“…The strength of security in Henon map was previously studied [21]. In many researches, it was proved that Henon method is strong against brute force attack as compared with the classical methods because of having high key space [22]. The size of the key space should be greater than 2 100 to prepare a high-security system [23].…”

Due to the large-scale development in satellite and network communication technologies, there is a significant demand for preserving the secure storage and transmission of the data over the internet and shared network environments. New challenges appeared that are related to the protection of critical and sensitive datafrom illegal usage and unauthorized access. In this paper, we address the issues described above and develop new techniques to eliminate the associated problems. To achieve this, we propose a design of a new sensor node for tracking the location of cars and collecting all information and all visited locations by cars, followed byencryption in a sensor node and saving in the database. A microcontroller of Arduino esp8266 Node MCU board and a GPS module are used. The cryptography uses the chaos-based symmetric-key encryption technique for data. This scheme utilizes a chaotic map (Hénon map) for robustness and security of data. The key sensitivity can be performed by statistical experiments to determine the safety, reliability, and speed of the algorithm. The proposed algorithm presents several exciting features, such as a high level of security, sufficient saving of the energy of the sensor network, and an acceptable encryption speed compared to Advanced Encryption Standard (AES) and Data Encryption Standard (DES).

“…For a 10 -15 floating point precision, all keys parameters (2) introductory status (2) control parameter to produce permutation key can take 10 -15 possible values. Therefore, the key space comes out as 2 198 (10 -15 ) 4 , which is big as much as necessary to defend against "the brute force attack"...…”

“…Although, the four DNA bases and their coding rules are used to encode the data and used as the secret key [2] [3]. On the other side , the chaotic algorithm is characterized by very distinct characteristics such as mixing data the sensitivity of both initial condition and control parameters are all useful in designing cryptographic algorithms for text, images, audios [4].…”

The key to every security system is the important part as it defines if the system is security strength or weakness. Security has become a key issue in digital data transmission over insecure communication network, which can be accomplished using robust ciphering algorithms. "At the other side, the chaotic systems have excellent features, such as Mixing data, ergodicity, sensitivity to initial conditions, control parameters, etc., all of which are useful for designing cryptographic algorithms with large key size and efficient permutation". The addition of using DNA in cryptography creates a novel domain for three reasons:: storage space, computing power and huge parallelism. "This paper presents a hybrid approach of the chaotic map as well as DNA computation to Text" encryption. Two logistic maps are employed for key generation to be used in permutation process, and 1D logistic map is used for generating index permutation. DNA computation coding rules and addition operation are used to frame the final result of the encryption process to produce encrypted text. The proposal results show that the proposal algorithm is highly secure, resistant to brute force attack. and has a bigger key space.

“…According with [11] , these properties are highly related with cryptographic properties to design excellent encryption algorithms with excellent confusion (change only the position of the plain element) and diffusion (change only the value of the plain element) process, and complexity in the source system, which are shown in Table 1 . In recent years, chaotic maps have been employed principally for image encryption at MatLab simulation level, where most of the proposed schemes use the diffusion and confusion architecture with excellent security properties [12][13][14][15][16][17][18][19][20][21][22][23][24] .…”
