Secured Authentication System for Internet of Things
Academic Paper from the year 2024 in the subject Computer Sciences - Internet of Things, IOT, grade: A, Free University of Berlin (The National Institute of Engineering, Mysore), course: Ph.D, language: English, abstract: The key objectives defined in this thesis are given as follows: To analyse the different security breaches in the IoT Ecosystem. To develop a lightweight cryptographic scheme for secured Authentication in IoT. To develop a multilevel security model by using Enhanced Cryptosystem for secured Authentication in IoT. To ensure reliable and secure communication and access across multiple co-operatively communicating devices in IoT ecosystems ensuring optimal security and authentication system is must. Though, IoT demands ensuring security and authentication for both “device level security” and “data security under communication”. Noticeably, the device level security addresses attack resilience from any unwanted or unexpected intruder by applying certain authentication variables or key agreement policies. However, in the last few years, the events pertaining to smart card loss attack (SCLA), Brute-Force attack, impersonation attack, data sniffing attack etc., have questioned major at-hand security solutions. The irony is, in the majority of IoT systems, the access information or the key agreement information is saved or preserved onto the local memory, which often broadens the horizon for data loss, or attack. In such classical approaches the possibility of SCLA, Impersonation and Brute-force attack can’t be neglected. And therefore, ensuring both system level access authentication is inevitable. In other words, strengthening data security in IoT systems is equally significant like device level security and authentication. Once system considers both data level security as well as device level authentication system retaining quality of content and hardware efficiency becomes equally inevitable. On the other hand, maintaining efficacy of the security system with higher authentication correctness amongst the gateways and communication devices is must. It demands a collaborative low-cost or lightweight security model to enable security while maintaining IoT- expectations like low-computation, lightweight computation, low-power consumption, better data quality, attack resilience and fast in response. It can be considered as the key driving force behind this research.
A Secured Architecture for Mitigating Distributed Denial of Service Attack Integrating Internet of Things and Cloud Computing
Doctoral Thesis / Dissertation from the year 2019 in the subject Computer Science - IT-Security, grade: 87 %, Bharathidasan University, language: English, abstract: Internet of Things (IoT) and Cloud Computing play a vital role in the field of Information Technology. The goal of IoT is to link objects of heterogeneous in nature to avail smart services and application anywhere, anytime using any device. Cloud Computing allows computer users to conveniently rent access to fully featured applications, to software development and deployment environments, and to computing infrastructure assets such as network-accessible data storage and processing with its salient features of on-demand self-service, broad network access, resource pooling, rapid elasticity, and measured service. Though the Cloud and IoT have emerged as independent technology, merging these two technologies brings renaissance in the field of future networks and in building smart environment. This new evolvement is known as CloudIoT. One of the important challenges in CloudIoT is security. Challenges on the integration of the Cloud within IoT are to be a major bottleneck. The integration of security mechanism and data privacy are also a major concern. Any leakage of information from any of the CloudIoT could severely damage the privacy and authenticity of the users and data. Researchers all over the world put on efforts in integrating smart CloudIoT services to satisfy the needs of the CloudIoT Users. But no prominent architecture has been authenticated so far. Hence, it is imperative to design architecture to integrate CloudIoT smart services and applications to access smart services in a secured manner at anywhere, anytime. The major challenges in implementing this scenario are security factors such as authenticity, confidentiality, integrity, and privacy. In network security, there are several types of attacks which can harm the network resources and services. Distributed Denial of Service (DDoS) is one of the malicious attacks which can harm data communication in CoT potentially. There is a problem that may render customers to withdraw from the cloud services. A traditional DDoS attack aims at servers and/or the bandwidth of a network or a website in order to make them unavailable to their intended users. However, attackers can generate DDoS attack to harm the cloud resources in the same way as the cloud has a huge pool of resources which are larger than attackers resources.
