1. Introduction

The rapidly growth of information networking technology (ICT) is main principals for common culture interchanging of the data very considerably. Since the huge amount of data transferred over the communication facility, data security modified the issue. The security requires in order to guard such data which communicates on unsecure channel [1]. The modification that occurred from past until now is create a generation in the security and changed to automated security [2] or online security. Attributable to the development of ICT to necessity reputation of data has directed to the mentioned secure data in several methods. The Insecure information as considered one of the difficulties at the present time with the development of ICT and the use of Internet networks through data correspondence between various sides such as organizations and users. The term security of information refers to a methodology that employed to satisfy the security requirements [3]. The Encryption method is one of the targets that make users to ensure the secrecy and access of the data to the receiving from side without affecting it from any third party. Also, the algorithms of Cryptography prevent third party or public reading of private messages [4]. The working of Encryption and decryption is shown in Figure 1 [5]. The Figure 1 states that users Encrypts the message using secret key and send it through the communication channels. The Decrypt by Receiver the message using the secret key but Cryptography offers a number of security target to ensure the privacy of data with non-modification of data and so on. the great security advantages of Cryptography that widely in nowadays security [6].

Cryptography algorithms can be intitled two important categories: Symmetric key Cryptography and Asymmetric key cryptography [7]. Figure 2 shows three types of Cryptography.

2. Classification of Cryptography

2.1. Symmetric Key Cryptography

Symmetric algorithm is also called shared key Cryptography. During data transmission, the sender and the receiver share the same key for Encryption and Decryption [5]. The different types of Symmetric algorithms as same as to Data Encryption Standard (DES), Triple Data Encryption Standard (3DES), Advanced Encryption Standard (AES) and Blowfish [8]. Hence, AES is a type of symmetric key cryptography and very powerful and more reliable than the other.

2.2. Asymmetric Key Cryptography

Public key Cryptography is another name for the Asymmetric Algorithm with two keys element that namely ‘Private key’ and ‘Public key’. While the data transmission the users encrypts the clear text with the help of public key known as the cipher text and the receiver Decrypts this cipher text with the help of its private key [8]. The different types of asymmetric algorithms are Rivest Shamir Adlemen (RSA), Diffie Hellman (DH) and Digital Signature Algorithm (DSA), ECC [8].

2.3. Hybrid Cryptography

The concept which combines the both shared key cryptography and public key Cryptographic techniques create new version of algorithms and mentioned as Hybrid Cryptography. A Hybrid Cryptosystem is a protocol using Symmetric and Asymmetric Cryptographic technics together, each to its best advantage. Hybrid Encryption is considered a highly secure type of encryption as long as the public and private keys are fully secure. Hybrid Cryptography is achieved through data transfer using unique session keys along with Symmetrical Encryption. public key Encryption is implemented for random Symmetric key Encryption. The recipient then uses the public key Encryption method to Decrypt the Symmetric key. Once the Symmetric key is recovered, it is then used to Decrypt the message [9]. The blended OR combined in between Symmetric and Asymmetric Cryptographic techniques and create Hybrid Cryptography with three key. However, the three key Hybrid must be more secure than the two key Asymmetric and one key Symmetric. The Table 1 below show the comparison between three different algorithms in respect of key type namely; Symmetric Cryptography, Asymmetric Cryptography and Hybrid Cryptography.

Table1: Shows the comparison between three different algorithms

3. Related Work

In [7], a comparative theory of techniques Encryption in terms of (Symmetric and Asymmetric) keys to algorithms analyzed. In the Symmetric key Encryption (AES) algorithm is found to be better in terms of cost, security and implementation.

Nevertheless, the Asymmetric key Encryption (RSA) algorithm is much better in terms of speed and security. Nevertheless, in paper [7] show and discover that the two algorithms namely AES and RSA are good individually in term of the security and cost but didn’t mention Hybrid techniques OR combined technique simultaneously. The AES with RSE are combined in our proposed system and came out with better results than before Paper [10] by Verma, P. Guha, and S. Mishra that comparative study of different key algorithms namely: AES, DES, 3DES, Blowfish and RSA are analyzed and compared with the results that found among the symmetric encryption algorithm, AES and Blowfish are the most secure and efficient algorithms. The performance and energy consumption of these algorithms are better compared to the others. In case of Asymmetric Encryption algorithm, RSA is secure and can be used for application in wireless network because of its good speed and security. However, in paper [10] show and compare between: AES, DES, 3DES, Blowfish and RSA algorithms individually but didn’t mention Hybrid techniques OR combined technique simultaneously working between mentioned techniques. The AES, DES, 3DES, Blowfish and RSA algorithms are NOT combined and results came out individually.

In paper [11], ECC is explained in detail. Elliptic curve Cryptography (ECC) is a relatively newer form of public key Cryptography that provides more security per bit than other forms of Cryptography still being used today .

In paper [12], Encryption and Decryption of text using ECC is explained with mapping technique. It is concluded that ECC has low power consumption, less memory requirement, small key size and high security.

In paper [13], Hybrid Cryptography technique using AES and ECC is proposed. The system is intended to provide security to a variety of multimedia data ranging from text documents, images, audio, video. Proposed Hybrid system capable of Encrypting and Decrypting the sensitive data to protect it from unauthorized access and attacks.

In paper [14], Hybrid Cryptography approach implemented using AES and ECC. This system provides encryption to the multimedia data such as text, image, audio, video which resulted in an output with 100 percent accuracy without any loss of information.

In paper [15], Different text files are taken as input and encrypted using AES-ECC Hybrid approach. Analysis of AES Encryption with ECC is done on the basis of different parameters like storage requirement, Encryption time, Decryption time.

In paper [16], Hybrid approach for Encryption technique is implemented over a binary image, which provides more accuracy to the encryption process. The ECC and AES are combined in such a way that differentiates them from the usual manner of Encryption. These days with the increasing trend of security it becomes essential to protect the data and information in a better way.

4. Problem Definition

Cryptographic techniques provides the secure data transmission in automated performance analysis of E-services by AES-Based Hybrid Cryptosystems with RSA, ElGamal, and ECC which be a target for our proposed system. The complications existing systems such as a Cryptographic technique with time consume processes. Nevertheless, exactly techniques that isn’t includes the reliability checks on transmitted data and another issue in key changing the presence of security. Thus, the implement an operational Cryptographic algorithm in all phases must be well thought-out to sort a strong method (i.e. AES-Based Hybrid Cryptosystems with RSA, ElGamal, and ECC) with complications in to the proposed method. The proposed Hybrid Cryptographic technique which uses the best features of Symmetric AES-Based Hybrid Cryptosystems with RSA, ElGamal, and ECC. The designed technique helps to reduce the time complexity in Encryption-time, Decryption-time and Throughput-time. This paper solves the performance in time consume also select fewer time response by throughput-time. Finally, our proposed algorithms AES-Based Hybrid Cryptosystems with RSA.

5. Description of Algorithms

Advanced Encryption Standard (AES), Rivest Shamir Adleman (RSA), Elliptic Curve Cryptography (ECC), and ElGamal are indeed powerful cryptographic procedures and use for different purposes and have different features. The AES is a Symmetric-key algorithm widely used for secure facts encryption while RSA operates as an Asymmetric-key algorithm for secure communication and digital signatures. ECC, another asymmetric- key algorithm, relies on elliptic curves for enhanced security with shorter key lengths. ElGamal, also asymmetric are utilized for public-key Encryption and digital signatures based on the discrete logarithm problem. In below explain in detail about all types of Algorithms.

5.1. Advanced Encryption Standard (AES)

The AES algorithm are operating as a Symmetric block cipher system that employs a replace or exchange network. The data block length and key length in AES can be adjusted based on specific requirements, with key lengths available in 128, 192, and 256 bits. The iteration cycle numbers for these round keys are 10, 12, and 14 rounds, respectively. The AES algorithm primarily comprises three components: round change, turns, and key expansion. Each round transformation consists of a non-linear layer, a linear mixture layer, and an add round key layer. The Encryption process of AES is illustrated in Figure 3. Also, there are three different key lengths with round key iteration.

5.2. Elliptic Curve Cryptography (ECC)

In order to compare the public key cryptography that is comparatively more established by an elliptic curve cryptography (ECC) because offers more security per bit than other Cryptographic methods that are still in use nowadays technologies. Nevertheless the Mathematically an elliptic curves are cubic curves that are equivalent to tori topologically. Despite their name which is not closely related to the ellipse. The name of elliptic is integral. By Weierstrass normal equation form. The basic general elliptic curve used for cryptography is of the equation form

which showed in Figure 4. The Curves of this form are defined by different values for 𝑎 and 𝑏 and modifying these values to visualize of the curve and expand, contract, or pinch off to be two separate pieces. Practically the Curves used for Cryptography to defined very large integer values for 𝑎𝑎 and 𝑏𝑏 respectively. The modification of a and b in the mentioned equation is modify the elliptic curve visualization. This mean that is a direct relation between a and b values and elliptic curve.

5.3. RSA Algorithm

The invented of the most widely Asymmetric key cryptosystem known as RSA algorithm is very powerful and user- friendly algorithms that Encryption and authentication Cryptosystem used since that time in many Cryptographic applications for instance an e-mail security, banking, e-commerce and digital signature over web operating systems over the internet facility.

The main security algorithm depends on the difficulty of finding prime numbers factor of large integers. RSA operation consists of three main stages key generation, Encryption and Decryption processes which are explained briefly in following [18].

5.3.1. Key Generation

• Select two large prime integer numbers 𝑝 and 𝑞 to calculate the modulus 𝑛 using the formula 𝑛 = 𝑝 × 𝑞.
• Calculate ∅ using the formula ∅(𝑛) = (𝑝 − 1) × (𝑞 − 1).
• Select an integer 𝑒 which is the public exponent, such that GCD (𝑒, ∅(𝑛)) = 1,
• where GCD refers to greatest common divisor function between two numbers.
• Calculate 𝑑 which is the private exponent, such that 𝑒 × 𝑑 = 1 𝑚𝑜𝑑 ∅(𝑛), where 𝑚𝑜𝑑 symbolizes to the modulus operation or the reminder after division.

Hence, (𝑛,𝑒) represents the public Encryption key, while (𝑛, 𝑑) represents the private decryption key [18]. The two prime numbers are the target of the algorithms.

5.3.2. Encryption/Decryption Processes

Let 𝑚 be a message that wanted to be encrypted, then the encrypted message 𝑐 is calculated via the public key (𝑛, 𝑒) using the equation: 𝑐 = 𝑚^𝑒 𝑚𝑜𝑑 𝑛. To extract the original message 𝑚, the received encrypted message 𝑐 is decrypted via the private key (𝑛, 𝑑) using the equation: 𝑚 = 𝑐^𝑑𝑚𝑜𝑑 𝑛 [18].

5.4. ElGamal algorithm

Security mentioned algorithm depends over hard to calculating discrete logarithms of large prime numbers. If the same plaintext is encrypted using this cryptosystem, then a different cipher text is obtained in each time of Encryption. El- Gamal operation can be described in 3 main steps:

1. key generation, 2) Encryption and 3) Decryption processes which are explained briefly as follows.

5.4.1. Key Generation

• First, select a random prime number 𝑝 and two other random numbers 𝑥 and 𝑔, such that both of them are less than 𝑝.
• Calculate 𝑦 using the formula: 𝑦 =𝑔𝑥 𝑚𝑜𝑑 𝑝.
• Thus, (𝑝, 𝑔, 𝑦) represents the public key which can be shared between a group of users, while 𝑥 represents the private key which should be kept secret [19].

5.4.2. Encryption/Decryption Processes

In order to Encrypt a message 𝑚, firstly, a random integer number 𝑘 is selected, such that 𝑘 is relatively prime with
(𝑝 − 1). Secondly, the cipher text pairs (𝑐1, 𝑐2) is calculated using the equations: 𝑐1 = 𝑔^𝑘𝑚𝑜𝑑 𝑝 and 𝑐2 = (𝑦^𝑘 ×𝑚) 𝑚𝑜𝑑 𝑝. Finally, the cipher text (𝑐1, 𝑐2) is transmitted to the recipient. To Decrypt the cipher text, pair (𝑐1, 𝑐2), the private key 𝑥 is employed to recover the original message 𝑚 using the equation: 𝑚𝑜𝑑 𝑝 [19].

The following pseud codes for ElGamal Algorithms namely Key Generation, Encryption and Decryption. Figure 5: Pseudo-code key generation stage: encryption and decryption.
