home Networks

Internet of Things (IoT) has been seen playing a tremendous change in the Information Technology (IT) environments, and thus its importance has also been realized and played a vital role within Intelligent Home Networks (IHNs). This is because IoT establishes a connection between things and the Internet by utilizing different sensing devices to implement the intelligence to deal with the identification and management of the connected things. IHNs use intelligent systems to perform their daily operations. Meanwhile, these networks ensure comfort, safety, healthcare, automation, energy conservation, and remote management to devices and users. Apart from that, these networks provide assistance in self-healing for faults, power outages, reconfigurations, and more. However, we have realized that more and advanced devices and services continue to be introduced and used in these networks. This has led to competitions of the limited available network resources, services, and bandwidth. In this paper, therefore, we present the design and implementation of a Novel Dynamic Bandwidth Allocation (NoDBA) algorithm to solve the performance bottleneck incurred with IHNs. The proposed algorithm deals with the management of bandwidth and its allocation. In the proposed algorithm, this study integrates two algorithms, namely; Offline Cooperative Algorithm (OCA) and Particle Swarm Optimization (PSO) to improve Quality of Service (QoS). PSO defines the priority limits for subnets and nodes in the network. Meanwhile, OCA facilitates dynamic bandwidth allocation in the network. The Network Simulator-2 (NS-2) was used to simulate and evaluate the NoDBA and it showed improved results compared to the traditional bandwidth allocation algorithms. The obtained results show an average throughput of 92%, average delay of 0.8 seconds, and saves energy consumption of 95% compared to Dynamic QoS-aware Bandwidth Allocation (DQBA) and Data-Driven Allocation (DDA). Keywords: IHNs, Dynamic Bandwidth Allocation, PSO, OCA, QoS

Smart home is an intelligent home network whose services and infrastructure are based information and communication technology. It is an intelligent use of wireless technology for the implementation of automated home electrical/electronic appliances and devices, domestic tasks, and security devices, for the wellbeing of the occupant. However, the development of smart homes has focused mainly on building for the young and able-bodied persons for the purpose of enhancing home comfort, energy saving, and security, without considering the aged and disabled persons in Africa. The Smart Home System were implemented in existing home environments, with the automation focusing on recognition of voice commands and uses low-power RF wireless communication modules along with a microcontroller for message passing. The system consists of voice recognition module for voice input and recognition. The control signal of the recognized command is transmitted to the microcontroller, and the microcontroller uses this signal to control home appliances. The designed system was tested and the result showed that the level of system response is higher in dead home than in a live home, hence, the system performance is affected by the environmental noise and the accents of un-trained aged persons are not supported by it. This system is most suitable for the aged and the disabled persons living alone and is intended to control all lights and electrical appliances inside a house using voice commands. In this work a home automation control system based on voice recognition was designed, implemented and experimental tests done and results were obtained.

Design of Authentication Model Preserving Intimacy and Trust in Intelligent Environments

With the recent advances in communication technologies for low-power devices, pervasive computing environments (PCE) spread as new domains beyond legacy enterprise and personal computing. The intelligent home network environment is thing which invisible device that is not shown linked mutually through network so that user may use device always is been pervasive. Smart devices are interconnected and collaborate as a global distributed system to infuse intelligence into systems and processes. This kind of environment provides various smart services and makes consequently an offer of convenient, pleasant, and blessed lives to people. However, the risk is high as long as the offer is pleasant and convenient. In such context, security is stil very fragile and there is often a violation of user privacy and service interference. For this, a special interest in ubiquitous network security is going up. Safety lies primarily in the authentication of users accessing the network. It guarantees that only legitimate users can login and access to services indoor the network. In this paper, we propose an anonymous authentication and access control scheme to secure the interaction between mobile users handling smart devices and smart services in PCEs. In an environment based on public key infrastructure (PKI) and Authentication, Authorization, and Accounting (AAA), the proposed authentication protocol combines both network authentication technique based on symmetric keys and single sign-on mechanisms. The authentication protocol is simple and secure, protects the privacy of user and aims to satisfy the security requirements.

DynTunKey: a dynamic distributed group key tunneling management protocol for heterogeneous wireless sensor networks

Wireless sensor networks (WSNs) are being used for many applications ranging from mobile target surveillance to intelligent home networking. Due to the sensitive nature of the data transmitted by these applications, appropriate protection mechanisms are needed to prevent attackers from exploiting the weaknesses of the radio links. In this paper, we propose a novel group key management scheme called DynTunKey (dynamic tunneling and group key management protocol). This paper investigates the use of secure tunnels as a solution to improve the protection of WSNs. We propose a tunneling scheme that conforms to the security requirements of WSNs while having less computational and network overhead. We also propose a solution for a dynamic integration in the secured communication of a newly deployed sensor. A set of experiments has been conducted to assess the performance of the proposed scheme with regard to recent key management protocol and to traditional tunnels built using the IPSec protocol. We found that our protocol considerably reduces the number of transmitted messages as well as the computational load, which makes it suitable for WSNs. We tested the proposed protocol considering two models of mobility of the targets which are respectively the Random Walk model and the Gauss Markov model.
