As a popular conception, the Internet of Things (IoT) allows people to access more and more data around the world. However, a concern arises of how to store the large amount of data created through this technology. To solve the problem, cloud computing services are brought in as a critical technology. However, it is necessary to guard the private information that is collected via IoT devices and stored in distributed cloud servers. Though authentication schemes are provided, many security weaknesses exist. We present an advanced authentication scheme for cloud computing using only hash functions and exclusive or computations that are suitable for IoT devices, which tend to have limited computation and storage abilities. © 2012 IEEE.

Authentication Protocol for Distributed Cloud Computing: An Explanation of the Security Situations for Internet-of-Things-Enabled Devices

IEEE Consumer Electronics Magazine

Wireless Sensor Network (WSN) is a very important part of Internet of Things (IoT), especially in e-healthcare applications. Among them, wireless medical sensor networks (WMSNs) have been used in the personalized healthcare systems (PHSs). In recent years, professionals use their mobile devices to access the data collected from sensors which are placed in or on patients’ bodies. Due to the danger of wireless transmission circumstance, the security of the data which are collected by the sensors and also transmitted to the doctors faces challenges. In the past decade, many authentication schemes for WMSNs are proposed. However, security disadvantages have been found in such schemes. To overcome the historical security problems, we propose a robust and lightweight authentication scheme for WMSNs, which meets the common security requirements, and keeps away user tracking from attackers. The popular tool Proverif is employed to express that our scheme resists the simulated attacks. Also, the informal security analysis is demonstrated. With the comparison to several very recent schemes and simulation by NS-3, the proposed scheme is suitable for PHSs. © 2017 Elsevier B.V.
