Multimedia Internet of Things: A Comprehensive Survey <s> 5) SECURITY BASED ARCHITECTURE <s> Abstract.Multicast is an internetwork service that provides efficient delivery of data from a source to multiple receivers. It reduces the bandwidth requirements of the network and the computational overhead of the host devices. This makes multicast an ideal technology for communication among a large group of participants. Secure group communications involves many service types include teleconferencing, pay TV and real-time delivery of stock quotes. IP multicast is the traditional mechanism to support multicast communications. Multicast security includes group membership control, secure key distribution, secure data transfer and copyright protection. This paper is an overview of the schemes proposed for group key management, authentication and watermarking in wired networks with fixed members and wireless networks with mobile members. <s> BIB001 </s> Multimedia Internet of Things: A Comprehensive Survey <s> 5) SECURITY BASED ARCHITECTURE <s> There is a critical need to provide privacy and security assurances for distributed multimedia sensor networking in applications including military surveillance and healthcare monitoring. Such guarantees enable the widespread adoption of such information systems, leading to large-scale societal benefit. To effectively address protection and reliability issues, secure communications and processing must be considered from system inception. Due to the emerging nature of broadband sensor systems, this provides fertile research ground for proposing more paradigm-shifting approaches. This paper discusses issues in designing for security and privacy in distributed multimedia sensor networks. We introduce the heterogeneous lightweight sensornets for trusted visual computing framework for distributed multimedia sensor networks. Protection issues within this architecture are analyzed, leading to the development of open research problems including secure routing in emerging free-space optical sensor networks and distributed privacy for vision-rich sensor networking. Proposed solutions to these problems are presented, demonstrating the necessary interaction among signal processing, networking, and cryptography. <s> BIB002 </s> Multimedia Internet of Things: A Comprehensive Survey <s> 5) SECURITY BASED ARCHITECTURE <s> This paper presents a state-of-the-art overview of distinguishable approaches, overview of some writings that have themes and a similar discussion, with the background to provide an overview to the readers of control and things related to multimedia information security, all attempting to define multimedia information security architecture, followed by a proposition of requirements for multimedia integrated security architecture.

In this work, we design a new and efficient media-aware security framework for facilitating various multimedia applications in the Internet of Things. First, we present a novel multimedia traffic classification and analysis method for handling the heterogeneity of diverse applications. Then a media-aware traffic security architecture is proposed based on the given traffic classification to enable various multimedia services being available anywhere and anytime. Furthermore, we provide a design rule and strategy to achieve a good trade-off between a system?s flexibility and efficiency. To the best of our knowledge, this study is the first to provide general media-aware security architecture by jointly considering the characteristics of multimedia traffic, security service, and the Internet of Things. <s> BIB005
Zhou and Chao BIB005 devised Mediaware Traffic Security Architecture (MTSA) for M-IoT based on four main components. These components are key management which comprises service control, user control, flow control scalable, and nonscalable schemes BIB002 . Batch rekeying accommodates multiple multimedia applications based on periodic batch keying, periodic batch leave keying, and periodic batch join rekeying BIB003 . Authentication is achieved by group authentication, source authentication, and individual sender authentication employing access control list, ability certificates, and mutual authentication methods BIB004 . Watermarking is used to identify the origin of multimedia content, trace illegal distribution, and block unauthorized access by embedding a unique watermark into multimedia content BIB001 . The proposed framework exploits visual secrecy measures to provide generic multimedia security solutions that degrade comparatively to the number of shares in possession of an attacker. MTSA inherits content-awareness characteristics from media-aware based middleware security architecture for multimedia services BIB004 .
