Abstract
With emerging of the Internet, the way we communicate with each other has fundamentally revolutionized. The second development wave of the Internet is not about people, but will be about smart connected devices. Although more than a decade passes from the proposing of "Internet of Things" concept, the deployment of this concept has been done slowly for various reasons such as lack of required technologies development and security challenges. We must spend more time to understand the security challenges and available solutions, when we speak about smarter environments and technologies such as IoT. In this paper, we attempt to analysis existent threats and vulnerabilities in the area of security and privacy of Internet of Things using a systematic approach, while presenting a survey of the solutions proposed in the literature. Finally, research opportunities of this area will be discussed.

Abstract
RPL (Routing Protocol for Low Power and Lossy Networks) has been designed for low power networks with high packet loss. Generally, devices with low processing power and limited memory are used in this type of network. IoT (Internet of Things) is a typical example of low power lossy networks. In this technology, objects are interconnected through a network consisted of low-power circuits. Example IoT applications are smart energy grid, smart home, connected car, intelligent transport systems, and smart cities. IoT is different from many similar technologies due to the existence of low power electronic circuits and limited connectivity. Information security is one of the main IoT concerns. The emergence of new types of security vulnerabilities in IoT devices and the escalation of their damages through numerous IoT applications is considered a major deployment drawback for RPL. In this paper, major cyberattacks against RPL, as well as related security solutions are addressed. Then, these solutions are classified and their weaknesses and strengths are investigated. Finally, it discusses the state-of-the-art status of information security in RPL.

Abstract
Privacy preservation in healthcare monitoring systems has always been a concern for both patients and doctors. To address this issue, many protocols have been designed. In this article, we examine the proposed scheme by Nasr Esfahani and colleagues, evaluating it from a security perspective. Their proposed scheme uses a three-layer hierarchical template chain to store and maintain critical medical information of patients in a centralized and secure manner. Additionally, by using Zero-Knowledge Proof (ZKP) and ring signature methods, they demonstrate that their scheme protects medical data against both internal and external attacks. According to potential scenarios, the Nasr Esfahani et al. protocol has shown good performance against many attacks, such as storage attacks and replay attacks, but it is vulnerable to integrity violation attacks. The success probability of the attacks presented in this article is one, and the complexity is only a single execution of the protocol.
