Internet of Things (IoT) is the new technological revolution that aspires to connect all the everyday physical objects to the Internet, making a huge global network of uniquely things which can share information amongst each other and complete scheduled tasks, bringing significant benefits to users and companies of a Smart City (SC). A Smart City represents a new future framework, which integrates multiple information and communication technology (ICT) and Internet of Things (IoT) solutions, so as to improve the quality life of its citizens. However, there are many security and privacy issues which must be taken into account before the official launching of this new technological concept. Many methods which focus on media security of wireless sensor networks have been proposed and can be adopted in the new expandable network of IoT. In this paper, we describe the upcoming IoT network architecture and its security challenges and analyze the most important researches on media security and privacy in wireless sensor networks (WSNs). Subsequently, we propose an Efficient algorithm for Media-based Surveillance System (EAMSuS) in IoT network for Smart City Framework, which merges two algorithms introduced by other researchers for WSN packet routing and security, while it reclaims the new media compression standard, High Efficiency Video Coding (HEVC). Experimental analysis shows the efficacy of our proposed scheme in terms of users' privacy, media security, and sensor node memory requirements. This scheme can be successfully integrated into the loT network of the upcoming Smart City concept. (C) 2017 Elsevier B.V. All rights reserved.

Many Internet security mechanisms depend on the use of cryptographic algorithms for various forms of authentication and confidentiality. Even when well-known and standardized cryptographic algorithms are used in well-known protocols, some parameters must be specified, the most important of which are usually algorithm identifiers and key or hash-output lengths. The author reviews some recent key length recommendations and compares those to current usage. He raises some issues that come up once we start to do the updates called for by various cryptographic experts and authorities who\'ve made recommendations on this topic - some of which call for widespread changes to occur in 2010.

Diabetes is a serious complex condition which can affect the entire body. The existing multi-agent-based diabetes diagnosis and classification methods require a number of agents and hence communication between those agents causes time complexity issues. Our method requires only three agents which are user agent, security agent and updation agent. Initially, user agent collects the user symptoms and then encrypts. The encrypted symptoms are then directed to the updation agent. For secure communication two fish-based encryption is used between the user and updation agent. After receiving the encrypted data from the security agent, the updation agent needs to find the diabetes level of user as if it is normal or abnormal. Our proposed technique uses the optimal kernel support vector machine algorithm (OKSVM) with sequential minimal optimisation (SMO) to classify the diabetes level. Based on the optimal kernel, the suggested technique effectively prescribes the drugs for the corresponding user.

ZUC-128 algorithm was listed as the core part in the third international encryption and integrity protection algorithms, EEA3 and EIA3 in 4G-LTE mobile communication system by 3rd generation partnership project (3GPP). ZUC-256 will soon become one of important encryption and integrity protection algorithms in 5G mobile communication system. Compared with software implementations, hardware implementations using field programmable gate array (FPGA) have significant advantages in terms of performance. Implementation's solution for ZUC-256 algorithm was studied by using FPGA as the hardware platform, two optimized implementation algorithms for ZUC-256 were proposed based on linear feedback shift register feedback calculation optimization algorithm and S-box replacement optimization algorithm on the platform of Cyclone IV and Spartan-6. The operating efficiency of ZUC-256 algorithm was verified on two FPGA hardware platforms. The test results show that the optimized ZUC-256 keystream generation algorithm has a main frequency of 209.346 MHz and a throughput of 6.542 Gbps on the FPGA. Optimized ZUC-256 algorithm's performance is improved by 12% compared with the original ZUC-256 algorithm. The running result in our optimized scheme is 214.4% higher than that of the stream cipher algorithm implemented by Kitsos et al., the speed is 95.8% higher than that of the research results from Wang et al., compared with the research results of Zhang et al., this optimized scheme has increased by 45.6%. Moreover, it possesses comprehensive performance advantages compared with the results of Drucker et al. on CCNC 2019. The proposed optimization implementation algorithms for ZUC-256 on FPGA have broad application prospects in the future of 5G system.

Adoption of the Advanced encryption Standard (AES) as a symmetric encryption algorithm for numerous applications requires a low cost and low power design. Presented is a new 8-bit stream cipher architecture core for an application specific integrated circuit AES crypto-processor. The chip area and power are optimised along with high throughput. It is implemented in a 130nm CMOS process and supports both encryption and decryption using 128-bit keys with a throughput of 0.05 Gbit/s (at 100 MHz clock). This design utilises 3152 gate equivalents including an on-the-fly key scheduling unit along with 4.23 mu W/MHz power consumption. Compared to other 8-bit implementations, the proposed design achieves a smaller chip size along with higher throughput and lower power dissipation.

The recording and playback system (RPS) in video conference system needs to store mass of media data real-timely. Considering the security issue, media data should be encrypted before storing. Traditional full encryption and partial encryption algorithms are not applicable to RPS because they could not adjust their speed to meet the throughput variation of media data in real-time RPS. In this paper, a novel lightweight speed-adaptive media-data encryption (SAME) scheme is proposed firstly. Secondly, the SAME is improved to a packet-based algorithm according to the implementation of data storage in RPS system. Thirdly, an RPS oriented queue theory-based autoadaptive speed control mechanism for SAME is designed. Finally, these schemes are integrated into the practical system, that is, AdmireRPS, an RPS of a heterogeneous wireless network-(HWN-) oriented video conference system. Theoretical analysis and experimental results show the SAME is effective enough to support real-time applications. In addition, the proposed schemes also can be used in video surveillance and other video recording systems.

Under the background of the rapid development of information technology, people's data and information security problems are becoming increasingly serious. Data and information can be leaked in daily Internet access or communications. When doing data sharing, the security mechanism of the data sharing platform should be analyzed. This article aims to study how to analyze the security mechanism of cloud computing-based data sharing platforms in the Internet of Things era. This article presented an attribute-based encryption (ABE) algorithm, a detailed interpretation of the attribute-based encryption algorithm, and analyzed security problems in data sharing in cloud computing. The experimental results showed that the ABE algorithm takes an average of 11 s with five trials, while the other two methods take 51.8 and 31.6 s. ABEs take less time for different encryption numbers under the same data than the other two methods and are more efficient than the other two methods. Thus, attribute-based encryption algorithms should have more advantages.

The importance of security in present-day communication networks isundisputed. The security of a network depends not only on the encryption algorithm and securityprotocols that it supports, but even more so on the policies that are used to guide and control theoperations of the deployed algorithms and protocols. As a result, security policies within networkshave received significant attention from the research community recently.
