The goal of this work is to develop a key exchange solution for IPsec protocol, adapted to the restricted nature of the Internet of Things (IoT) components. With the emergence of IP-enabled wireless sensor networks (WSNs), the landscape of IoT is rapidly changing. Nevertheless, this technology has exacerbated the conventional security issues in WSNs, such as the key exchange problem. Therefore, Tiny Authenticated Key Exchange Protocol for IoT (TAKE-IoT) is proposed to solve this problem. The proposed TAKE-IoT is a secure, yet efficient, protocol that responds to several security requirements and withstands various types of known attacks. Moreover, TAKE-IoT aims to reduce computation costs using lightweight operations for the key generation. The proposed protocol is validated using the automated validation of internet security protocols and applications (AVISPA) tool. Hence, results show that TAKE-IoT can reach a proper level of security without sacrificing its efficiency in the context of IoT.

The Internet of Things (IoT) is viewed as a dynamic technological revolution representing future communications and computing in several areas. It introduces physical objects in the sphere of cyber world. IoT is not about a single technology but various complementary technological developments which provides ways to bridge the gap between the real world and the virtual world. A number of wireless sensor technologies are implemented in IoT viz. RFID, ZigBee, actuators, WiFi and wireless sensor networks (WSNs). This paper presents various key technologies involved in IoT and its detailed architecture. IoT architecture explains function of each layer with respect to the technologies and the devices that surround each layer. Each layer has its specific security issues. This paper presents various security threats related to each IoT layer and the specific security requirements. Information security, data protection, and user's privacy are among important key areas in IoT. This paper in the nutshell presents new challenges posed by IoT so that further work can be undertaken in creating a robust, efficient and smart environment for IoT based applications.

Authenticated Key Exchange Protocol

In wireless sensor networks, users sometimes need to retrieve real-time data directly from the sensor nodes. Many authentication protocols are proposed to address the security and privacy aspects of this scenario. However, these protocols still have security loopholes and fail to provide strong user anonymity. In order to overcome these shortcomings, we propose an anonymous authenticated key exchange protocol based on Elliptic Curves Cryptography (ECC). The novel protocol provides strong user anonymity such that even the gateway node and the sensor nodes do not know the real identity of the user. The security of the proposed protocol is conducted in a well-defined security model under the CDH assumption. Compared with other related protocols, our protocol is efficient in terms of communication and enjoys stronger security. The only disadvantage is that our protocol consumes more computation resources due to the usage of asymmetric cryptography mechanisms to realize strong anonymity. Consequently, our protocol is suitable for applications which require strong anonymity and high security in wireless sensor networks.

We put forward exchange agreement certificate mutual authentication and the session key exchange protocol based on wireless sensor network, which is an improved version of the traditional certificate protocol. In the optimization scheme, the adversary cannot obtain the secret value, and each session process generates a different key, so as to ensure the safety of the encrypted information transmission between nodes.
