“…F(m, x n , K, R) has a chaotic characteristic in an expanded range that is larger than the existing range of 1D chaotic maps. In the case of the parameters K and R in the range of [2,26] and [1,3], respectively, the new suggested chaotic map has a high complex chaotic behaviour. The m, K and R range has been experimentally confirmed by bifurcation and LE in the following subsection.…”

“…Here, c represents the controlling parameter that has the range [0, 2], v n ∈ [−2, 2] represents the produced chaotic sequence. In the case of parameter c ∈ [1.4, 2.0], the Quadratic map has a chaotic behaviour [26]. Even when c ∈ [1.4, 2.0], there are some values that make the quadratic map has no chaotic sequence.…”

Chaotic maps that can provide highly secure key sequences and ease of structure implementation are predominant requirements in image encryption systems. One Dimensional (1D) chaotic maps have the advantage of a simple structure and can be easily implemented by software and hardware. However, key sequences produced by 1D chaotic maps are not adequately secure. Therefore, to improve the 1D chaotic maps sequence security, we propose two chaotic maps: 1D Improved Logistic Map (1D-ILM) and 1D Improved Quadratic Map (1D-IQM). The proposed maps have shown higher efficiency than existing maps in terms of Lyapunov exponent, complexity, wider chaotic range, and higher sensitivity. Additionally, we present an efficient and fast encryption method based on 1D-ILM and 1D-IQM to enhance image encryption system performance. This paper also introduces a key expansion method to reduce the number of chaotic map iteration needs, thereby decreasing encryption time. The security analyses and experimental results are confirmed that 2D Correlation Coefficient (CC) Information Entropy (IE), Number of Pixels Change Rate (NPCR), Unified Average Changing Intensity (UACI), Mean Absolute Error (MAE), and decryption quality are able to meet the encryption security demands (CC = −0.00139, IE = 7.9990, NPCR = 99.6114%, UACI = 33.46952% and MAE = 85.3473). Furthermore, the proposed keyspace reaches 10240, and the encryption time is 0.025s for an image with a size of 256 × 256. The proposed system can yield efficacious security results compared to obtained results from other encryption systems.

The main goal of this work is to create an application that has the ability to communicate, connect, and control physical entities via the Internet. This purpose can be achieved by the Internet of Things or Internet of everything (The more complete form) which is a new revolution of the Internet to allow objects to be connected to the internet. Connected objects can communicate with each other or with us via an HTML interface that allows to create a communication between the user and the server ESP8266 through its IP address. Objects have been connected wirelessly (WiFi communication). A sensor is used to collect data then transfer it to the user via the Internet in order to make correct decisions in anywhere at any time.
