The development of the wireless Internet environment enables smart devices to be interconnected in various environments to provide convenient services to users. Specifically, in connected vehicle and smart home, the infotainment system and home electronics are connected to the Internet to individually provide services to users. The connected vehicle uses the display panel to show users music, video, navigation, and so on desired, or to develop a service that reduces the burden of driving and allows other activities by autonomous vehicles. However, these services are designed and developed independently on the platform and are not suitable for the concept of residential space of the future society. In this article, we propose a smart life platform by combining the concepts of connected vehicle and smart home into one platform. It also provides the SLP-MCAF to provide secure services within the platform. The SLP-MCAF strongly reinforces the authentication of objects and introduces clusters to improve availability so that services are not separated from the automobile or home, and services are continuous. Through simulation, we demonstrate the stability and efficiency of the proposed platform.

Mobile users spend a tremendous amount of time surfing multimedia contents over the Internet to pursue their interests. A resource-constrained smart device demands more intensive computing tasks and lessens the battery life. To address the resource limitations (i.e., memory, lower maintenance cost, easier access, computing tasks) in mobile devices, mobile cloud computing is needed. Several approaches have been proposed to confront the challenges of mobile cloud computing, but difficulties still remain. However, in the coming years, context collecting, processing, and interchanging the results on a heavy network will cause vast computations and reduce the battery life in mobiles. In this paper, we propose a “context-based intelligent multimedia system” (CIMS) for ubiquitous cloud computing. The main goal of this research is to lessen the computing percentage, storage complexities, and battery life for mobile users by using pervasive cloud computing. Moreover, to reduce the computing and storage concerns in mobiles, the cloud server collects several groups of user profiles with similarities by executing K-means clustering on users’ data (context and multimedia contents). The distribution process conveys real-time notifications to smartphone users, according to what is stated in his/her profile. We considered a mobile cloud offloading system, which decides the offloading actions to/from cloud servers. Context-aware decision-making (CAD) customizes the mobile device performance with different specifications such as short response time and lesser energy consumption. The analysis says that our CIMS takes advantage of cost-effective features to produce high-quality information for mobile (or smart device) users in real time. Moreover, our CIMS lessens the computation and storage complexities for mobile users, as well as cloud servers. Simulation analysis suggests that our approach is more efficient than existing domains.

Recently, as vehicle computing technology has advanced, the paradigm of the vehicle has changed from a simple means of transportation to a smart vehicle for safety and convenience. In addition, the previous functions of the Intelligent Transportation System (ITS) such as traffic accident prevention and providing traffic volume information have been combined with cloud computing. ITS services provide user-oriented broad services in the Vehicular Cloud Computing (VCC) environment through efficient traffic management, traffic accident prevention, and convenience services. However, existing vehicle services focus on providing services using sensing information inside the vehicle and the system to provide the service through an interface with the external infrastructure is insufficient. In addition, because wireless networks are used in VCC environments, there is a risk of important information leakage from sensors inside the vehicle, such as driver personal identification and payment information at the time of goods purchase. We propose the VCC Service-oriented Security Framework (VCC-SSF) to address the limitations and security threats of VCC-based services. The proposed framework considers security for convenient and efficient services of VCC and includes new user-oriented payment management and active accident management services. Furthermore, it provides authentication, encryption, access control, confidentiality, integrity, and privacy protection for user personal information and information inside the vehicle.

Recently, intelligent transport systems have been applied to vehicle cloud environments. Such technology is especially useful for the systematic management of road traffic. Moreover, automobiles are increasingly equipped with a black box for accident prevention and preservation of evidence. Vehicle black boxes have become mandatory because black box images and voice data have served as forensic evidence in courts. However, the data from black boxes can be forged or modified by man-in-the-middle (MITM) attacks and message hijacking. In this paper, we propose a vehicle cloud computing-based black box service model that can provide integrity for black box data through digital signatures in vehicle cloud computing (VCC) environments. Our proposed model protects against MITM attacks and message hijacking using only a hash value and digital signature. Moreover, a mirroring technique (RAID 1) provides backup and recovery to protect the data from a traffic accident.

As intelligent ubiquitous devices become more popular, security threats targeting them are increasing; security is seen as one of the major challenges of the ubiquitous computing. Now a days, applying ubiquitous computing in number of fields for human safety and convenience was immensely increased in recent years. The popularity of the technology is rising day by day, and hence the security is becoming the main focused point with the advent and rising popularity of the applications. In particular, the number of wireless networks based on ubiquitous devices has increased rapidly; these devices support transmission for many types of data traffic. The convenient portability of ubiquitous devices makes them vulnerable to security threats, such as loss, theft, data modification, and wiretapping. Developers and users should seriously consider employing data encryption to protect data from such vulnerabilities. In this paper, we propose a Rhythm Key based Encryption scheme for ubiquitous devices (Ubi-RKE). The concept of Rhythm Key based Encryption has been applied to numerous real world applications in different domains. It provides key memorability and secure encryption through user touching rhythm on ubiquitous devices. Our proposed scheme is more efficient for users than existing schemes, by providing a strong cipher.

Due to computing power and advances of smart devices, recently uses of smart-phone have been rapidly increasing. Smart devices (smartphones and tablet PC etc.) threats such as a personal information leakage and fraudulent use of smart devices have also increased. So, effective measures are needed to address security issues of smart devices—authentication, access control, prevention from the attackers. In this paper, we proposed a rhythm-based user authentication scheme on smart devices. The proposed scheme complements the vulnerabilities of the existing schemes, and provides authentication that ensures availability. In additional, it provides stronger security and greater convenience.

Recently the interest in biometrics rises; voice recognition is highlighted in point that it does not restrict convenience, place and time of its use and is under the development by many organizations. This paper recommends the voice lock that provides the safety and the convenience in the use of smart-phone by utilizing the voice recognition technique and materializes its prototype. Also, it analyzes the current issues and discusses the use case scenario, etc.

Recently, phishing, a new type of crime, has increased due to the expansion of the use of smart phones, and financial losses have been increasingly reported. As damage cases, which have become sophisticated through the use of smart phones, crimes occurring in relation to smart phones are becoming a concern. In this paper, we discuss crimes such as phishing, voice phishing, and smishing, which can occur in a smart phone environment. In particular, we discuss the issue of smishing attacks, as well as the problems and preventive measures of these attacks.

Since the end of 2000, smartphones have explosively spread and have made people’s lives plentiful. With the start of smartphones, new smart devices, including tablet PCs, smart TVs, smart refrigerators, and smart air conditioners, have emerged, expanding their areas from individuals to business and home. These days, smart home service has drawn a lot of attention as a human-centric service. It is the environment where home appliances and other smart devices are connected to internet in order for user service and experience. The current smart home service is simply based on wireless home network to execute the function of connected home. The service has no smart home security so that it is possible for users to suffer a financial loss caused by information leakage or home appliance hacking. Therefore, to apply smart home service to surroundings, it is necessary to take into account security of smart devices. In this paper, we propose an enhanced security framework for smart devices in a smart home environment. The security framework provides the integrity system using the self-signing and access control techniques for preventing the security threats such as data modification, leakage and code fabrication.
