Simulation-Based Performance Validation of Homomorphic Encryption Algorithms in the Internet of Things

Abstract

IoT systems consist of Hardware/Software systems (e.g., sensors) that are embedded in a physical world, networked and that interact with complex software platforms. The validation of such systems is a challenge and currently mostly done by prototypes. This paper presents the virtual environment for simulation, emulation and validation of an IoT platform and its semantic model in real life scenarios. It is based on a decentralized, bottom up approach that offers interoperability of IoT devices and the value-added services they want to use across different domains. The framework is demonstrated by a comprehensive case study. The example consists of the complete IoT “Smart Energy” use case with focus on data privacy by homomorphic encryption. The performance of the network is compared while using partially homomorphic encryption, fully homomorphic encryption and no encryption at all.As a major result, we found that our framework is capable of simulating big IoT networks and the overhead introduced by homomorphic encryption is feasible for VICINITY.

Ciphertext Database Audit Technology Under Searchable Encryption Algorithm and Blockchain Technology

“…The homomorphic encryption algorithm can solve the problem. When the user processes the encrypted data with various algorithms, any plaintext content will not be disclosed in this process (Kölsch et al, 2019;Vengadapurvaja et al, 2017;Min et al, 2019). Through the server provider, the user processes the whole data with the homomorphic encryption algorithm:…”

IoT Technology Applications-Based Smart Cities: Research Analysis

“…Table 8 contains the 20 main keywords associated with this cluster. The fifth research line has developed contributions on the concept of "Internet" in relation to smart cities based on IoT technology applications, as a decentralized set of interconnected communication networks that use the Transmission Control Protocol/Internet Protocol (TCP/IP), guaranteeing that the heterogeneous physical networks that comprise it constitute a unique logical global network [132,133]. Cluster 6 (cyan color) is led by "Cloud Computing" (occurrences: 88, link: 249, total link strength: 799,), and it groups 8.70% of the keywords.…”

Visual and Artistic Effects of an IoT System in Smart Cities: Research Flow

“…They have been, and will continue to be, the bridge between man and machine [10][11][12][13][14][15]. Integrate visual tools for interactive consultation into smart cities, such as apps or interfaces for urban control, security, and pollution allow citizen participation and interaction with their environment, as well as the detection of opportunities and improvements in city services [16][17][18]. Some examples of IoT devices that generate useful visual effects are light panels that produce visual and audible alerts for better orientation of drivers, notifying in turn that a failure has occurred in a car on a road, and thus alerting drivers, traffic officers and other drivers and avoiding accidents.…”
